Title:
BARRIER LAMINATE HAVING EXCELLENT MOISTURE AND GAS BARRIER PROPERTIES, AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2020/013458
Kind Code:
A1
Abstract:
The present invention relates to a method for producing a high barrier substrate used for packaging, in which permeation of a barrier material through paper is suppressed through a sizing or coating process on the surface of the paper, and the density and the smoothness of the paper are increased through a calendering process, thereby making it possible to directly coat a material exhibiting barrier properties onto a paper substrate, so that a barrier layer may, as a single layer, simultaneously block gas and moisture.
