Retort Roll Film

Product information description:

PET/AL/PA/RCPP  PET/PA/RCPP

Retort roll film is engineered to withstand the high-temperature, high-pressure sterilization conditions of retort processing while maintaining structural integrity, barrier performance, and seal strength throughout the sterilization cycle. Constructions are specified based on the sterilization temperature, target shelf life, and product characteristics — typical structures combine polyester, nylon, and retort-grade seal layers, with or without aluminum foil depending on whether transparency or total barrier is required.

The retort-grade inner seal layer is formulated specifically for high-temperature sterilization applications, providing stable heat-seal strength before, during, and after the cycle without delamination or seal failure under pressurized steam or hot-water retort conditions. The nylon layer contributes puncture resistance and flex-crack resistance critical for maintaining package integrity during the retort process and subsequent distribution.

Foil-containing structures deliver total barrier protection against oxygen, moisture, and light — essential for products requiring 12 to 24 months of ambient shelf life. Transparent structures are available for applications where product visibility is commercially important and moderate barrier is sufficient.

This film is validated for use on standard retort pouch pouching lines and is compatible with both flat-pouch and stand-up pouch formats. Regulatory compliance documentation for food contact applications is available upon request.
