The rise of the kraft paper packaging market is inseparable from the wider use of it. Now no matter from electronic products to peripheral accessories, from food packaging to ordinary packaging, kraft paper packaging can be seen everywhere. Kraft paper packaging has the advantages of non-toxic and non-polluting. It is easy to degrade, has very good physical strength, good tensile force and burst resistance, and can be recycled many times, in line with modern people’s environmental protection concept. The products packaged by it can not only prevent the product packaging from being damaged, but also prevent the product from being mildewed. It has strong fastness and moisture resistance. Therefore, kraft paper has been more and more widely used in the market.
Compared with other packaging bags such as paper-plastic composite bags, kraft paper packaging bags have obvious advantages. So, what are the advantages of kraft paper packaging bags?
1. Good toughness, strong breaking resistance and good printing effect. Because of people’s nostalgia, natural kraft paper is highly sought after by the public. With the development of the times, kraft paper bags have always been respected. 2. Kraft paper packaging bags are also very environmentally friendly. With the improvement of people’s awareness of environmental protection, in order to cooperate with the marketing of products, enterprises choose kraft paper as product packaging, which will be more favored by consumers and is also a marketing method.
2. Excellent processing performance. Compared with shrink film, kraft paper has certain cushioning performance, anti-drop performance, good toughness, strong break resistance, mechanical parts processed by the product, and good cushioning, which is convenient for compound processing.
3. The degradation rate of kraft paper in the soil is fast. It belongs to the new “Four No Products”, which is non-toxic, tasteless, harmless, non-polluting, environmentally friendly and recyclable. Compared with plastic bags, kraft paper packaging bags will quickly degrade even if they are piled up in the soil. Will not pollute the environment!
4. The printing effect is good. The special color of kraft paper is a bright spot in itself. Only simple lines can outline the beauty of the product pattern during printing. The packaging effect is better than plastic packaging bags, and the printing cost is greatly reduced. The production cost and production cycle of its packaging.
5. The paper adopts PP coating film, which plays a waterproof role. The thickness of the bag material can be made from one to six layers according to the customer’s requirements. The opening and back cover methods are divided into heat sealing, paper sealing and paste bottom. Multi-layer kraft paper bag: There are perfect composite materials of imported kraft paper and domestic kraft paper, kraft paper and PP new material woven cloth. PE plastic bags can be added in the bag, which fully meets food-grade requirements. You can choose the packaging that suits you arbitrarily.
In shopping malls and other shopping places, kraft paper bags are generally used for packaging. The colors of kraft paper are white, brown, brown, and yellow. It can satisfy everyone’s choice of handbag color, and the kraft paper has a very good printing effect. It is an ideal substitute for plastic packaging bags. In addition, for some frozen materials, kraft paper can also meet the requirements. Generally speaking, the temperature of frozen food varies greatly, and the strength of the packaging paper is the main factor that needs to be considered for frozen food. In terms of strength, cowhide is significantly better than other types of paper. For example, KFC or McDonald’s should be the best examples. Here we can see the shadow of kraft paper. Kraft paper is not only used for food, but also has a better effect as a tea packaging bag. The tea leaves are wrapped in thin kraft paper and tightened to prevent the tea leaves from getting wet. In general, kraft paper packaging has become a universal packaging for specialty products, snacks, and snack foods. It is becoming more and more popular. Choose Zekun packaging to customize a kraft paper packaging with an exclusive pattern, which can be applied to different occasions. It also plays a good role in promoting the brand image of the product!
With the continuous enrichment of various types of convenience foods, there are also various packaging forms of food, especially cooked food packaging. Since it is directly related to the health of the public, whether it is packaging form or packaging type, it will be affected by the public. The wide attention of the company, the quality of packaging is also constantly improving. The editor of Hunan Zekun will introduce the difference between vacuum cooking bag and vacuum boiling bag.
First explain the retort pouch. The cooking bag vacuum bag is a kind of plastic packaging bag that can be heated. It is mainly made of three-layer composite material. It has the functions of preventing light, moisture, air leakage, temperature resistance, shading, and fragrance. It is a high-temperature cooking vacuum bag. The series of products have a high level of hygiene, will not cause damage to the built-in food, and the products are more cost-effective. The use of retort bags and vacuum bags can meet the requirements in a short time, and preserve as much of the original color, aroma, taste and shape of the food as possible. Retort bags and vacuum bags are used to package various cooked meats and high-temperature sterilized foods, such as meat, ham, grilled fish, etc. Very convenient to use.
