PET/AL/CPP High-Temperature Retort Pouch Film

About PET/AL/CPP

PET/AL/CPP laminated film is a high-performance multi-layer aluminium laminated packaging material specifically designed for high-temperature retort pouch applications. This structure combines PET (polyester) for strength, aluminium foil (AL) for barrier protection, and CPP (cast polypropylene) for heat sealing and thermal resistance.

As a professional retort pouch film manufacturer and supplier, we provide high-quality aluminium laminated films capable of withstanding sterilization temperatures up to 121–135°C. These materials are widely used in ready-to-eat food packaging, sauces, and vacuum-packed products, ensuring extended shelf life and product safety.
