Release Liner or Release Film is siliconized on PE, PET, PP or other type plastic films or papers, that enables to possess release effectiveness. It is usually used as the protective film of self-adhesive products, and directly peeled off from the self-adhesive products when used.
YK hydrophilic PE Release Film is an upgraded version of ordinary hydrophilic Release Film. YK hydrophilic PE Release Film overcomes the shortcomings of ordinary hydrophilic PE Release Film, such as low temperature resistance and low Subsequent adhesion rate. High temperature resistance, high residual connection and low silicon rotation; At the same time, in the competition with PET release film, it can solve the wrinkles formed by the use of PET release film coiled material on the surface of the coiled material after rolling, avoid the leakage caused by the possible hollowing, and solve the problem that the PET release film is difficult to tear in summer. At the same time, YK hydrophilic PE Subsequent adhesion rate is a polyolefin material, which can be recycled and reused. It can solve the problem that the PET isolation film cannot be recycled and difficult to deal with after use, which is more environmentally friendly.
