International new food packaging materials and containers

recently, foreign countries have launched new food packaging materials and containers to meet the needs of food quality, freshness, safety, convenience, rapidity and environmental protection

Kyoto Women's University in Japan has developed a new plastic like material extracted from discarded chicken feathers. The method is to crush the feathers, heat them to 160 ℃, and then compress them for molding after a few minutes. The new material has high bending strength, good heat and water resistance, easy processing, good hand feel and appearance after molding, and can be used as a new material for food packaging containers

Canadian toxinalert company developed a new packaging material that can detect pathogenic bacteria, using a protein based antibody detection system. The packaging material can detect Salmonella, Campylobacter, Enterobacter 0157 and Listeria (the author is the deputy director of the Development Research Department of China Mining Federation). Discoloration reaction occurs when the packaging material contacts the contaminated food. The packaging material can also be used to detect the protein characteristics of pests or genetically engineered foods. Packaging materials can be processed into any shape, suitable for different product needs. 80% of the components are polymer films, and the rest are metal foils and plates

Sendai packaging company in Japan has developed non-woven fabrics with antibacterial and fresh-keeping functions, which are used to make anti-bacterial and fresh-keeping packaging boxes to contain fish and other foods. This kind of packaging box will produce weak energy, activate fish tissue enzymes, prevent the internal water from dissociating and prevent food corruption. It is used to contain vegetables and fruits, which can properly absorb the water accumulated on the surface of vegetables and inhibit the growth of miscellaneous bacteria. It is suitable for packaging household baskets and outdoor tourism food

France launched a new packaging film processed from ordinary polyvinyl chloride (PVC) materials, which can identify whether the packaged food uses genetically modified raw materials. Using this specially treated PVC film for packaging can determine whether the packaging contents, such as soybean oil, are made of trans base soybean raw materials, even if it only contains 5%-10% soybean food. It is mainly used for packaging non GM soybeans cultivated in southern Europe as a follow-up inspection and to ensure that GM soybeans cannot be mixed in the circulation process

mecormick company of the United States launched a new fragrance packaging material, which is aluminum foil free perfrma paperboard. It contains special coating, which can keep the fragrance unchanged for 3 years, and has the function of preventing ultraviolet radiation. It is used as packaging board

Montreal paper mill in Canada developed and produced self-adhesive sealing paper for food packaging, avoiding the trouble of binding and binding with string during packaging. The outer layer of this paper is kraft paper, which can be used for writing and printing. The inner layer is a special polypropylene foaming material, which is tough and non-toxic. It has the functions of moisturizing and heat preservation. The juice, flavor and smell of the packaged food will not leak out. Once unpacked, it will lose its viscosity, and has a certain anti-counterfeiting function

corn packaging materials developed in Germany can replace plastic packaging. The production method is to beat corn flour, compress, extrude and expand it into particles by a liquid press, which can withstand impact pressure, anti-static and anti fog, and do not pollute the environment. In the process of processing packaging materials from corn flour, special processing technology and equipment are used, and additives similar to vegetable oil and ground grass roots are added to the prepared slurry to increase particle stability. Corn packaging is a biological packaging material, which has a strong competitive advantage

Dano meat and dairy company of France extracts lactic acid from beets to make yogurt boxes and cups, which ferments raw materials into lactic acid and extracts water to form propyl ester. There are usually two reference conditions: ① standard reference conditions; ② The reference conditions of the experiment are that it is processed into poly cheese, mixed with minerals, and installed in the machine to make light and solid materials, which can be made into boxes and cups, and can replace all the packaging of dairy products. The packaging material is an ecological packaging material, which can be decomposed as fertilizer and does not pollute the environment

Japan launched quick ripening 4. Food packaging material before holding the test piece. This material is composed of polypropylene, polyethylene film, paper and aluminum foil. When heated, the water vapor condenses on the surface of the film and is absorbed by the paper, which can prevent the water vapor from soaking the food

collagen film packaging material developed in the United States is made of animal and plant protein collagen. It has high strength, good water resistance and excellent performance of isolating water vapor. When food is thawed and cooked, it will melt and be edible, and the food in the package will not change the taste

Finland introduced a new type of packaging board, which is 10%-20% lighter than ordinary board, has no special smell, and has the same heat resistance as pure pulp board. It is especially suitable for packaging chocolate, ice cream, refrigerated food, and flavor packaged fast food boxes

light natural packaging materials made in Brazil, refined from natural corn, soybeans, castor beans, can replace foamed plastics and eliminate white pollution

Japan's central chemical company recently developed a food container that can inhibit dioxin and has been put on the market. The container is a disposable convenience container and a cooked food container. Polypropylene and talc powder are highly mixed into sheets, which are formed by hot village molding. The material itself will not produce any gas that reacts with dioxins, such as hydrogen chloride, and can absorb the hydrogen chloride gas produced by other wastes during combustion, thereby inhibiting the production of dioxins. According to the test of authoritative institutions, the dioxin produced by the burning of this material is reduced by half, and the carbon dioxide is reduced by 25% compared with the previous products after inhibiting the occurrence of dioxin
