How Is CPP Different From BOPP?
2024-03-14 15:56Both BOPP (biaxially oriented polypropylene) and CPP are polypropylene films, and there’s no doubt that BOPP is more popular than CPP. However, the softness and flexibility of CPP films are the unique features that set them apart. The heat sealing properties of CPP films are also better than BOPP films, which require special coatings for heat sealing. While BOPP and BOPA films demonstrate better barrier properties, CPP films exhibit higher impact and tear resistance, better heat-sealing properties, and improved performance at cold temperatures.
What’s more, cast propylene films have high transparency and can easily be printed, making them perfect for use in food packaging. From a commercial standpoint, CPP films are relatively inexpensive and have a higher yield per unit area.
