Foil aluminum bags have been widely used in food, medicine, aerospace and other fields due to their light weight, good airtightness, and good coverage. Mainly widely used in moisture-proof packaging of powders and moisture-absorbing items (such as food, medicine, seeds, etc.) made. The main features of foil aluminum bags are excellent barrier properties, soft and foldable, high mechanical strength, oil resistance and corrosion resistance and excellent heat sealing performance.

With the continuous improvement of the production process of foil aluminum bags, the advantages of foil aluminum bags are becoming more and more obvious, which opens up a new incremental space for the application of aluminum foil in the packaging industry. Compared with developed countries such as Europe and the United States, China's per capita aluminum consumption Still low.

Foil aluminum bags are made of high temperature resistant plastic or nylon layer and aluminum plastic composite film with high temperature resistant adhesive, which can withstand high temperature sterilization treatment of 120~150 degrees, and are used for sauce, paste, solid cooking food packaging and space food packaging .

In foil aluminum bags, the aluminum layers or between the aluminum layers and the heat-sealing plastic layer are directly bonded without applying adhesive. The obtained flexible packaging composite material has no solvent residue problem, is environmentally friendly and hygienic, and has good adhesion (composite composite material). ) high intensity.
