ABSTRACT:
The multi-layer polyolefin shrink film of this invention provides shrink tensions, optical clarity, cuttability, sealability, shrink temperature range, and tear resistance heretofore unobtainable in an oriented, monolayer polyolefin material. The preferred film has three layers in which the core layer comprises a blend of ethylene-vinyl acetate copolymer with ethylene-butylene copolymer and each skin layer comprises ethylene-propylene copolymer.
