PET Release Film
PET release film is also called peeling film, separation film, backing paper, backing plate, silicone oil film. Slip film is a cell phone sticker film torn this layer, it surface silicone oil treatment, reduce adhesion, making the surface adhesion becomes smaller, so that the ink or adhesive products better separation.
Product Characteristics:
High transparency, high surface cleanliness, good flatness, good thermal stability
Main Applications:
Widely used in the fields of silicone coating, release, protection of electronic and electrical appliances, adhesive tapes and so on.
Characteristics of Release Film
- Suitable adhesion to different material surfaces.
- Good adhesion to the protected material, no peeling or warping of the release film during material handling and processing.
- The substrate and pressure sensitive adhesive have excellent mechanical properties to meet various secondary processing requirements.
- Graphite calendering release film is inert to the surface of the protected material, does not react with the surface, does not corrode, does not pollute the material surface.
- Graphite calendered release film has good weather resistance, processability, little change in peeling force (bonding force) after several days or long posting, easy to peel off.
