ABSTRACT:
The present invention relates to a monolayer film formed from a composition comprising from about 90 weight percent to about 99 weight percent based on the total weight of the composition of a component selected from a homopolymer of ethylene; an ethylene alpha olefin copolymer; an ethylene vinyl acetate copolymer; and mixtures thereof; wherein the component has a density no greater than 0.94 g/cc; and from about 1 weight percent to about 10 weight percent based on the total weight of the composition of a copolymer of propylene with a monomer copolymerizable therewith, having a viscosity of between about 1 and about 2000 cP at 190 degrees C., and a needle penetration of about 50 dmm to about 150 dmm at 23 degrees C., wherein the monomer comprises from about 10 weight percent to about 40 weight percent of the total weight of the propylene copolymer. The monolayer films of the present invention are particularly well suited for use as a stretch film.
