Abstract
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 adhesive composition by the following steps: (a) applying a layer of a hydrophilic solid material to a polymeric label to form a hydrophilic layer; (b) applying water or a water based adhesive to the hydrophilic layer to form a fastenable polymeric label; (c) fastening the fastenable polymeric label to a glass, plastic or metal container or surface; and (d) allowing said the polymeric label to dry on the glass, plastic or metal container or surface.
Claims21
A method for fastening, a precut polymeric label or a polymeric label from roll sheet stock that is cut by machine to label size, to a glass, plastic or metal container or to a glass, metal or plastic surface in post mold labeling operations using wet applied water based labeling equipment used for the application of paper labels and a water based adhesive composition, said method comprising:
- (a) applying a layer of a hydrophilic solid material to said polymeric label to form a hydrophilic layer on said polymeric label which has the property of dry tack for handling before labeling;
- (b) applying a water based adhesive to said hydrophilic layer to form a fastenable polymeric label;
- (c) fastening said fastenable polymeric label to a glass, plastic or metal container using wet applied water based labeling equipment used for the application of paper labels;
- and
- (d) allowing said polymeric label to dry on said glass, plastic or metal container.
A method for fastening, a precut polymeric label or a polymeric label from roll sheet stock that is cut by machine to label size, to a glass, plastic or metal container or to a glass, metal or plastic surface by means of a water based adhesive composition, said method consisting essentially of the steps of:
- (a) applying a layer of a hydrophilic solid material to said polymeric label to form a hydrophilic layer on said polymeric label which has the property of dry tack for handling before labeling;
- (b) applying a water based adhesive, which contains a synthetic resin dispersion to form a fastenable polymeric label;
- (c) fastening said fastenable polymeric label to a glass, plastic or metal container using fastenable polymeric label to glass, plastic or metal container using wet applied water based labeling equipment used for the application of paper labels;
- and
- (d) allowing said polymeric label to dry on said glass, plastic or metal container.
A method for fastening a polymeric label made from a polymer selected from the group consisting of polypropylene, high density polyethylene and polyethylene terephthalated to a glass, plastic or metal container or to a glass, metal or plastic surface by means of a water based adhesive composition, said method consisting essentially of the steps of:
- (a) applying a layer of a hydrophilic solid material to said polymeric label to form a hydrophilic layer on said polymeric label which has the property of dry tack before labeling;
- (b) applying a water based adhesive to form a fastenable polymeric label;
- (c) fastening said fastenable polymeric label to a glass, plastic or metal container using wet applied water based labeling equipment used for the application of paper labels;
- and
- (d) allowing said polymeric label to dry on said glass, plastic or metal container.
