CPP Films for Bread Packaging

Polypropylene film (CPP) is produced by polymerizing polypropylene granules. Compared with the widely used polyethylene film, it has several advantages: better transparency, greater moisture resistance, more uniform thickness, higher temperature resistance, etc. Some of the differences between CPP and BOPP are listed below for better understanding:

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

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

3.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.

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