    Abstract: A coextruded, heat-sealable film structure includes a core layer of a thermoplastic polymer having a first side and a second side. A functional layer which is printable, sealable, or can be laminated or is treatable for printing, sealing, or laminating is on the first side of the core layer. A heat-sealable layer is on the second side of the core layer. The heat-sealable layer is composed of a thermoplastic polymer and an amount of a slip system, based upon the entire weight of the heat-sealable layer, sufficient to reduce the coefficient of friction and improve the slip performance of the film structure. The slip system is composed of a silicone gum and at least one antiblocking agent. The film structure exhibits the desirable combination of improved converting performance and excellent machinability performance.

  • Publication number: 20040166298
    Abstract: A plastic masking film comprises at least two layers, an outer layer having sufficient surface energy to ensure the adherence of paint, and an inner layer providing cling to a surface. The outer layer comprises a corona-treated thermoplastic material having a surface with a surface energy greater than 50 dynes/cm. at the time of manufacture and which remains at a minimum of 35 dynes/cm. until use. The thermoplastic material of the outer layer comprises one or a combination of members selected from the group consisting of ethylene vinyl acetate, polyvinyl alcohol, polyvinyl acetate, ethylene vinyl alcohol, and high density polyethylene. The inner layer comprises high density polyethylene. Desirably, the film also includes a central core layer formed of one or a combination of polyolefins, preferably low-density polyethylene or linear low-density polyethylene, compatible with the inner and outer layers.

  • Publication number: 20040166347
    Abstract: A covering material comprising a first layer, which forms the wearing layer of the structure and contains an ionomer, as well as a second layer next to the first layer. According to the invention, the first layer contains a wear-resistant and electrically conductive ionomer polyelectrolyte and the second layer is electrically conductive. The first layer comprises in particularan ionomer, which is a polymer of a co- or terpolymer of ethylene and acrylic or methacrylic acid, or any other known ionomer, and a block polyether, the polymer being ionically crosslinked with alkali and/or alkaline-earth and/or metal cations. The second layer forms the bottom layer of the structure, and it is made up of a polyolefin elastomer that has been rendered electrically conductive. The material according to the invention is suitable as covering for ESD applications.

  • Publication number: 20040166351
    Abstract: Polypropylene resin compositions are provided that are useful in the production of biaxially oriented polypropylene films (BOPPs). The resins of the present invention are blends of high crystalline (low solubles) polypropylene homopolymer and an ethylene/propylene random copolymer (RCP). These blends can be used to replace standard high solubles BOPP grade polypropylene homopolymers. In addition, the use of high crystalline polypropylene homopolymers in the blends imparts improved stiffness to the finished films while maintaining good processability of the blends.

  • Publication number: 20040161623
    Abstract: The present invention includes a laminate and formation of a laminate having at least one layer of an ionomer and at least one layer of an acid polymer or blend of acid polymer and a thermoplastic polyolefin that can be thermoformed to form a shaped laminate. The shaped laminate can then be contacted with a plastic substrate such as a thermoplastic polyolefin to form a composite article by such means as, for example, injection molding. The laminate can be pigmented to eliminate the need to paint the surface of the plastic substrate. Impact and scratch resistant articles can be formed from the laminated substrate such as automotive parts, appliance body parts and sporting equipment.