The material of the cooking bag: NY/PE, NY/AL/RCPP, KNY/PE.
There are three types of retort bag sterilization:
The first type: general sterilization, the cooking temperature is 100-200℃, and the sterilization is about 30 minutes
The second type: high temperature type, the cooking temperature is 121℃, and the sterilization is about 45 minutes
The third type: high temperature resistant type, the cooking temperature is 135℃, and the sterilization is about 15 minutes
Next, explain the boiled bag.
Material of boiled bag: PET/PE BOPA/PE PET/AL/PE
The characteristics of the boiled bag: it can withstand the sterilization treatment at a temperature not higher than 105 ℃, does not delaminate, does not leak the bag, has good oil resistance, has good printability, and prints beautifully. The heat sealing strength is very good, the puncture resistance is good, and the impact resistance is also high.
Boiled bags are sterilized by water, and there are two types of sterilization for boiled bags:
The first type: low-temperature sterilization, sterilization at a temperature of 100 ℃ for about 30 minutes.
The second type: bus sterilization, sterilization at 85 ℃ temperature environment for about 30 minutes.
In short, there is not much difference between retort bags and boiled bags, and both need sterilization treatment.
Recently, the EU’s most stringent “plastic limit order” came into effect three years after its promulgation. Once the ban on plastics is implemented, all plastic products in the EU including biodegradable plastic products, it will be banned from production and sales. Of course, the catering industry is most affected by the plastic ban. Convenient packaging containers such as disposable tableware, packaging boxes, straws, and plastic bags will all become history, replaced by reusable products made of paper, wood and stainless steel. It is worth noting that the bill believes that all currently degradable plastics come from fossil fuels and organisms, so they are also included in the ban. For Chinese companies, it is necessary to pay special attention to the new measures of the European Union, especially for Chinese companies engaged in the trade of disposable tableware and other related products, to pay special attention to the EU’s biggest crackdown on such products this time, and carry out relevant measures in a timely manner. Adjustment.
The most strictly prohibited plastic order
The ban imposed by the EU this time has already been “reminded” earlier. As early as 2019, the EU passed this rather strict plastic restriction bill. The bill clearly states that before July 2021, disposable plastic products, including plastic straws, tableware, balloon rods, and even packaging made of decomposable plastic, must be fully withdrawn from the markets of all EU countries. All plastics Manufacturers are no longer allowed to produce related products, and only allow existing stock products to enter the market, achieving complete digestion within 3 years. In addition, the bill does not open up a network of plastic products that currently have no alternative products, but proposes further restrictive measures: the bill requires manufacturers and consumers of these plastic products to bear corresponding economic responsibilities, and to Responsible for pollution and waste management issues, and reduce the utilization rate by at least 25% by 2025.
The EU’s “Strict Plastic Restriction Order” is also forced by reality. According to relevant statistics, the EU produces an average of 26 million tons of plastic waste each year, but only 30% of it is recycled and the rest Most of them are “barbarically” disposed of by incineration or landfill. The plastic particles produced after treatment pollute the soil, rivers and even the ocean.
After all, the degradation rate of plastic products is extremely slow, and it will take at least 200 years to complete the degradation. The ecosystem and ecological balance have been severely damaged.
In the past, many plastic products on the EU market came from China, especially disposable plastic tableware. After the strictest plastic restriction order is implemented, Chinese companies must adjust their business thinking in a timely manner, explore new “fist products” for export trade, and reduce the impact of the plastic restriction order. In addition, my country is also beginning to pay attention to the problem of plastic pollution, and many places are also actively carrying out plastic-limiting activities and initiatives. The National Development and Reform Commission has also banned the production of ultra-thin mulch film.
Next, let’s talk about China
Since the introduction of the new “plastic ban” in January 2020, the introduction of the provincial “plastic ban” policy has been significantly accelerated, and many provinces and regions have successively issued local “plastic bans.” The pace of the ban on plastics in various provinces is similar. They will be piloted in several major cities in 2020, and the province will be promoted in 2022, and the goal of banning plastics in the province will be reached in 2025. According to the central and local policies, in the next 2-5 years, the ban on plastics will be rolled out across the country, and the degradable plastics industry is expected to achieve rapid development.
