PRODUCTION OF BOTH GLASSINE PAPER AND RELEASE PAPER

摘要

PROBLEM TO BE SOLVED: To produce a sheet of glassine paper, having good disintegrating properties usable as a raw material for recycled paper when used as a sheet of base paper for release paper of a tacky sheet and providing the release paper without any problem in sensing a label position in a labeler having a transmitting type positional sensor. SOLUTION: A chemical pulp having 130-210ml freeness expressed in terms of Canadian standard freeness(CSF) is used as a main raw material and the threading treatment of a sheet of base paper in a semidried state is carried out with a nip having 10-50kg/cm linear pressure formed by two rolls. The resultant sheet of paper is then dried in the method for producing a sheet of glassine paper comprising coating a sheet of base paper with an aqueous solution of a polyvinyl alcoholic resin in a coating part installed in the interior of a paper machine, then carrying out compressing treatment and finishing the paper.
