Release liner and pressure-sensitive adhesive sheet |
摘要 |
<p>Provided is a release liner formed of a plastic film having a laminated structure of at least three layers, described specifically, as two surface layers, (A) a release functioning layer composed of a polyethylene film having a density of 0.88 to 0.92 g/cm<3> and a melt index not greater than 10 g/10 minutes and (B) a surface film layer having a thermal linear expansion coefficient similar to that of said release functioning layer and, as an intermediate layer, (C) a reinforcement layer having a melting point not less than 120 DEG C. By forming a pressure-sensitive adhesive layer on the surface of the release functioning layer (A) of the above-described release liner, a pressure-sensitive adhesive sheet can be obtained. The release liner exhibits good release function without using a silicone-base releasing agent and has heat resistance sufficient for not causing deformation such as curl even when heat is applied to the liner. <IMAGE></p> |
