Lixin Packaging introduces to you the main materials of vacuum bags. Vacuum bags are also called decompression packaging. They are carried out on the principle of atmospheric pressure. The main function of vacuum bags is to remove oxygen and prevent food from rotting. The purpose of preparing vacuum bags is to use an air extractor to remove oxygen in packaging bags and food cells. Remove the process that deprives microorganisms of their living environment.
Carbon dioxide has the effect of inhibiting the activity of microorganisms such as mold, spoilage bacteria, etc. Some foods, such as crispy and fragile foods, are easily deformed and oily. Foods with sharp edges or high hardness can puncture vacuum bags. After vacuum packaging, the air pressure inside the vacuum bag is greater than the atmospheric pressure outside the packaging bag, which can effectively prevent the food from being crushed due to pressure. It will not deform without affecting the appearance and printing decoration of the packaging bag. With the promotion of small packaging of vacuum bags and the development of supermarkets, their scope of application will become more and more extensive and some will gradually replace rigid packaging.
