by:Supouches Packaging     2022-07-21
Oxygen barrier aluminum foil bag refers to a type of composite bag containing aluminum foil. According to the unique properties of aluminum, the sealing machine uses aluminum and other high-barrier materials to dry compound and make oxygen barrier aluminum foil bag products. Next, let's take a look at how the strong barrier properties of the oxygen barrier aluminum foil bag are obtained in terms of oxygen barrier and moisture barrier. PE is suitable for low temperature use, CPP is suitable for high temperature cooking, PA is to increase physical strength and puncture resistance, and AL aluminum foil is to increase barrier performance. The toy blister sealing machine and then according to the needs, combinations, various properties, there are also transparent, in order to increase the barrier performance, the water-resistant PVA high-barrier coating is used to block oxygen and moisture. 1. The oxygen-insulating aluminum foil bag has good insulation performance, strong protection performance, and has the characteristics of airtight gas and water vapor. Therefore, the blister sealing machine can effectively prevent moisture absorption and vaporization of the contents, and is not easy to be invaded by bacteria and insects. Good stability, not affected by humidity changes. 2. The oxygen barrier aluminum foil bag has a metallic luster, the filling and sealing machine has a high reflectivity to heat and light, and the printing color of the oxygen barrier aluminum foil bag is more beautiful and brighter. 3. Partial aluminum plating by shielding or elution can obtain any pattern and any transparent window, and the aluminum foil sealing machine can allow customers to see the contents of the package. This is a major progress in the production technology of oxygen-isolated aluminum foil bags A distinctive feature of foil bags.
