ABSTRACT:
A heat-shrinkable, biaxially-oriented, multilayer film has a first layer comprising an ethylene/alpha-olefin copolymer having a major DSC peak of less than 105.degree. C. The multilayer film has a free shrink, at 185.degree. F., of at least 80 percent, and all layers of the multilayer film are shrink-compatible with respect to one another. Preferably, the multilayer film has a second layer which is an oxygen barrier layer, and preferably both of the outer film layers are grease-resistant. Furthermore, the invention includes a bag comprising the multilayer film, as well as a packaged product having a package comprising the multilayer film.
