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 polyethylene, preferably low density polyethylene (LLDPE) and a compatible tackifier. The LLDPE has a density of from about 0.87 to about 0.92 g/cc, a melt index of from about 1 to about 30 dg/min and a ratio of weight average molecular weight to number average molecular weight (M.sub.w /M.sub.n) less than about 6. The blend has a glass transition temperature of about 0.degree. C. or less. The film may be a one-sided cling film having a polyolefin slip layer opposite the cling layer.
