CPP - Cast Polypropylene Film

CPP  Characteristics and Applications
Cast Polypropylene Film (abbreviation: CPP) has increased popularity over polyethylene.  Compared to polyethylene, CPP has higher clarity & gloss, better heat resistance, better layflat and planarity.                   


Our CPP films are ISO 9000 and food contact certified. In recent years, as more "ready-to-eat foods" enter the market there is a growing demand for CPP especially if those products are being made through the retort process for the reason that CPP is a critical component in the structure of these laminated packages.  Our newest version of CPP provides an "easy tear" feature not normally seen with CPP films.  This special film allows converters to create retort pouches which are much more consumer friendly for opening. has been selling CPP films to both stationery and packaging markets for 20 years.  We are able to offer converters customized formulations which tailor the film to the particular needs of the applications.

CPP Characteristics
1. Excellent tensile strength, resistance to impact strength and puncture resistance.
2. Excellent toughness and resistance to pinhole and punctures.
3. Good barrier properties to odors and gases (oxygen, nitrogen, carbon dioxide).
4. Excellent resistance to oil, fats and chemical solvent.
5. BOPA has a wide range of usage temperatures (-60℃ to +150℃). The maximum melting point is + 225℃ and BOPA
 has stable mechanical properties in low or high operating temperatures.
6. BOPA is highly hygienic, non-toxic, odorless, and tasteless, which is excellent for packaging of products with
 demanding hygienic requirements.
7. Good transparency, gloss and printing performance, with low haze.
8. BOPA has excellent performance in an environment rich with humidity.


Application of CPP Film
The excellent features of BOPA film make it widely used both in food and non-food industries, such as electrical, insulation, agriculture, food packaging, and medical devices. Very often BOPA is laminated with other materials (PE, EVA, PET, CPP, BOPP, BP, aluminum foil and paper) with the objective of providing a more comprehensive performance. The laminated structure is then utilized for: (1) Food packaging: vacuum refrigerated, vacuum retort and modified atmosphere packages (ham, chicken, sausage and other animal proteins), spice, salty food (pickles), vegetables, aquatic foods, tea, coffee and flavorings. (2) Electrical, insulation and medical: sterile medical devices / medicine, cosmetics, scouring agents, shampoo, integrated circuits and other instruments.
