Vacuum bag, also known as decompression packaging, is carried out according to the principle of atmospheric pressure. The main function of vacuum bag is to remove oxygen, so as to prevent food mildew and deterioration. Vacuum packaging is the process of pumping out the oxygen in the packaging bag and food cells with an air extractor, so that microorganisms lose their “living environment”. Vacuum bag can also prevent food oxidation, make food taste unchanged, deteriorate and reduce the loss of vitamin A and C.
Vacuum packaging materials are usually made of double-layer composite film or three-layer aluminum thin composite film. Vacuum packaging machines are commonly used in cavity type and external pumping type. China’s vacuum packaging technology was developed in the early 1980s, while vacuum inflatable packaging technology began to be used in the early 1990s.
。 Carbon dioxide can inhibit the activity of molds, spoilage bacteria and other microorganisms. Some foods, such as crisp and fragile food, easily deformed and oily food, food with sharp edges and corners or high hardness, will pierce the vacuum bag. After vacuum inflatable packaging, the inflation pressure in the vacuum bag is greater than the atmospheric pressure outside the packaging bag, which can effectively prevent the food from being crushed and deformed under pressure, and will not affect the appearance of the packaging bag and printing decoration. With the promotion of vacuum bag small packaging and the development of supermarkets, its scope of application will be more and more extensive, and some will gradually replace hard packaging.