A reporter from Hainan Daily learned on the 14th from the Hainan Provincial Department of Transportation that, starting from July, in accordance with the relevant requirements of Hainan Province on the “ban on plastics” and the unified deployment of the Hainan Provincial Department of Transportation and the Hainan Provincial Market Supervision Administration, the Hainan Provincial Strait The Office takes the lead and cooperates with the Haikou Municipal Transportation and Port and Shipping Bureau, the Market Supervision Administration and the Comprehensive Law Enforcement Bureau to carry out a five-month joint law enforcement inspection of “plastic ban” on the Qiongzhou Strait ferry transportation channel in Xinhai Port and Hainan Railway Nangang, and increase the number of ports and terminals The intensity of supervision of the “ban on plastics” work.
The plastic ban is bad news for entrepreneurs who invest in the development of bioplastics. Their research results also belong to the scope of the ban.
And the current ban is not all, and the use of plastic packaging will be further restricted in the next few years. From 2022, the packaging of filter cigarettes, sanitary napkins, drinking cups and sanitary wipes will carry warnings stating where they should be disposed of. From January 5, 2023, plastic manufacturers will have to start to contribute to the cleaning of snack bags, small shopping bags and other items. What they need to do is still under study. On July 3, 2023, caps on packages with a capacity not exceeding 3 liters must be attached to the bottles. The European Commission also hopes that in the future, at least 30% of all plastic bottles will be made of recyclable materials.
Nowadays, plastic products have become important objects that damage the earth’s environment, as well as pollutants that cause the destruction of marine ecosystems. However, in recent years, people’s use of plastic products has become more and more serious, especially when online shopping is increasing day by day. Almost every item will be packaged with plastic products.
Statistics show that in 2015, the length of tape used in the express delivery industry could circle the earth 425 times. Moreover, when this data is rapidly increasing to 2018, the use of this product has reached 39.8 billion meters, which is equivalent to driving nearly 1,000 times around the earth. By 2019, the express industry will send 7.08 million express parcels to the whole country every hour, and almost all of these express parcels are packaged in plastic products.
Driven by the concept of environmental protection, in recent years, the country has begun to ban the use of non-degradable plastic products, but these products have become indispensable items in daily life. How to solve this problem of demand and pollution? As a result, some companies have developed biodegradable plastic products, which have reduced environmental pollution a lot, but the production costs that need to be paid are very high. Therefore, although some places are implementing pilot projects, most cities or vegetable market restaurants still use ordinary traditional plastic bags.
Now that 2021 has entered, what is the progress of the implementation of biodegradable plastic bag products? Judging from the use of plastic bags in some pilot urban shopping malls or supermarkets, these places have already vigorously used biodegradable plastic products, and in the near future, these plastic bags will be implemented nationwide. As a result, many business operators saw the business opportunities and believed that this was a hugely profitable industry.
Future development space for biodegradable plastic bags
Understand the market space of biodegradable plastic bags, it is not difficult to find that if these products are used to replace traditional plastic products, a market of more than 2 million tons will be obtained. Under the influence of the new policy, 100,000 tons of plastic bags will be replaced in supermarkets, shopping malls and restaurants, and hundreds of tons of plastic bags will be replaced in the logistics and express industry. This shows how impressive the prospects of this new product are.
Therefore, in the next time, the degradable plastic bags will usher in a big market explosion, with a huge market potential, and this new type of product has been supported by the state, and now some differentiated competition has been formed. Its marketing quota must be very impressive. For entrepreneurs, if you choose this project, there is indeed a lot of profit margins.
Judging from the policies implemented by the country, the market for these biodegradable plastic bags will usher in a big explosion. Nowadays, many manufacturers have joined the production of biodegradable plastic bags. Based on a comprehensive analysis of current policies and environmental protection concepts, environmentally friendly plastic bags or other products will become the next wealth creation outlet. What do you think?
The high-temperature cooking bag is a composite plastic film bag that can be heated. It has the advantages of both canned containers and boiling water-resistant plastic bags. Therefore, it is also called “soft cans”. After more than ten years of use, it is proved to be an ideal packaging container for sales. The cooking bag is mostly made of three layers of materials. The typical structure of the cooking bag is: the outer layer is polyester film for reinforcement; the middle layer is aluminum foil for light, moisture and air leakage; the inner layer is polyolefin Film (such as polypropylene film) for heat sealing and food contact.
