ABSTRACT:
A laminated construction having differential release characteristics is provided which will yield a self-detackifying adhesive surface upon delamination. The laminate is produced by coating a film of a polymeric material onto one side of a face stock material and then laminating this construction to an adhesive which has been coated onto a release liner. The release liner is removed and the remaining portion of the laminate is affixed to a suitable substrate utilizing the exposed adhesive surface. The polymeric material is chosen so that upon delamination of the face stock from the substrate, it remains affixed to the adhesive coating. This results in a self-detackified adhesive surface on the substrate. The laminate construction is useful for tags, labels, stickers, and the like as well as for sending credit, business, or membership cards on preprinted mailers to ultimate users. Because of the unique self-detackifying surface produced, both the face stock and substrate can be used and further handled or processed by hand or automated equipment.
