Aluminum foil bag refers to a kind of composite bag containing aluminum foil in the composite bag. The aluminum foil bag is opaque, but the composite bag is not necessarily. The sealing machine is made by dry-compositing aluminum and other high-barrier materials according to the unique properties of aluminum. Made into aluminum foil bag products.
The main film substrates of the composite bag are: outer layer printable film BOPABOPETBOPP inner layer heat sealable film CPPPE, and coextruded film. AL (aluminum foil) is also one of them, usually as an intermediate layer of these materials. According to the requirements, the plastic barrel sealing machine is compounded into a composite film by glue!
The common structure of aluminum foil bag is: PET / PA / PE or CPPPET / AL / CPPPA / AL / CPPPET / PA0 / AL / CPP basic features are: PE is suitable for low temperature use, CPP is suitable for high temperature cooking so that PA is to increase Physical strength, puncture resistance, AL aluminum foil is to increase the barrier performance, milk tea sealing machine is generally used as an intermediate layer PET, increasing mechanical strength, stiff. The toy blister sealing machine is then combined according to the needs, various properties, and also transparent, in order to increase the barrier property.
Can use water resistant PVA high barrier coating.
1. The aluminum foil bag has metallic luster. The filling and sealing machine has high reflection ability to heat and light, and the printing color of the aluminum foil bag is more beautiful and bright.
2. The aluminum foil bag has good insulation performance, strong protection performance, and has the characteristics of non-breathable body and water vapor. The plastic sealing machine can effectively prevent moisture absorption and gasification of the contents, is not easily damaged by bacteria and insects, and has shape stability. not affected by humidity changes.
3, Using shielding or elution for partial aluminizing, can get any pattern and any transparent window, aluminum foil sealing machine so that customers can see the contents of the package, this is a major advancement in the production technology of aluminum foil bags, and also a foil bag Notable features.
