Health packaging foreign new products and more

Recently, foreign countries have successively introduced new types of food packaging materials and packaging containers to meet the needs of various food quality, freshness, safety, convenience, speed, and environmental protection.

Chicken Feather Plastic Materials Japan's Kyoto Women's University has developed a new plastic-like material extracted from waste chicken feathers by smashing feathers, heating them up to 160 degrees Celsius, and compressing them after a few minutes. The new material has high bending strength, good heat resistance and water resistance, is easy to process, has good feel and appearance after forming, and can be used as a new material for food packaging containers.

Measurable pathogen packaging material Toxinalert Canada developed a new packaging material that can detect pathogenic bacteria, using a protein-based antibody testing system. The package can detect four pathogens Salmonella, Campylobacter, E. coli and Listeria. The color change reaction occurs when the package comes into contact with contaminated food. The package can also be used to detect protein properties of pests or genetically engineered foods. Packing material can be processed into any shape, suitable for different product needs. 80% of the composition of the polymer film, the other is metal foil and plate.

Transgenic test membranes France has introduced new packaging films processed from ordinary polyvinyl chloride (PVC) materials that can be used to identify the use of genetically modified raw materials for packaged foods. Using this specially treated PVC film, it can be determined whether the contents of the package, such as soybean oil, are made from genetically modified soybean material, even if only 5% to 10% of the soybean product is confirmed. It is mainly used to package non-genetically modified soybeans cultivated in southern Europe as a follow-up inspection and to ensure that no genetically modified soybean material can be incorporated during the circulation process.

Aroma Packaging American Mecormick launched a new type of aroma packaging material, which is a non-aluminum foil PErfrma paperboard, containing special coatings, can keep the aroma unchanged for 3 years, and has anti-ultraviolet radiation function, used as packaging sheet.

Anti-counterfeit seal paper The paper mill in Montreal, Canada, develops and manufactures self-adhesive sealing papers for packaging foods, avoiding the trouble of binding bundles with cords during packaging. The outer layer of the paper is kraft paper, which can be used for writing and printing. The inner layer is a special polypropylene foam material. It is tough, non-toxic, moisturizing, heat preservation and other functions. The sap, flavor and smell of the packaged food will not leak out. Detachment will lose its viscosity and it will have some anti-counterfeiting features.

Corn packaging corn packaging material developed in Germany can replace plastic packaging. The production method is to beat the corn powder, and after being squeezed and expanded by the pressure machine to make particles, it can withstand the impact pressure, anti-static, anti-fog and environmental pollution. The use of special processing techniques and equipment in the processing of corn flour for packaging materials, and the addition of vegetable oil-like additives and ground grass roots to the formulated slurry can increase the particle stability. Corn packaging is a bio-packaging material and has a strong competitive advantage.

Water-free gas packaging Japan introduced fast-saturated food packaging materials. The material is composed of polypropylene, polyethylene film, paper aluminum foil and multi-layer materials. When heated, water vapor condenses on the surface of the film and is absorbed by the paper to prevent water vapor from soaking the food.

Collagen film packaging The collagen film packaging material developed in the United States is made of animal protein collagen and has excellent properties of high strength, good water resistance and water vapor barrier. When the food is thawed and cooked, it will melt and eat, and the food in the package will not change. taste.

Lightweight packaging paperboard Finland has introduced a new type of packaging paperboard, which is 10% to 20% lighter than ordinary paperboard. It has no special odor and its heat resistance is the same as pure pulp board. It is particularly suitable for packaging chocolate, ice cream, refrigerated food, and aroma packaged fast food boxes.

Lightweight natural packaging materials Lightweight natural packaging materials made in Brazil, made from natural corn, soybeans, ramie, etc., can replace foamed plastic and eliminate white pollution.
