  • Patent number: 8691394
    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: 20140053509
    Abstract: The present subject matter provides a shrink film free of silicon-containing material, fluorine-containing material, and solvent-formed seams. The shrink film utilizes a water soluble layer covering an adhesive layer. The water soluble layer is in dry form and non-tacky, allowing processing of the shrink film subsequent to adhesive application to the shrink film. When the water soluble layer is dissolved, the adhesive layer is exposed and is capable of forming a permanent bond. The adhesive can be used to form a seam in the film and/or can be used to form a bond between the film and a substrate. The water soluble layer facilitates removal of an optional release liner from the adhesive. A substrate with the shrink film attached thereto and a related method of attaching a heat shrinkable film to a substrate are also disclosed.

  • Publication number: 20140044902
    Abstract: The present invention for the first time proposes a multilayer sheet- or tube-type food casing or food film produced by the nozzle blast-drawing process and biaxially oriented by the triple-bubble process, which is fashioned as a food packaging having the form of shrink bags, sealable films, wrapping films or the like. This novel food casing or food film comprises at least nine layers of which an EVOH layer has the form of an oxygen barrier symmetrically embedded between two PA layers intended to impart strength and in turn symmetrically enclosed by two PO layers for the water vapor barrier, and wherein the external layer is formed by a highly temperature-resistant material such as PET which on top of its excellent optical properties also enables clearly higher speeds for further processing (cycle numbers) than were previously known.

    Abstract: A label having an adhesive applied proximal to an inner surface of a shrink film (such as a shrink sleeve), which is not transferred to labeling apparatus during application of the shrink label to an article. Thus, the shrink sleeve does not result in a build-up of adhesive on label application apparatus, thereby preventing apparatus downtime; and cannot be removed from the article to which it is applied, (or cannot be removed without damage being done to the label), thereby preventing removal and re-use of the shrink sleeve on counterfeit goods.
