<p>The invention provides a method for fastening a polymeric label to a glass, plastic, or metal container or surface by means of a water based composition containing ac least 30% by dry weight of animal glu; that is 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 to a polymeric label to form a hydrophilic layer that acts as an adhesive layer when activated with an aqueous medium; (b) applying a low deposition of water, a water based adhesive, water containing a cross-linking agent or an adhesive containing a cross-linking agent to the activatable hydrophilic layer sufficient enough to activate it into an adhesive and form a fastenable polymeric label; (c) fastening the fastenable polymeric label to a glass, plastic or metal container or surface; 0nd (d) allowing the polymeric label to dry on the glass, plastic or metal container or surface.</p> |
