Abstract: A primary laminate including a tabstock in which a seal laminate including a foil layer and a top foam layer, a tabstock and a plastic film stock are fed to a laminating station is provided herein. At the lamination station, a curtain of polymeric adhesive is extruded between the plastics film stock and the top face of the primary substrate, which is partly comprised of the top face of the tabstock and partly comprised of the top foam layer of the seal laminate. Use of primary laminates obtained by such a process to form seals for sealing a container, for food or drink stored at low temperatures, is also described.

Abstract: A method for producing a primary laminate including a tabstock by feeding a seal laminate comprising bottom food contact layers including a foil layer and a top polyester layer to a laminating station wherein either the foil layer of the underside of the polyester layer has been printed; simultaneously feeding a tabstock, which is narrower than the seal laminate, to the laminating station such that the bottom of the tabstock and the top polyester layer of the seal laminate come into contact to form a primary substrate, simultaneously feeding a plastic film stock; and continuously extruding a polymeric adhesive between the top face of the primary substrate and bottom surface of the plastic film stock.

Abstract: A method of making and a primary laminate produced from the method including a tab used in container closure systems is provided. The laminate may be slit and punched to produce container closure liners that can be sealed to the mouth of containers. In one approach, the laminate has a colored top surface. The colored top surface of the container closure liner may be visible once the liner has been sealed to the mouth of the container.

Abstract: A seal for a container for comestibles, especially potable liquids, and in particular for use for sealing polyester containers such as bottles, which is suitable for passage through a PET recycling process, comprises a metal foil layer, a foam layer and a plastics film layer as well as a heat sealable layer below the foil. The foam is selected for its density and thickness so is to confer upon the seal a high buoyancy. The adhesion a between the foam and the foil is increased compared to currently available products, in order to prevent de-lamination between the foil and the foam during the recycling process.

Abstract: A covering substrate which is inexpensive to manufacture and adhere to a container yet provides a hygienic environment at a top portion of the container as well as provides multiple promotional or advertising surfaces. A covering substrate capable of being bonded to a rim of a container, the container including a top wall and the rim extending beyond the top wall defining a top portion of the container, the covering providing a hygienic environment at the top portion of the container, including a substrate, a heat seal coating laminated to the substrate and disposed for bonding the substrate to the container substantially along the perimeter of the rim, and a bondable material layered in part to the substrate opposite the heat seal coating, a portion of the bondable material defining a tab therein substantially contained within the perimeter of the substrate.
