Analysis of the difference between release paper and release film (4)-film supplier
Improve the adhesion of the aluminized layer and make it resistant to 100℃ cooking. According to the material and use, it can be divided into: silicone oil film / release film-polyester film (PET) PET release film, polyester film, pre-coated Film, light diffusion film, color inkjet film (computer film), electronic industry special printing film, matte film, drawing film, white polyester film, black polyester film, PET/polyester film/PET Mylar. Release paper, also known as silicone oil paper, anti-sticking paper. It is mainly used to isolate sticky objects, such as tape, which generally needs to be peeled off and thrown away during use. Nowadays, the most widely used products are adhesive tapes or carriers of rubberized products. Of course, the applications in the food and medical and health industries will not be described in detail here. Classification of release paper The classification of release paper can be classified into plastic release paper and non-plastic release paper; it can also be classified according to release agent, silicone release paper and non-silicon release paper. There are plastic release papers, because the release agent has certain permeability. If there is no certain barrier, the release agent will penetrate into the paper, resulting in poor curing and excessive use of the release agent (too high cost). factor. Therefore, the paper needs to be coated with plastic (commonly known as laminating). In China, polyethylene (PE) particles are generally used for laminating, and the melt index is required to be around 7. The domestic PE particles generally use 1C7A from Yanshan Petrochemical.
