Food packaging film launched six new varieties

Food plastic packaging is one of the most active branches in the field of packaging materials. People are constantly raising the quality of life and food safety requirements, and have also put forward more and more requirements and higher and higher standards for the function of food packaging. Under this circumstance, the development of new varieties of plastic film for food packaging in various countries around the world is also very active to meet the personalized needs of the market to the utmost.

Packaging film that can identify genetically modified raw materials France introduced two new packaging films processed from ordinary polyvinyl chloride (PVC) materials to the market, which can be used to identify whether the packaged food uses genetically modified raw materials. Using this specially treated PVC film for packaging, it is possible to identify whether the package contents such as soybean oil are processed from the genetically modified soybean material, even for soybean food containing only 5 to 10% of the genetically modified components. It is mainly used to package non-genetically modified soybeans planted in southern Europe as a follow-up inspection and to ensure that they cannot be blended with genetically modified soy materials during circulation.

BOPE anti-counterfeiting film for salt packaging Shandong Xinlik Plastics Co., Ltd. has successfully developed BOPE anti-counterfeiting film for packaging purpose. The key technology is to add several kinds of nano-scale special additives to the production raw materials, and then obtain the BOPE film through a gradual biaxial stretching process. Just take the money detector and take a look, the colorless packaging film will emit a bright light, can play a good anti-counterfeiting effect on the iodine-added food, anti-counterfeiting performance is good. The film also has the advantages of good barrier properties, UV resistance, and safe use.

Salad oil anti-UV shrink packaging machine' target = _blank> transparent film China's Kerry oil imports and develops UV-resistant shrink film for packaging Arowana AE salad oil, can well protect the vitamin content of oil from ultraviolet radiation , Protecting nutrients is not destroyed. The film is a packaging machine 'target = _blank> transparent film, the appearance of crystal clear and translucent, to overcome the inconvenience caused by blocking the UV line using the unpackaged machine 'target = _blank> transparent film material packaging to consumers. The film utilizes a variety of advanced technologies such as spectrum analysis, nanotechnology, nutrition, and hygiene to incorporate a substance that effectively absorbs ultraviolet rays, that is, ultraviolet sensitized granules, to protect the vitamins in the oil. damage.

Double-layer superimposed film of packaged meat France introduced a two-layer superimposed film dedicated to packaging meat to the market. The outer layer is a high-density polyethylene film with special structure and properties, and the inner layer is edible paper. The superposed bilayer membrane is semi-transparent, the film is very thin, and its thickness is only 12 micrometers, but its strength is good, safe, non-toxic and can be directly contacted with meat products. Packaging the meat with the film can solve the problem that ordinary materials packaged meat will be immersed in bleeding and grease, and will not easily separate on the meat and cause the surface to form a hard skin, so as to maintain the original color, fragrance and taste of the meat.

Special coating film for microwave oven heating Switzerland recently developed and produced a special cover film for microwave oven products—Shimkashin. The film is not only resistant to high pressure, but also has good anti-fog properties. The use of this cover film is particularly useful for heating various dishes in a microwave oven, which can be quickly and conveniently heated for food. Dishes made of various vegetables, fish, poultry, and meat can be directly fed into a microwave oven for microwave under pressure without the need of adding liquid excipients when microwave-heated using this special film cover material package (when the cover material is polypropylene). Cooking. During the heating process, the pressure generated by water vapor can be safely released through the membrane.

Measuring the packaging film of pathogens Canada developed a packaging film that can detect pathogenic bacteria, using protein-based antibodies to detect. The packaging film can detect Salmonella, Escherichia coli, Listeria and other pathogens, when contact with contaminated food, the color change reaction occurs, so as to determine the contamination of pathogens, to prevent food damage to humans.
