Abstract
A polyolefin shrink film having high shrinkage and low shrink force. The film has a core layer formed from a polymer of ethylene with a melting point of greater than 100° C., outer layers of a homopolymer of ethylene or propylene or an ethylene/alpha-olefin copolymer. The film is not irradiated. The film may be used in the packaging of articles subject to breakage, distortion or deformation if packaged in shrink films with higher shrink force.
