The multi-layer composite or composite aluminum foil bag refers to the packaging material formed by the composite of two or more layers of films, which can be not only plastic films, but also aluminum foil metal materials, and paper, etc.
The essential difference between the composite bag and the single-layer bag is that the single-layer bag is made of a single-layer material, and the composite bag is made of two or more layers of materials. Such as single-layer OPP bag, single-layer PE bag and composite OPP/PE bag, composite OPP/CPP bag, etc.,
Composite aluminum foil bag packaging bag requires higher technical process and more advanced packaging machine
Because the single-layer packaging bag is a single-layer material, and some materials are not conducive to the printing of the packaging bag, most of the single-layer bags are transparent.
Because of the single layer, less material consumption and much cheaper price, it is widely used in clothing packaging bags, electronic product packaging bags and other fields.
The composite aluminum foil bag packaging bag is multi-layered, and the printing technicians are required to be familiar with the characteristics of the relevant materials, and the bag types of the composite bag are various, requiring a variety of different packaging machines.
The multi-layer material of the composite bag is compounded, and the material cost increases, coupled with the cost of composite glue, labor cost, bag making cost, etc., the price of the aluminum foil bag of the composite bag is much higher than that of the single-layer bag. Multi-layer lamination uses more than two kinds of materials for the production of aluminum foil bag packaging bags, which can prevent moisture, increase strength, block light, etc., and the products placed inside will be perfectly protected.
