Problems solved by technology

[0002] The existing manufacturing method of plastic-coated composite paper is to use ordinary kraft paper, which is finished by coating the upper surface and the lower surface with plastic, and the plastic-coated composite paper manufactured in this way continues to be processed and produced. The manufactured product (label) will easily cause the same unevenness on the outer surface due to the unevenness of the surface of the kraft paper when it is used. In this way, the paste surface will also be of different heights, thus directly causing the sticking. The contact surface is reduced and the adhesive strength is reduced. At the same time, it also affects the appearance of the appearance

Abstract

A method for making the parting paper by super calender and modified film is characterized by that before original technology including print, extruding-out coating, cooling and cutting, the raw white kraft paper is burnished by super calender for higher smoothness, lustre, compactness and thick uniformity, and the high temp modified high-density polyethylene film is applied on its both surfaces. Its advantages are high appearance quality and high adhesion.

Description

Technical field: [0001] The invention relates to a manufacturing method of plastic-coated composite paper, in particular to a manufacturing method of denatured film overpressure release paper. Background technique: [0002] The existing manufacturing method of plastic-coated composite paper is to use ordinary kraft paper, which is finished by coating the upper surface and the lower surface with plastic, and the plastic-coated composite paper manufactured in this way continues to be processed and produced. The manufactured product (label) will easily cause the same unevenness on the outer surface due to the unevenness of the surface of the kraft paper when it is used. In this way, the paste surface will also be of different heights, thus directly causing the sticking. The reduction of the contact surface and the reduction of the bonding strength also affect the appearance of the surface. Invention content: [0003] The purpose of the present invention is to provide an impr...
