RELEASE FILM BONDED DOUBLE-SIDED ADHESIVE SHEET AND PROCESS FOR PRODUCING THE SAME

摘要

PURPOSE: A releasable film bonded double-sided adhesive sheet and a manufacturing method thereof are provided to prevent interruption of solidification reaction due to ultraviolet irradiation even if the thickness of the adhesive layer is thick. CONSTITUTION: A releasable film bonded double-sided adhesive sheet is formed by welding releasable films on both sides of the double coated sheet which includes a hardening material of UV-curable adhesive. The releasable film has a releasable layer on the surface of the junction of the base film which includes a resin. A resin which constitutes one or more of the base films among the releasable films is a polyolefin resin. The polyolefin resin which constitutes the base film is a polypropylene based resin.
