BIAXIALLY ORIENTED PROPYLENE POLYMER FILMS

摘要

A multilayer biaxially oriented propylene polymer film, characterized in that the support layer of said multilayer film comprises: (A) 15 to 75 wt % of a propylene homopolymer and (B) 25 to 85 wt % of a propylene copolymer composition comprising (percent of (a) and (b) based on the component (B)): (a) 50 to 85 wt % of a propylene copolymer containing from 0.05 to 1.5 wt % of alpha-olefin units having from 2 to 10 carbon atoms other than propylene; and (b) 15 to 50 wt % of a propylene copolymer containing less than 20 wt % of alpha-olefin units having from 2 to 10 carbon atoms other than propylene
