Food cold bags

Japan launched a household food cooling bag, consisting of a double layer of vinyl film, about 20cm long and 16cm wide. The surface of the outer layer is coated with a polymer water-absorbing polymer coagulant, and the water will slowly infiltrate into the bag and form a gel-like cooling agent. Then put it in the refrigerator and cool it for use. When traveling, people can take cold or cold drinks from the refrigerator and put them in cold-keeping bags to take them with them. It is suitable for midsummer use. Grain anti-mildew package Japan's Mitsubishi Chemicals Co., Ltd. developed a new kind of grain anti-mildew bag, which is made of polyolefin resin film and contains 0.01%~0.05% vanillin. It can slowly volatilize and penetrate into food, and it can inhibit for a long time. Molds can make food produce a pleasant fragrance. Temperature Control Packaging The United States 3M Corporation developed a THIN桽UITE plastic non-woven fabric that can be used to make food packaging that can withstand heat and cold. 3M and L-POIMT have also developed a temperature-controlled package that monitors the temperature of the food in the package.
