pe protective film is generally divided into two kinds: one is oil adhesive free base paper; The other is the release of water glue base paper.
Both of the above are made up of three parts: release paper coated with silicone, glue (oil glue or water glue), and PVC plastic mask.
Adhesive composite type adhesive film, due to different uses generally not called pe protective film (also used for protective effect), mainly used in advertising production, such as computer engraving, the effect of the adhesive is the engraved text, pattern is not easy to deformation, suitable for long-term Posting is not easy to warping, fall off.

pe protective film can be summarized as three points:
1, the first requirement is not degumming, after the completion of glass processing, remove the maintenance film, the surface of the processed glass products can not remain a little glue and traces, in order to adhere to the bright and beautiful products.
2, good strength and toughness, refers to the mask can withstand the impact of injection of emery up to 6~8 kg, otherwise it will breakdown the maintenance film, break the processed object.
3, with appropriate viscosity, it means that the mask can not only be affixed, firmly posted on the glass body being maintained, but also can be smoothly removed after processing, so as not to increase unnecessary trouble due to brittle, thin fracture, tear. 4, maintenance film color and specifications, can be customized according to the user's requirements, commonly used color is white, light yellow. Length in meters, according to user requirements. The quality of maintenance film directly affects the working time and product quality.