Today, the editor of Zekun will take you to popularize science about several materials and applicable fields of high-temperature cooking bags:
Can be used as a material for cooking bags
1. PET film
BOPET film is made of PET resin extruded by T film and then biaxially stretched. It has excellent performance.
(1) Good mechanical properties. The tensile strength of BOPET film is the highest among all plastic films. Very thin products can meet the needs, with strong rigidity and high hardness.
(2) Cold resistance and excellent heat resistance. The applicable temperature range of BOPET film is from 70 to 150°C, and it maintains excellent physical properties in a wide temperature range, which is suitable for most product packaging.
(3) Good barrier performance. It has excellent comprehensive water and gas barrier properties. Unlike nylon, which is more affected by humidity, its water blocking rate is similar to PE, and the air permeability coefficient is extremely small. It has extremely high barrier properties to air and odor, and is one of the fragrance-preserving materials.
(4) Chemical resistance, grease resistance and most solvents, dilute acids, dilute alkalis, etc.
2. BOPA film
BOPA film is a biaxially stretched film, which can be made by simultaneous biaxial stretching by a blow molding method. The film can also be biaxially stretched step by step by T-die extrusion method, and can be made by simultaneous bidirectional stretching by blow molding method. The characteristics of BOPA film are as follows:
(1) Excellent strength and toughness. The tensile strength, tear strength, impact strength and rupture strength of BOPA film are among the best plastic materials.
(2) Outstanding flexibility, pinhole resistance and not easy to pierce the contents are a major feature of BOPA. It has good flexibility and makes the packaging feel good.
(3) Good barrier properties, good fragrance retention, and resistance to chemicals other than strong acids, especially oil resistance.
(4) The temperature range is wide, the melting point is 225℃, and it can be used for a long time between -60~130℃. The mechanical properties of BOPA remain stable at low and high temperatures.
(5) The performance of BOPA film is greatly affected by humidity, especially dimensional stability and barrier properties. When BOPA film is damp, except for wrinkles, it generally stretches laterally. Longitudinal shortening, the elongation rate can reach up to 1%.
3. CPP film
CPP film is a cast polypropylene film, which is a non-stretched, non-oriented polypropylene film. According to the raw materials, it is divided into homo-CPP and copolymer CPP. The main raw material of cooking-grade CPP film is block copolymer impact-resistant polypropylene. The performance requirements are: the Vicat softening point temperature is greater than the cooking temperature, the impact resistance is good, the medium resistance is good, and the fish eyes and crystal points should be as few as possible.
4. Aluminum foil
Aluminum foil is the only metal foil among flexible packaging materials, used for packaging items that have a long application time. Aluminum foil is a metal material, and its water-blocking, gas-blocking, light-shielding and taste-preserving properties are unmatched by any other packaging material. It is a packaging material that cannot be completely replaced so far.
5. Ceramic Evaporated Film
Ceramic evaporation film is a new type of packaging film. It is a film obtained by using plastic film or paper as the substrate and vaporizing and vaporizing metal oxides on the surface of the substrate in a high vacuum equipment. The characteristics of the ceramic evaporation film are mainly:
(1) Excellent barrier properties, almost comparable to aluminum foil composite materials.
(2) Good transparency, microwave permeability, high temperature resistance, suitable for microwave food.
(3) Good fragrance retention. The effect is the same as glass packaging, and it will not produce peculiar smell after long-term storage or high temperature treatment.
(4) Good environmental protection. Low combustion heat, less residue after incineration.
6. Other films
(1) PEN film
The structure of PEN is similar to PET. PEN has various properties of PET, and almost all properties are higher than PET. Excellent comprehensive performance, high strength, good heat resistance, good barrier properties, transparency, and excellent UV barrier properties are PEN’s The biggest highlight, PEN’s barrier to water vapor is 3.5 times that of PET, and its barrier to various gases is four times that of PET.
(2) BOPI film
The operating temperature range of BOPI is extremely wide, reaching -269~400℃. The film that has been reacted has no melting point, and the glass transition temperature is between 360~410℃. It can be used continuously for more than 15 years at 250℃ in the air, and there is little change in performance. . BOPI has excellent comprehensive properties, high physical and mechanical properties, radiation resistance, chemical solvent resistance, dimensional stability, softness and folding resistance.
