  • Patent number: 6376058
    Abstract: A polypropylene based composition is described which comprises a mixture of (A) a propylene polymer or copolymer and (B) an alkylene-alkyl acrylate copolymer. These polypropylene based compositions are useful in the preparation of continuous films such as by extrusion, and the films can be oriented by stretching in the machine direction. The films prepared from the polypropylene compositions of this invention exhibit a variety of useful properties including the desired printability, stiffness, and die-cuttability to be useful as a facestock in preparing labels. Films prepared from the polypropylene based compositions of the invention also can be used as a base film, and the films can be overlaminated with a functional film. Machine-direction oriented monolayer and multilayer film facestocks for labels, and adhesive containing film labelstock for use in adhesive labels also are described.
