CPP/AL/PET Aluminum Foil Laminated Packaging Film Three Layers
CPP/AL/PET aluminum foil composite packaging film is a multi-layer film widely used in the packaging industry due to its excellent barrier properties, durability, and versatility. The structure consists of three specialized layers working together to provide optimal protection.
Layer Structure & Properties
CPP (Cast Polypropylene) - Outer Layer
- Provides exceptional strength and flexibility
- Offers good transparency and gloss
- Excellent sealing and moisture resistance
- High tensile strength and durability
Aluminum Foil - Barrier Layer
- Provides complete barrier to light, oxygen, and moisture
- Protects sensitive contents from environmental factors
- Extends product shelf life significantly
- Increases thermal stability for heat-sealed products
PET (Polyethylene Terephthalate) - Protective Inner Layer
- High strength and dimensional stability
- Excellent chemical and moisture resistance
- Good clarity and printability
Key Advantages
- Superior Barrier Properties: Ideal for food, pharmaceuticals, and sensitive product packaging
- Thermal Stability: Withstands wide temperature ranges for hot and cold fill applications
