ABSTRACT:
A thermoplastic film is provided which is especially suited for use in stretch/cling applications such as, for example, the bundling, packaging and unitizing of foods and other goods. The film comprises a cling layer comprising a polymer of at least ethylene and acrylate, preferably without a tackifying additive. The film further comprises a slip layer comprising a polyolefin preferably including an anticling (slip and/or antiblock) additive. Preferred polyolefins include linear low density polyethylene and polypropylene.
