CPP/AL/PET aluminum foil composite packaging film is a multi-layer film that is widely used in the packaging industry due to its excellent barrier properties, durability and versatility. The structure usually consists of three layers: CPP, aluminum foil and PET.

1. CPP (cast polypropylene)
As the outer layer, providing strength and flexibility.
Good transparency and gloss.
Excellent sealing and moisture resistance.
High tensile strength and durability.
2. Aluminum foil
As a barrier layer.
Provides complete barrier to light, oxygen and moisture.
Protects sensitive contents from environmental factors and extends shelf life.
Increases thermal stability, making it suitable for heat-sealed products.
3. PET (polyethylene terephthalate)
Used as a protective inner layer.
High strength and dimensional stability.
Excellent chemical and moisture resistance.
Good clarity and printability.

Advantages of CPP/AL/PET Composite Film
Barrier Properties: The combination of aluminum foil with CPP and PET has excellent barrier properties, making it ideal for packaging food, pharmaceuticals, and other sensitive products.
Thermal Stability: The film can withstand a wide range of temperatures, making it suitable for both hot fill and cold fill applications.
Customizability: Available in a variety of thicknesses and surface colors, it can be customized to specific packaging requirements.
