摘要:
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 (i) a non-cling polymer of at least ethylene and acrylate or vinyl acetate, blended with (ii) a compatible, non-migratory tackifier. The film may further comprise a non-cling layer comprising a polyolefin essentially free of tackifier, with or without an anticling (slip and/or antiblock) additive. Preferred polyolefins include linear low density polyethylene and polypropylene.
