Abstract
A heat-shrinkable film containing a homogeneous ethylene/alpha-olefin copolymer has a high impact strength and a high free shrink. The film can be a monolayer film or multilayer film, with the homogeneous ethylene/alpha-olefin copolymer present alone or in a blend, and in one or more film layers. The film is especially suited for use in heat-shrinkable bags, which can be used for the packaging of various products, especially meat.
