    摘要： This invention relates to a multilayered film for use as in-mold label, comprising: a core layer having a first surface and a second surface, the core layer being comprised of a polymeric material and particulate solids dispersed in the polymeric material; and a first skin layer overlying the first surface of the core layer; the film being formed by co-extruding the core layer and first skin layer to form the multilayered film, hot-stretching the film at a temperature above the expected service temperature of the label to provide the film with a machine direction orientation, the density of the film being reduced by about 5% to about 25% during hot-stretching, and annealing the film at a temperature above the expected service temperature of the label; the film having a machine direction Gurley stiffness value in the range of about 30 to about 120, a machine direction shrinkage of less than about 2%, and a machine direction shrink tension at 200° F. (93.3° C.) of less than about 100 psi.

    摘要： This invention relates to an imaged receptor laminate, comprising: a thermoplastic core layer having a first side and a second side; a thermoplastic skin layer overlying said first side of said core layer, said skin layer comprising a major amount of a thermoplastic copolymer or terpolymer derived from ethylene or propylene and a functional monomer selected from the group consisting of alkyl acrylate, acrylic acid, alkyl acrylic acid, vinyl acetate and combinations of two or more thereof, said skin layer having a melting point in the range of about 50.degree. C. to about 120.degree. C., said core layer having a melting point that is higher than the melting point of said skin layer; and an electrostatically formed and developed image adhered to said skin layer. In one embodiment, a dielectric layer overlies the toned image and the skin layer. In one embodiment, a conductive carrier sheet overlies the foregoing dielectric layer. In one embodiment, an overlaminate protective film layer overlies the image and the skin layer. In one embodiment, an overlaminate protective film layer overlies the dielectric layer. This invention also relates to a process for making the foregoing imaged receptor laminate.

    摘要： Olefin polymer films composed essentially of a copolymer of a major proportion of ethylene with a minor proportion of a higher .alpha.-olefin monomer and an effective amount of a tackifying agent are provided which have unusually high Elmendorf tear strength in the machine direction, a good balance of machine direction to transverse direction Elmendorf tear strengths, and excellent cling properties. Such films are exceptionally well suited for use as a stretch/cling film in various packaging and palletizing applications.