(3) PBT film
PBT film is one of thermoplastic polyester films, namely, butylene terephthalate film. The density is 1.31~1.34g/cm, the melting point is 225~228℃, and the glass transition temperature is 22~25℃. PBT film has better performance than PET film. PBT has excellent heat resistance, oil resistance, aroma retention and heat sealability, and is suitable for the production of microwave food packaging bags. PBT film has good barrier properties and can be used to package flavored food. PBT film has excellent chemical resistance.
(4) TPX film
TPX film is made by copolymerization of 4-methylpentene-1 and a small amount of 2-olefin (3%~5%). It is the lightest specific gravity among all plastics, only 0.83g/cm, and other properties are also very excellent. In addition, TPX has good heat resistance and is the material with the best heat resistance among polyolefins. It has a crystalline melting point of 235°C. It has good weak mechanical properties, high tensile modulus and low elongation, strong chemical resistance, oil resistance, and high acid resistance. , Alkali, water, resistance to most hydrocarbons, solvent resistance temperature up to 60℃, surpassing all other transparent plastics, high transparency, light transmittance of 98%, crystal clear appearance, strong decoration, and microwave penetration powerful.

1．Application of D2W Oxidation of Biological Products:
D2w oxidizing biodegradable additives are suitable for various PE (such as: HDPE, LDPE, LLDPE, CPE, MDPE), PP (BOPP, OPP), and PS products and other materials. 99%PE (polyethylene)+1%d2w (oxidizing biodegradable additive)
Biodegradation is defined as a phenomenon caused by oxidation and cell-mediated simultaneous or sequential progress.
2．What is D2W Oxidation of Biological Degradation (D2W Oxidation of Biological)
D2w is a low-cost additive that can degrade polyethylene and polypropylene plastics into a biodegradable form. The plastic molecular chains are first broken down into small units, so that microorganisms can decompose these small units into carbon dioxide and water. Soon after the product with additives is manufactured, the degradation reaction begins. However, adding stabilizers to the oxidative degradable plastic additives delays the action of the additives with oxygen, and does not undergo the degradation reaction within the regulated time, so it can The product life can be adjusted for the product. d2w’s additive engineering breaks the carbon molecular bonds of plastics, resulting in lower molecular weight and loss of material strength. The material strength is gradually broken, but plastics will not only become plastic fragments, but under atmospheric pressure and external pressure, the molecular weight will be less than 40,000 Daltons. Microorganisms can decompose these small molecular units, which is “biodegradable.” This process will continue until the plastic becomes carbon dioxide, water, cell biomass, and trace elements.The same is plastic, adding d2w will produce unexpected effects!
Plastic is a strong, durable, lightweight, safe and versatile raw material. Plastics will eventually degrade, but this process will take decades, or even hundreds of years, to happen. This is a very long time. During this period, if these plastics are not recovered or recycled, they will cause serious environmental pollution. But if we switch to our d2w plastic products, we can effectively control or reduce this “white pollution” problem. Whether in the sea, land, sewers, woods, parks or other places, as long as there is oxygen, d2w biodegradable plastic products will begin to decompose in the natural environment after the predetermined service life. Once the degradation process starts, it will continue.
3．Classification of Bio-degradable
Basically, there are two main methods for plastic biodegradation, oxo-biodegradable and hydro-biodegradable. Both are chemically decomposed first, the former is through oxidation, the latter is through hydrolysis, and then biological decomposition is carried out. Both decomposition will release carbon dioxide, but hydro-biodegradable will also produce methane (CH4). Both methods can decompose plastics, but only oxo-biodegradable can be recycled. In addition, the hydro-biodegradable method is much more expensive than oxo-biodegradable.
d2w oxidative biological double degradation has passed the American ASTM standard (ASTM 6954-04) test. The degradation process includes (stage) oxidative fragmentation and (second stage) biodegradation-which meets the standard of degradation in the environment.
