摘要: An improved process for coating a pressure sensitive adhesive upon a differential-release-type substrate and the products produced thereby. The coating procedure involves using a solvent-free hot-melt adhesive coating system and a short period of exposure to the environment of the web being processed between the time the web is coated with adhesive and spooled for packaging.
