Technical Datasheet
CPP
CPP is a non-oriented polypropylene film. It offers high gloss, superior transparency, and excellent heat-sealing strength. CPP is often chosen over PE when higher clarity or retort resistance is required.

Engineering Insights
Advantage
Heat Resistance
Retortable grades maintain integrity during high-temp sterilization.
Advantage
Visual Appeal
Offers higher transparency and gloss than standard PE films.
Advantage
Oil Resistance
Excellent for greasy or oily snacks and sauces.
Limitation
Cold Brittleness
Standard CPP can become brittle at freezing temperatures (requires special grades).
Limitation
Stiffness
Lower rigidity than BOPP, usually used as a laminate inner layer.
Practical Usages
Retort Pouches
Essential sealant layer for ready-to-eat meals.
Bread/Bakery
Favored for its high clarity and breathability control.
