摘要: A heat shrinkable label comprises (A) a heat shrinkable film comprising at least one thermoplastic polymer, and (B) a curable adhesive comprising (1) at least one urethane (meth)acrylate resin having an average of about 1 to about 1.6 (meth)acrylate groups per resin molecule, (2) at least one tackifier, and (3) at least one photoinitiator, where the film has an ultimate shrinkage at 135° C. of at least 15%, and the adhesive has sufficient precure tack, wherein the loop tack of the uncured adhesive is at least 4.3 g/cm2. The heat shrinkable label is useful in high-speed industrial processes such as beverage container labeling.