Plastic products manufactured by science and technology can be oxidized and decomposed. The principle is to add a small proportion (usually 1%) of additives (pro-degradant) that can help decompose in the process of manufacturing plastics, thereby changing the plastics characteristic. When the product loses efficacy or is not needed, that is, when the product’s life cycle is set (controlled by additives), the degradation effect will begin to emerge. The process conforms to ASTM 6954-04 and is certified by RAPRA. With this biodegradable plastic technology, existing machinery and labor can be used, so little or no additional costs are required. d2w? Additives not only break the plastic into small pieces, but also break down the plastic from the molecular structure level into specific small units by the additives, so that microorganisms (bacteria and fungi) can enter and take up carbon and hydrogen and decompose further. This is “Biodegradable”. This process will continue until the material is decomposed into carbon dioxide, water and biomass (Biomass), and there will be no residual organic polymers in the soil. Oxo-biodegradable plastic has passed all common ecotoxicity tests (ecotoxicity tests) under the international standards of ON S 2200 and ON S 2300, including tests for seed germination, plant growth, and animal survival (water fleas and earthworms).
5．D2w advantages:
（1）. d2w compatible with the ecological environment
（2）. No plastic fragments will remain in the soil
（3）. Pass the ecotoxicity test
（4）. Can be in contact with food for a long time
（5）. Does not contain organic chlorine, PCBs or heavy metals
（6）. Does not emit methane and nitrous oxide, even if it is buried in a landfill
（7）. Recyclable
（8）. Can be made into compost
Controllable plastic life:
We can provide customized plastic products according to your specifications and requirements to control the final service life. We have five degradation cycles: 6 months, 12 months, 18 months, 24 months, and 36 months. d2w completely decomposed plastic products under normal storage conditions, from the date of manufacture (printed on the additive packaging bag), the product has a shelf life of 14 months. It is recommended that you use additives within this shelf life.
d2w additive storage method: Put the product in the original packaging bag, away from direct sunlight, and place it in a dry and cool environment, and the temperature cannot exceed 29°C (85°F). Do not place the product inside the car, in a warm garage or under outdoor scaffolding, and do not subject the product to mechanical pressure or external pressure.
The pet industry is summarized by all pet-related industries such as pet living, pet food, pet medical treatment, pet clothing, pet cages, pet grooming, pet supplies, pet boarding, pet intermediaries, pet platforms, industry organizations, pet media, etc. Collectively. As of today, the top market share in the pet industry is still pet living, food, medical treatment, beauty and supplies. In terms of pets, dogs and cats dominate and have the largest market share.
China’s pet food industry is developing rapidly, and pet food companies are bound to intensify competition in 2018. Old brands will continue to conquer the market, expand sales areas, and speed up consumer awareness of product brands; new brands emphasize functional foods, and More innovative advertising planning creativity, win people’s hearts and win the market. The relevant government departments will also increase random inspections, control and supervision of the pet food industry to prevent the proliferation of unhealthy and illegal pet food.
In the midst of the COVID-19 health crisis, packaged products became more important than ever. Concerns over food safety, a desire for products with an extended shelf life, and the explosion in demand for e-commerce almost overnight created unique challenges for those in the CPG industry. The only trend for a while seemed to be unpredictability.
Pet food suppliers saw a sudden surge in demand for their products as many American, faced with the idea of spending months alone at home, headed to the shelters to adopt pets.
Back in March 2020, faced with COVID-19 related restrictions, pet food sales accelerated faster than ever as owners stocked up. One large pet supply company reported a 300% increase in freight volumes! After March, sales dropped off for a while as owners depleted their stock. As August 2020 came around, however, pet food sales pulled ahead of 2019 numbers.
What this means for the packaging industry: Increased and unstable demand for pet food means growing demand for packaging solutions that enable manufacturers and contract packagers to push safe, shelf-stable product out the door faster.Demand for dry, shelf-stable pet food, especially in bulk, means increased demand for flexible plastic pouches, especially with zipper reclosures.
Hunan Zekun Packaging Technology Co., Ltd.is a professional modern automation enterprise in the research, development, sale and service of pet food Packages.For more information about pet bag packaging, please visit our website: https://www.zekunpackaging.net https://www.zekunpackaging.com
In the era of pursuing western trends, western food have occupied Chinese dining tables.Coffee are becoming more and more popular among white-collar workers in today’s cities apparently .In addition to the strong aroma of coffee, the most important factor of coffee is that it can be refreshing, especially “Italian coffee, espresso” although the content of caffeine is low, but the effect is more refreshing.In modern society, people need to maintain a clear mind, strong physical strength, and the ability to cope with very intense working conditions.This is a very important job guarantee in the extremely competitive job market in modern commercial society.
