Research and development trends of various special films for food packaging

smokeless smoked fish film. Japan has successfully developed a unique product, smoked free fish film, which can make the smoking process of different kinds of fish, especially salmon, easier and faster. This new product has a layer of plant fiber glue film soaked with wood vinegar, which does not contain any toxic substances. The process of smoking the product with this film is simple. After the fish is cured, wrap a layer of plant fiber glue film on the outside, put it into a vacuum bag, and place the product for 48 hours to fully taste. The smoked fish will not produce smoke, and there is no need for special liquid spray or washing the smoking machine

identify the packaging film of 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 can identify whether its packaging contents, such as soybean oil, are processed from genetically modified soybean raw materials. Even for soybean food containing only 5% ~ 10% genetically modified ingredients, it will bring a breakthrough change to China's EPS industry, which can be clearly identified. It is mainly used for packaging non GM Soybeans Planted in southern Europe as a follow-up inspection and to ensure that they cannot be mixed with GM soybeans in the circulation process

BOPE anti-counterfeiting film for salt packaging. Shandong xinlik Plastic Co., Ltd. has successfully developed a special BOPE anti-counterfeiting film for packaging. The key technology is to add several nano-sized special additives to the production raw materials, and then prepare BOPE film through the step-by-step biaxial stretching process. As long as you take out the money detector and take a photo, the colorless packaging film will emit bright light, which can play a good anti-counterfeiting effect on iodized food and has good anti-counterfeiting performance. The film also has the advantages of good barrier, strong UV resistance, no harmful substances, meeting the hygienic requirements of food packaging, safe use and so on

anti UV shrinkage transparent film of packaged salad oil. The anti ultraviolet (UV) shrinking film introduced and developed by Kerry grain and oil in China is used to package arowana AE salad oil, which can well protect the vitamin components in the oil from UV radiation and protect the nutritional components from damage and loss. The film is transparent film with a crystal clear appearance, which can overcome the shortcomings that enterprises use impervious film materials to block UV lines to package consumers. The film comprehensively utilizes a variety of advanced technologies such as spectral analysis, nanotechnology, nutrition, hygiene and so on. A material that can effectively absorb ultraviolet rays, namely ultraviolet photosensitive decomposition particles, is incorporated into the packaging material and has excellent flexibility. The particles do not allow ultraviolet rays to enter the bottle and destroy vitamin

double layered laminated film for packing meat. France introduced a double-layer laminated film specially used for packaging meat to the market. Its outer layer is high-density polyethylene film with special structure and performance, and its inner layer is edible paper. The superimposed double-layer film is translucent, very thin, and only 12 microns thick; However, it is strong, safe and non-toxic, and can be directly in contact with meat products. Packaging meat products with this film can solve the problems of bleeding and grease in ordinary materials, which are not easy to separate from the meat and form a hard skin on the surface, and can maintain the original color, aroma and taste of meat

special cover film for microwave oven heating. A Swiss company has recently developed, produced and introduced to the market a special cover film for microwave oven products, simkahin. The film is not only resistant to high pressure, but also has good fog resistance. The cover film is specially used for heating various dishes in a microwave oven, which can be quickly and conveniently heated for eating. Dishes composed of various vegetables, fish, poultry and meat are packed with this special film capping material (the capping material is polypropylene) and can be directly put into the microwave oven for microwave cooking under pressure without adding liquid excipients. In the heating process, according to the specific requirements, the pressure generated by water vapor can be safely released through a special valve, namely the membrane

measure the packaging film of pathogenic bacteria. A Canadian company CD and DVD discs are one of the most potential markets. It has developed a packaging film that can detect pathogenic bacteria, which can be detected by protein based antibodies. The packaging film can detect Salmonella, Escherichia coli, Listeria and other pathogenic bacteria. When it comes into contact with contaminated food, it will have a discoloration reaction, so as to determine the presence of bacterial pollution and eliminate the harm of food deterioration to human beings
