A PRESSURE SENSITIVE ADHESIVE SHEET WITH AIR-ELIMINABLE CHANNELS AND ITS MANUFACTURING METHOD

摘要

PURPOSE: A pressure sensitive adhesive sheet is provided to enable the smooth discharge of air between the adhered surface of an object and an adhesive layer by forming air-discharge channels on a base film. CONSTITUTION: A pressure sensitive adhesive sheet includes an adhesive layer(2) with an embossed pattern on the surface of a base film through a screen printing method. An intaglio between the adhesive layers has air discharge channels(W) with the width of 10~6 micron. The gap between the discharge channels is 2~4 mm. A release paper is installed on the surface of the adhesive layer.
