Abstract

See full text

A method for producing a primary laminate including a tabstock the steps of; 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 or 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, the top face of which is partly comprised of the top face of the tabstock and partly comprised of the top polyester layer of the heat sealable laminate, prior to reaching the laminating station; simultaneously feeding a plastic film stock which has top and bottom surfaces to the laminating station; and continuously extruding a polymeric adhesive between the top face of the primary substrate and bottom surface of the plastic film stock such that the two are adhered together with a bond strength greater than 15 N/cm as measured when the tabstock is pulled at 90.degree. to the machine direction and at 180.degree. to the primary substrate to form a primary laminate including a tabstock. The primary laminate formed can then be laminated to a board or synthetic secondary liner.
