RELEASE LINER AND PRESSURE-SENSITIVE ADHESIVE SHEET

摘要

A release liner having a multilayer structure composed of at least three layers, characterized in that one of the surface layers is a layer made of high-density polyethylene, the other is a layer made of low-density polyethylene, and the liner has an interlayer comprising low-density polyethylene as the only resin component. Also provided is a pressure-sensitive adhesive sheet comprising the release liner and at least one pressure-sensitive adhesive layer, characterized in that the peel force between the release liner and the pressure-sensitive adhesive layer, X (N/mm), and the rigidity of the release liner [(Young's modulus of the release liner)x(thickness)³], Y (N.mm), satisfy the relationships 04+0.1. The release liner and the pressure-sensitive adhesive sheet have excellent releasability. Even when stored in a curved state, the adhesive sheet suffers no liner lifting. The release liner has excellent suitability for recycling.
