CPP Films (Cast Polypropylene Films)

Cast polypropylene (CPP) films, also known as SUM-CPP Films, are suitable for printing and lamination processes and are widely used as flexible packaging materials across various product categories. CPP films offer excellent mechanical strength, optical clarity, and high puncture and tear resistance. Compared to polyethylene (PE) films, CPP films are glossier, more transparent, and have superior mechanical performance.

Polypropylene is more rigid than polyethylene and offers better resistance to chemicals and organic solvents.

Key Properties of CPP Films

• Excellent heat-sealing performance

• High surface gloss

• Superior mechanical strength

• High melting temperature

• Outstanding puncture and impact resistance

• Better water vapor barrier compared to PE films

• Optional one- or two-sided heat sealability

• Ideal for printing and lamination applications

• High-speed performance on automatic packaging lines

• Strong resistance to cracking, acids, organic solvents, and electrolytes

Common Applications of CPP Films

• Bread bags and bakery product packaging

• Pasta, legumes, and other dry food packaging

• Textile product packaging

• Medical product packaging

• Pet food packaging

• Frozen food packaging

• Films for sterilization and pasteurization

• Lamination and thermal lamination films

• Thermoforming applications
