Aluminum foil packaging bag refers to a kind of composite bag containing
aluminum foil. According to the unique properties of aluminum, the sealing machine uses aluminum and other high barrier materials to make aluminum foil packaging bag products after dry compounding.

The common structures of aluminum foil packaging bags are: PET / PA / PE or cpppet / Al / cpppa / Al / cpppet / PA0 / Al / CPP
PE is suitable for low temperature use, CPP is suitable for high temperature cooking use, PA is to increase the physical strength, puncture resistance, and Al aluminum foil is to increase the barrier performance, milk tea sealing machine is generally used as the middle layer pet to increase the mechanical strength, crisp. The toy blister sealer then according to the demand, combination, all kinds of performance, also have transparent, plastic bag factory in order to increase the barrier performance using water-resistant PVA high barrier coating, oxygen resistance and moisture resistance.
1、 The
aluminum foil packaging bag has good insulation performance, strong protection performance, and the characteristics of impermeable gas and moisture. Therefore, the blister sealer can effectively prevent the moisture absorption and gasification of the contents, is not vulnerable to viruses and insects, has good shape stability, and is not affected by the change of humidity.
2、 The
aluminum foil packaging bag has a metallic luster, the filling and sealing machine has a higher reflection of heat and light, and the printing color of the aluminum foil bag is more exquisite and bright.
3、 Using shielding or elution for partial aluminum plating, the plastic bag factory can obtain any pattern and any transparent window, and the
aluminum foill sealing machine enables customers to see the contents of the package, which is a significant progress in the production technology of
aluminum foil packaging bags, and also a prominent feature of aluminum foil packaging bags.
