Laminated bag


Composite bag is a packaging product made of multiple layers of different materials through the composite process, combining the advantages of each layer of materials, widely used in food, medicine, industry and other fields. The following are its core points:

Base structure

Composed of 2-4 layers of materials (e.g. plastic film, aluminum foil, nylon, etc.), typical structures include PET/AL/PE (polyester/aluminum foil/polyethylene), PA/PE (nylon/polyethylene), etc., which are realized by hot melt or adhesive. Interlayer bonding.

Four-layer composite structures (e.g. PET/NY/AL/PE) can further improve barrier and load-bearing capacity, and are suitable for high-protection scenarios.

Core Functions

Moisture, oxidation, light barrier, puncture resistance, heat sealability and flexibility.
