  • Patent number: 10155364
    Abstract: Machine direction oriented coextruded multilayer film structures for use as labelstock and die cut adhesive labels are described. The labelstocks comprise extruded machine direction oriented multilayer films and an adhesive layer. The multilayer film structures include skin layers made from a mixture of 70% to about 99.9% by weight of at least one propylene polymer, and from about 0.1% to about 20% by weight of at least one ethylene polymer, or from about 0.1% to about 25% by weight of at least one propylene polymer, and from about 75% to about 99.9% by weight of at least one ethylene polymer. The coextruded multilayer films are stretch oriented in the machine direction at a temperature at about or above the melting temperature of the polyethylenes and optionally include an adhesive layer and release liner.

  • Patent number: 10150891
    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.
