CPP Films

 

CPP films are transparent cast polypropylene films designed to offer high performance, great appearance and easy converting for flexible packaging and other applications.

 

CPP films are also produced from a combination of various grades of PP polymer. Various constructions of CPP are available (multi-layer options) which are used to cater to several applications in special packaging, as a sealant layer in conjunction with other plastic substrates for packaging of food products, twist wrap usage in candies, etc.

 

 

Polypropylene film or PP is a low density plastic film. The most important types of PP are cast polypropylene (CPP) and bi-axially oriented polypropylene (BOPP). Cosmo Films offer both these types of PP films. While BOPP is a more commonly known polypropylene film, the use of CPP in the food, pharmaceutical, flower, textiles and several other industries are consistently gaining popularity.

 

Some of the differences between CPP and BOPP are listed below for better understanding:

 

CPP is a soft film like polyethylene, whereas BOPP is a bit stiff and crinkly

 

CPP does not dead-fold well due to its natural living hinge, whereas BOPP has better dead-fold characteristics.

 

CPP can be ultrasonically or thermally sealed without the use of any specialty coatings, whereas BOPP does not heat seal well without the use of specialty heat seal coatings.

 

While BOPP FILMS have better barrier properties than CPP, CPP has better barrier properties than most other polyethylene and PVC films.
