CPP or cast polypropylene film is a multilayer polypropylene film with co-polymer and homo-polymer. It is used as a heat seal layer along with BOPP or polyester film in a laminate for packing of food articles. CPP films have been known in the packaging field to be the more elegant brother of polyethylene film, with higher gloss, greater transparency and better heat resistance.

CPP films have higher gloss and transparency, higher strength, superior barrier properties and excellent sealing strength. They are available with a polished or embossed surface, gloss or matte finish, stiff or flexible, clear or colored, or in a combination thereof. They are versatile and the most cost effective films.

Film Storage and Handling
Although CPP films are suitable for use within 4 months from the date of delivery, it is advisable to rotate film stock. It is recommended that dry conditions at temperatures below 35 degree C are used for storage of these films, otherwise a reduction in surface treatment level may be experienced. On account of the elastic memory of thermoplastic film, a prolonged period of storage may cause problems of profile and blocking. The film should be kept in its original wrapping until it is used and should be kept at room temperature 24 hours prior to processing. Films are very sensitive and any damage or load on the CPP roll may cause blocking.
