POLYOLEFIN LAMINATED PAPER FOR RELEASE PAPER, RELEASE PAPER AND PRESSURE-SENSITIVE ADHESIVE SHEET

摘要

PROBLEM TO BE SOLVED: To provide polyolefin laminated paper for release paper capable of suppressing or preventing the release between a paper base material and a polyolefinic resin layer even if heat treatment is applied.;SOLUTION: The polyolefin laminated paper for the release paper is constituted by forming the polyolefinic resin layer at least on one side of the paper base material by extrusion laminating processing. The polyolefinic resin layer has a multilayered structure and the layer comprising a polyolefinic resin lowest in density in the polyolefinic resin layer having the multilayered structure is positioned on the side of the paper base material. In the polyolefinic resin layer, the layer on the side of the paper base material is a low density polyethylene layer and the layer on the outer surface side of the paper base material is preferably a medium or high density polyethylene layer.;COPYRIGHT: (C)2006,JPO&NCIPI
