Release paper is made from wood fibre paper and is first laminated with a polyethylene film (PE) and then coated with a thin layer of non-stick silicone. It is divided into various categories, including single-sided silicone-coated release paper and double-sided silicone-coated release paper. Due to its high resistance to adhesive materials, it provides excellent release of sticky materials such as adhesives.

Detailed classification of release papers Release papers can be classified according to plastic release paper and non-plastic release paper; it can also be classified according to the release agent as silicone release paper and non-silicone release paper. Plastic release paper, because the release agent has a certain permeability, if there is no certain barrier, the release agent will penetrate into the paper, resulting in poor curing and the use of a large amount of release agent (too high cost) and many other undesirable factors. So the paper needs to be coated with plastic processing (commonly known as lamination), domestic general use of polyethylene (PE) particles for lamination, requiring a melt index of about 7, domestic PE particles are generally used Yanshan Petrochemical 1C 7A. divided into single plastic release papers and double plastic release papers; no plastic release papers, mainly Grassian, CCK and other release papers by special treatment . 1.
