Main products: aluminum foil bag, vacuum bag, shielding bags, aluminum bags, board vacuum bags, cooking food vacuum bag, nylon vacuum bag, anti-static metal bags and other packaging materials. Kunshan Chi Shing Packaging Materials Co., Ltd., specializes in producing all kinds of bags. Main products are cooking vacuum bag, anti-electromagnetic interference vacuum, environmental protection vacuum, vacuum aluminum foil bags, shielding vacuum, vacuum printing, food vacuum, vacuum grid, PE nylon vacuum bag, PE bags . Vacuum nylon bags are generally complex, that is one, two or more of the base film (heat sealing PE film, CPP, BOPP) and nylon (airtight better) or PET film dedicated by adhesive (chemical products) After laminating machine complex deposition, and then cut bags made of. After vacuum sealing performance is optimal. Air barrier performance, oxidation resistance, waterproof, moisture and strong mechanical properties, high blasting performance, strong anti-puncture tear resistance, high temperature (121 ℃), low temperature (-50 ℃). Good heat sealing properties, good transparency. Non-toxic, tasteless, in line with national standards. Also known as decompression vacuum packaging, is based on the principle of atmospheric pressure, the main role of the vacuum bag is oxygen, in order to help prevent food spoilage or deterioration. Vacuum packaging is to package food bags and oxygen within the cell by pumping deprived, so that microbial processes lose "living environment". Vacuum also prevents oxidation of food, so the food does not taste, deterioration to reduce the loss of vitamin A and C. Vacuum bagged product, taking the air bag, to maintain the purity of the original flavor of food, it has a metal barrier, but also to make the metal vulnerable to acids, alkalis, and other corrosive sulfur insufficient transparency both glass, and overcome the shortcomings of the fragile glass, both paper portability, but also to make the paper easy to damp the defect, but has all the functions of the various plastic films. Used in a variety of raw food cooked food preservation.
