Aluminum foil bag refers to a kind of composite bag containing aluminum foil in the composite bag. According to the unique properties of aluminum, it is dry-composited with aluminum and other high barrier materials to make aluminum foil bag products by custom packaging suppliers.
The main film substrates of the composite bag are: outer layer printable film BOPA,BOPET,BOPP inner layer heat sealable film CPPPE, and co-extruded film. AL (aluminum foil) is also one of them, usually as an intermediate layer, these materials are composited into a composite film by glue according to requirements!
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, PA is for increasing physical strength , puncture resistance, AL aluminum foil is to increase barrier properties.
Below is the reason why we should choose foil lined material inside the packaging bags:
