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. Inflatable packaging vacuum is drawn in the vacuum, and then filled with nitrogen, carbon dioxide and other gases. Nitrogen is an inert gas, from the filling, so that the vacuum bag to maintain a positive pressure to prevent the bag outside air into the bag of food play a protective role. Carbon dioxide inhibit mold, spoilage bacteria and other microbial activity role. Some, such as crispy or crunchy food, deformation take the oil in food, there are sharp edges or high hardness can puncture the vacuum bag and other food, after filling the vacuum packaging, vacuum bag inflatable bag outside pressures greater than atmospheric pressure, can effectively prevent food compression crushing, deformation, and does not affect the appearance of bags and printing and decorating. With the promotion and development of small supermarket vacuum packed, its scope will be more widespread, some will gradually replace the rigid packaging.