The editor of Zekun teaches you how to choose refined coffee. Good coffee needs high-quality packaging. The best way to pack coffee is to have a coffee packaging bag with a one-way exhaust valve. The one-way exhaust valve is designed to allow air pressure. Escape from the inside of the package while preventing air from entering. Since freshly roasted coffee beans release carbon dioxide, the one-way exhaust valve allows roasters to immediately pack their products without worrying about the coffee bag breaking.
The role of the one-way exhaust valve coffee bag:
The coffee beans will continue to release carbon dioxide several times the volume of the coffee beans themselves for a period of time after roasting. In order to prevent the coffee packaging from bursting and isolate it from sunlight and oxygen, a one-way valve aluminum foil packaging bag is designed to discharge the excess carbon dioxide out of the bag outer.
The one-way exhaust valve can block the oxygen outside the coffee bag from entering the bag, preventing the coffee beans from oxidizing and causing the aroma to quickly spread, effectively ensuring the dryness and mellow flavor of the coffee beans, and the bag will not be caused by the accumulation of carbon dioxide. It expands, and at the same time prevents the coffee beans from being entered by outside air and accelerated oxidation.
When the gas produced by the coffee sealed in the bag reaches a certain pressure inside the bag, the gas can push the exhaust valve plate from the inside to the outside, and the excess gas is discharged outward; when the pressure in the bag is reduced to not enough to open the valve plate It closes automatically, and the packaging bag returns to the sealed state.
The first thing you see when buying coffee beans is the packaging and the label on it. The best storage environment for coffee beans is low oxygen, dryness, low temperature and low light. Coffee bags with one-way exhaust valve can meet the above storage environment. One-way exhaust valves are divided into two types, one with a filter and the other without a filter. Under normal circumstances, we recommend a valve without a filter for coffee beans, and a valve with a filter for coffee powder. Gas valve. Generally, the shelf life of green coffee beans is one to two years, and the shelf life of cooked beans after roasting is within one month. In any case, the coffee bean packaging bag is only to help extend the coffee bean’s freshness period, or the most important thing is to drink it as soon as possible.
Eco Friendly Smell Proof Aluminum Foil Stand Up Coffee Bag with Valve
Eco Friendly Smell Proof Aluminum Foil Stand Up Coffee Bag with Valve .This degassing valve allows you to package coffee at the peak of flavor immediately following the roasting process. An inner aluminum layer provides added protection from moisture and oxygen. General zipper and E-zipper can be provided.
If you get the COVID-19 vaccine, you won’t get infected?
Some people may think that if you get the COVID-19 vaccine, you won’t get infected, but that’s not true. After you get the vaccine, you can only reduce the risk of infection.
Zhong Nanshan said: “In addition to vaccine prevention, the most effective way to treat the new crown is multiple monoclonal antibodies, but only now has it been discovered that some of the antibodies have failed against the new crown virus strain. So we have been facing challenge one by one. The mutation of the virus strains currently encountered will bring great challenges to our prevention. It will make the vaccine ineffective and may also reduce the effect of antibody treatment.” At present, in addition to vaccination prevention, it is essential to prepare masks and other prevention and control materials. Roll film packaging provides clean and hygienic masks for these prevention and control materials.
Editor Zekun will tell you some basic knowledge about automatic packaging roll film as below:
lAdvantages of automatic packaging roll film:
Roll film packaging bags are used in automatic packaging machinery. When manufacturing packaging film rolls, packaging manufacturers only need to perform printing operations, without any edge sealing work, and are supplied to buyers in rolls. Due to the transportation of rolls, the transportation is reduced. cost. Larger brand companies or companies that require the same kind of packaging bags for a long time have chosen to directly purchase packaging film and use automatic packaging machines to make them into bags. In fact, the process of packaging film and packaging bags is the difference in bag making processes. Therefore, the emergence of roll film simplifies the entire process of plastic packaging into three major steps: printing-transportation-packaging, because roll film packaging is fully electric and integrated, and the machine is self-packed, which can save materials when using automatic packaging roll film. , Save labor, save time, is the best choice for small package products.
lThe usage of automatic packaging film:
Application scope of automatic packaging film: hardware screws, electrical parts, snack foods, stationery, small toy parts, cosmetics, agricultural products, powder packaging, liquid packaging, etc. Features: Good heat sealability, low material cost, automatic packaging can save manual packaging costs.
