LABEL ADHESIVE AND ACTIVATION METHOD FOR POLYMERIC LABEL

摘要

A water activated adhesive system is described that is particularly suited for applying non-paper polymeric labels to surfaces which have low moisture permeability. The adhesive system is characterized by a dry non-tacky surface that becomes tacky in less than one second when contacted with a water-based activator. While it is a water activated adhesive, it is also characterized after aging bonded to a substrate by resistance to adhesive failure during 72 hours of immersion in ice/water mixture. The adhesive is beneficial to allow use of existing paper labeling equipment with polymeric labels.
