TECHNIQUES FOR LABELING WITH LABELS EMPLOYING AN ACTIVATED HYDROPHILIC ADHESIVE

摘要

The invention provides a method for fastening a precoated paper label to a glass, plastic or metal container or surface by means of a water based composition containing at least 30% by dry weight of animal glue or natural or synthetic polymers that can be activated into an adhesive by the following steps: (a) applying a layer of a hydrophilic solid material based on at least 30% by weight on protein from animal renderings or natural or synthetic polymers to a paper label substrate to form a hydrophilic layer that acts as an adhesive layer when activated with an aqueous medium; (b) applying a minimal amount of water or water containing a cross -linking agent to the activatable hydrophilic layer to activate said activatable hydrophilic layer into an adhesive and form a fastenable paper label; (c) fastening the fastenable paper label to a glass, plastic or metal container or surface; and (d) allowing said the paper label to dry on the glass, plastic or metal container or surface.
