  • Publication number: 20090280341
    Abstract: It is an object of the present invention to provide a shrink label comprising a multilayer film, which is superior in low temperature resistance, heat resistance, oil resistance, tearing properties along the perforation and appearance and does not peel in covering a container, as a base film, and a heat-shrinkable multilayer resin film which can effectively prevent the deterioration of the content of a container due to ultraviolet light and is superior in the tearing properties along the perforation and the oil resistance when the heat-shrinkable multilayer resin film is used as a shrink label for a container, and a shrink label comprising the heat-shrinkable multilayer resin film as a base film.

  • Publication number: 20090202851
    Abstract: It is an object of the present invention to provide a heat-shrinkable multilayer film which, in the case of using the heat-shrinkable multilayer film as a heat-shrinkable label for a container, does not produce delamination in covering a container, is superior in heat resistance, oil resistance, tearing properties along the perforation and appearance and can prevent the reduction in strength between the layers after a printing step, and a heat-shrinkable label comprising the heat-shrinkable multilayer film as a base film. The present invention is a heat-shrinkable multilayer film which comprises: an outer surface layer comprising a polyester type resin; and an intermediate layer comprising a polystyrene type resin, said outer surface layer and said intermediate layer being laminated by interposing an adhesive layer comprising a polyester type elastomer or a modified polyester type elastomer.

  • Publication number: 20070178264
    Abstract: The present invention provides a method for producing a high-quality nonconductive or semi-conductive seamless (jointless) tubular polyimide film in a simple, efficient, and economical manner, and the like. More specifically, the invention relates to an electrically non-conductive or electrically semi-conductive seamless tubular polyimide film comprising polyimide having at least two aromatic tetracarboxylic acid derivatives comprising 15 to 55 mol % of asymmetric aromatic tetracarboxylic acid component and 85 to 45 mol % of symmetric aromatic tetracarboxylic acid component and at least one aromatic diamine component, in which, as required, a specific amount of carbon black is dispersed, and relates to a method for producing the same.

  • Publication number: 20060159878
    Abstract: A multi-layered heat-shrinkable film composed of at least three layers has: front-back film layers each composed of a resin composition having cyclic olefin-based resin of from 55 to 95 mass % and linear low-density polyethylene of from 45 to 5 mass %; and an intermediate film layer composed of a resin composition having propylene-?-olefin random copolymer of from 95 to 55 mass % and cyclic olefin-based resin of from 5 to 45 mass %, or composed of a resin composition having: a resin composition of from 95 to 55 mass % mainly composed of the propylene-?-olefin random copolymer; and the cyclic olefin-based resin of from 5 to 45 mass % When immersed in a hot water of 90° C. for 10 seconds, the multi-layered heat-shrinkable film has a heat shrinkage in a lateral direction of 50% or higher, and has a tear propagation strength in a longitudinal direction of from 800 mN to 350 mN.
