We disclose a composition comprising (i) a monovinylarene-conjugated diene copolymer and (ii) an acrylate terpolymer. The composition can be in the form of a film. We also disclose a container comprising a container structure and a shrink label in contact with the container structure's exterior surface. We also disclose a method of applying a shrink label to a container structure.

Composition for monovinylrenic-based shrink label films

We disclose compositions, comprising (i) from about 25 parts by weight to about 95 parts by weight of a monovinylarene-conjugated diene coupled block copolymer comprising at least one tapered block, having a blocky monovinylarene content of less than 90 wt % of total monovinylarene units, and comprising a terminal monovinylarene block having a molecular weight of less than 60,000 g/mol; and (ii) from about 5 parts by weight to about 75 parts by weight of a monovinylarene-alkyl(meth)acrylate copolymer, comprising (ii-a) monovinylarene units and (ii-b) either alkyl acrylate units, alkyl methacrylate units, or both. The compositions can be used in shrink film or rigid packaging applications.
