Zusammenfassung:	A heat shrink film comprising a core layer having an upper and lower surface and comprising a blend of (A) less than 40% of an alpha-olefin copolymer that is a copolymer of ethylene or propylene with an alpha-olefin and (B) a polyolefin copolymer, and (C) an olefin homopolymer; a skin layer on the upper surface of the core layer; and a skin layer on the lower surface of the core layer. The film exhibits excellent shrinkage and is suitable as a shrink film to encapsulate a wide variety of articles including, for example, batteries.
