A method for producing a primary laminate (1b) comprising a tab material, the metal foil layer provided with a food contact layer of the bottom portion (4) with the polyester top layer (5) and a seal laminate comprising a an (1) a feed Kyusuru stage laminating station, the bottom side or the metal foil layer of the polyester layer (5) (4) where in which printing is performed, feeding the seal laminate (1) in the stacking station stages and; seal laminate and at the same time send Kyusuru stage a narrow width of the tab material (6) than (1) to the lamination station, before reaching the laminating station, the bottom and the seal laminate of the tab material in contact with the polyester top layer to form a primary substrate (1a), the top surface of the primary substrate is a heat-sealable laminate while being partially formed from a top surface of the tab material (6) as partially formed from a polyester top layer (5), simultaneously feeding Kyusuru step narrower than the seal laminate (1) of the tab material (6) to the laminating station and; plastic with top and bottom surfaces and film material (8) simultaneously feeding Kyusuru stage laminating station and a bond strength that is measured when the tab material is pulled at 180 ° for 90 ° and the primary substrate to the machine direction between the top surface and the bottom surface of the plastic film material of the primary substrate top surface and plastic film material (8) primary base material as the bottom is adhered to each other by a large bond strength than 15N / cm of (1a) method of producing comprising the, primary laminate including a tab element the (1 b); polymeric adhesive (7) on extruded continuously, forming a primary laminate including a tab material.
