VERFAHREN ZUR HERSTELLUNG von VERBUNDMATERIAL MIT GASBARRIERE AUF BASIS VON STÄRKE und VERPACKUNGSBEHÄLTER

摘要

The present invention provides a method for producing a packaging laminate having excellent gas barrier properties. The method involves applying a solution or dispersion of starch or starch derivative to a surface of a substrate of paper or paperboard, and applying a layer of plastic to said starch or starch derivative so as to modify the properties of same such that the starch or starch derivative provides a gas barrier property.
