摘要： A film comprises a skin layer, a base layer, and an intermediate layer between the skin and base layers. The skin layer comprises polyester. The base layer comprises styrenic block copolymer having a styrene monomer content of at least about 50 wt. %. The intermediate layer comprises: (i) one or more polymers selected from alpha-olefin/cyclic-olefin copolymer and alpha-olefin/vinyl aromatic copolymer and (ii) one or more polymers selected from ethylene/unsaturated ester copolymer and styrenic block copolymer having a styrene monomer content of at most about 50 wt. %. The film has a free shrink at 100° C. in at least one direction of at least about 10%. The film may be useful in shrink sleeve applications.
