ABSTRACT:
A multilayer adhesive construction and method for production of said construction are provided. The construction comprises a facestock, a barrier layer on the facestock, and an adhesive layer on the barrier layer. The barrier layer comprises a pressure-sensitive adhesive which inhibits the migration of mobile species such as oils, resins, tackifiers, or plasticizers from the adhesive layer into the facestock or from the facestock into the adhesive layer. This migration of mobile ingredients often manifests itself as swelling or hardening of the facestock which, in turn, leads to wrinkling of the adhesive construction and general loss of adhesion. The multilayer adhesive construction of the invention thus improves adhesion and the appearance of the label by inhibiting wrinkling and/or staining.
