发明名称 Compositions having particular utility as stretch wrap cling film
摘要 A novel composition is disclosed comprising about 85 to about 99 weight percent based on the composition of a polymeric ethylenic containing component having a density no greater than 0.94 g/cc, and about 1 to about 15 weight percent based on the composition, of a propylene polymer comprising 0 to less than about 1 weight percent based on the polymer, of olefin comonomer units and from about greater than 99 to 100 weight percent propylene, based on the polymer, the propylene polymer having a viscosity of about 1 to about 2,000 mPa.s at 190° C. and a needle penetration of about 5 to about 50 dmm at 23° C. Also disclosed are films produced from the composition, both blown and cast, and both monolayer and multilayer. Also disclosed are processes for stretch wrapping and forming blown film.
