    摘要: This invention relates to a film comprising a machine direction oriented polymeric film prepared from (A) at least one propylene homopolymer or copolymer or lend of two or more thereof, wherein (A) has a melt flow rate from about 6 to about 30 and (B) an olefin elastomer having a melt flow rate of 0.5 to 10. In one embodiment, the film also contains a nucleating agent. In one embodiment, these films are clear. The films have good stiffness and clarity with low haze. These films are useful in preparing labels and may be used as a monolayer film or in a multilayer film. In one embodiment, the films are printable. Die-cut labels are also described which comprise a composite comprising the extruded, machine-direction oriented polypropylene copolymer films of the present invention in combination with an adhesive associated with said copolymer films for adhering said label to a substrate. Multilayer composites also are described which comprise a label facestock material comprising an extruded oriented multilayer film of the present invention, an adhesive layer associated with said facestock material, and a release-coated liner or carrier. Combinations of the labels of the present invention joined with layer of adhesive to a substrate such as glass bottles also are described.
