Disclosed is a film or sheet material comprising a blend of (1) a crystalline propylene polymer composition which is comprised of, by weight, (A) from about 30 to 65% of a copolymer of propylene with a C₄₋₈ alpha-olefin containing from 80 to 98% propylene, and (B) 35-70% of a co- or terpolymer of propylene with ethylene and, optionally, a C₄₋₈ alpha-olefin having an ethylene content of 5 to 10% when ethylene is the sole comonomer and an ethylene content of 0.5 to 5% and a C₄₋₈ alpha-olefin content of 1 to 9.5% when both ethylene and a C₄₋₈ alpha-olefin are used as comonomers, and (2) an olefin polymer. |
