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. 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. Product description: 1. air barrier performance, oxidation resistance, waterproof, moisture-proof. 2. High mechanical properties, high blasting performance, strong anti-puncture tear resistance. 3. High temperature (121 ℃), low temperature (-50 ℃), oil, Paul Hong good performance. 4. Non-toxic, tasteless, with food, pharmaceutical packaging hygiene standards. 5. The heat-sealing performance, flexibility, good barrier properties. Vacuum bag structure is generally: PA / PE or PA / CPP PET / PE or PET / CPP also has three, four, in order to increase the texture of the material properties, PET / PA / PE PET / AL / CPP PA / AL / CPP PET / PA / AL / CPP
