CPP film, namely cast polypropylene film, is a non stretched, non oriented polypropylene film. According to the raw material, it is divided into homopolymer CPP and copolymer CPP, which are divided into general CPP, aluminum plated CPP (WMCPP) and cooking CPP (RCPP) according to function.


The characteristics of the CPP protective film are as follows:

(1) CPP film is high in transparency and good in smoothness

(2) the CPP film has good temperature resistance and easy deformation. It has certain scratch strength and flexibility. The softening point is about 140 degrees.

(3) CPP film has good hand feel, shading, thermal sealing, and easy to resist adhesion.

(4) CPP film has excellent moisture and moisture resistance, and has a certain resistance to oxygen and oil.


CPP film is non-toxic, tasteless, odorless and hygienic, and its density is 0.92g/ cm3.

Because the CPP protective film has the high temperature resistant property that PE substrate film can not bear, it is especially suitable for IMD IML and other electronic manufacturing processes.


CPP protective film is mainly suitable for photoelectric film, diffuser, light guide plate, film, prism, especially suitable for ITO film covering film, and IMD, IML and other electronic manufacturing process.
