CPP film is produced through a casting process and features high stiffness, good moisture and odor barrier properties, and relatively low cost. Its main classifications include:
General-purpose CPP: Commonly used for composite packaging of clothing, textiles, and general merchandise.
Metallized-grade CPP: Suitable for metallization, used in high-barrier and decorative packaging (e.g., snacks, tea).
Retort-grade CPP (RCPP): Heat-resistant (up to 140°C), suitable for high-temperature applications such as retort pouches and sterile packaging.
Additionally, CPP film is expanding into emerging areas such as anti-fog film, synthetic paper labels, and stand-up pouches, meeting diverse packaging needs.