According to the usage, it can be divided into heat sealing film and laminated film:
1. Heat sealing film:
Single layer heat sealing film, mainly BOPP heat sealing film, CPP film, used for hardware screws, electrical parts and other independent packaging.In daily life, milk tea, porridge and other small shop site packaging sealing machine, it is used to seal the film is the film, the most common film packaging is bottle packaging, and generally use POF film, such as part of Coke, mineral water and so on.
2.laminated roll film:
The structure of the laminated roll film is based on the characteristics of the packaging product. There are three and four layers in generally. The outer layer material is polyester, nylon, stretched polypropylene, paper, etc. The middle layer material is aluminum foil, aluminum, polyester, nylon, etc. The inner layer material is cast polypropylene, polyethylene, etc. Different laminated film structures are usually formulated according to the three-layer materials. The laminated roll film is suitable for vacuum packaging or general packaging of food, electronic products, chemicals, medicine, tea, precision instruments and cutting-edge defense products.
lMaterial of automatic packaging laminated film:
1) PET/PE laminated film:
The material of OPET/LDPE composite film is polyethylene terephthalate and high-pressure polyethylene. It is usually abbreviated as PET/PE laminated bag. It has the characteristics of high transparency and good oxygen barrier. It can be used as a mask packaging film, and Since this laminated film has good heat and cold resistance, it can also be used as a packaging bag for quick-frozen food and retort food.
2) BOPP/CPP laminated roll film:
The materials of BOPP/CPP laminatedfilm are biaxially oriented polypropylene and unstretched polypropylene, which are customarily called OPP/CPP laminatedfilm bags. Among all laminatedfilms, it has relatively high transparency. Compared with single-film plastic bags, the cost is higher than single-film plastic bags at the same thickness, but the hand feel is better than single-film bags; and because of the good moisture barrier properties of this kind of film, it is used in food, mainly for packaging Dry foods and fast foods, such as biscuits, instant noodles, etc. The disadvantage is that it has poor high temperature and cold resistance, and it is not suitable for packaging refrigerated and high-temperature sterilized food.
3) OPP/PE laminated roll film:
The BOPP/LDPE laminated film is laminated of two-way stretched polypropylene and high-pressure polyethylene laminated film bags, generally abbreviated as OPP/PE laminated film, which is the largest variety of plastic films, with good flexibility, high elongation, and hardness Low-roll film, its oil resistance effect is also good, so cooked food and some oil products are also packaged in this bag.
lSterilization method of automatic packaging roll film
The air contains a lot of microorganisms and bacteria that are invisible to the naked eye. If the sterilization effect of the packaged food container is not obvious or the protection is improper, it may cause secondary pollution, and human consumption of contaminated food will cause harm to the body. For people’s health and safety, we usually sterilize the roll film. So how can sterilization be truly effective to protect the safety of food? For automatic packaging roll film sterilization, we adopt two special sterilization methods:
1) Ozone sterilization:
Ozone is a strong oxidant, and its sterilization process is a biochemical oxidation reaction. Ozone first acts on the cell membrane, causing damage to the components of the cell membrane, leading to metabolic disorders. Ozone continues to penetrate the cell membrane to destroy lipoproteins and lipopolysaccharides in the cell membrane, changing the permeability of the cell and leading to cell death.
Using ozone sterilization to sterilize production equipment and products can improve the quality and grade of food packaging roll films.
2) UV sterilization:
Ultraviolet sterilization is the use of ultraviolet wavelengths to destroy the molecular structure of DNA or RNA in bacteria and viruses, forming growth cell death and regenerative cell death, to achieve the effect of sterilization and disinfection.
Taken together, the penetration ability of ultraviolet rays is relatively poor, but the cost of the two methods is not much different, so Ze Kun editor here suggests that you should use ozone sterilization for food packaging roll film, the purpose is to increase the sterilization area So as to achieve a better sterilization effect.
warm prompt:
Even if the vaccine is developed we cannot treat STH lightly, after all, according to the current research results, the vaccine is not foolproof, antibody does not always exist, immune duration is only 6 months, although we believe that the vaccine is safe and effective, but after vaccinated against new crown, or require you to maintain personal protective measures,This includes habits such as wearing masks, maintaining social distance and washing your hands frequently, since vaccines aren’t 100 percent protective.
