The main role of vacuum packaging is to remove oxygen, in order to help prevent food spoilage, the principle is relatively simple, because the spoilage of food is mainly caused by microbial activities, and most microorganisms (such as mold and yeast) survival needs oxygen, and the vacuum packaging is the use of this principle, the packaging bag and food cells in the oxygen pumping out, so that microorganisms lose the environment of survival. The experimental results show that when the oxygen concentration in the bag is Bing, the growth and propagation rate of microorganism drops sharply, and the oxygen concentration ≤ 0.5%, most microorganisms will be inhibited to stop breeding. (Note: Vacuum packaging can not inhibit the reproduction of anaerobic bacteria and enzyme-induced food spoilage and discoloration, and therefore need to be combined with other ancillary methods, such as refrigeration, frozen, dehydration, high-temperature sterilization, irradiation sterilization, microwave sterilization, salt pickling and so on. ）
Vacuum Inflatable Packaging In addition to the vacuum packaging has the function of oxygen quality, the main also has the effect of pressure, gas, preservation and so on, can more effectively keep the original color, fragrance, taste, shape and nutritional value.
