摘要

Machine-direction oriented polypropylene homopolymer and propylene copolymer films are described wherein the propylene copolymer is one selected from the group consisting of propylene-ethylene copolymers containing up to about 10 percent by weight of ethylene and propylene-1-butene copolymers containing up to about 15 percent by weight of 1-butene wherein the oriented films have an opacity of less than about 10 percent and a haze of about 10 percent or less in the machine-direction and in the cross-direction.
