ABSTRACT:
A multi-layer packaging film comprising layers having varying degrees of cross-linking when subjected to electron beam (EB) radiation. The outer layer has a high degree of cross-linking to improve the adhesion, strength, toughness and heat resistance of the film and the inner layer has a low degree of cross-linking to improve the sealability. Bags made from the multiple layer films are especially useful for shrink packaging, and particularly for shrink packaging of meats having large cavities.
