POLYETHYLENE STRETCH FILM

摘要

A film comprising greater than 70 wt %, based on the weight of the film, of a core layer comprising a core composition comprising: (a) within the range of from 50 to 99 wt% linear low density polyethylene based on the weight of the core composition; and (b) within the range of from 1 to 50 wt% propylene-alpha-olefin copolymer based on the weight of the core composition, wherein the propylene-alpha-olefin copolymer possesses: (i) a melting temperature (Tm) of less than 105°C, and (ii) a heat of fusion (Hf) of less than 75 J/g; wherein the film is a cast or blown film. The films have excellent strength and elasticity and are ideal for such applications as stretch wrap.
