Abstract: A strip-shaped pre-product for manufacturing can lids or can tabs of a can, preferably a beverage can having an aluminium alloy strip with at a least partial surface coating. The surface coating is provided on the side of the aluminium alloy strip used for the outer side of the can. A coated aluminium alloy strip is provided for manufacturing a can lid or a can tab, preferably a beverage can manufactured from a strip-shaped pre-product. A second coating is arranged on the first coating of the pre-product. The object of specifying a simple possibility of providing aluminium alloy strips with less sensitive lacquer layers, preferably coloured lacquer layers for the manufacture of can lids or can tabs, in particular beverage can lids and beverage can tabs, is achieved by means of a strip-shaped pre-product and with an aluminium alloy strip as well as by a method for its manufacture.

Abstract: An aluminium alloy strip for manufacturing a beverage can lid. The aluminium alloy strip has an aluminium alloy of the type AA5xxx. The object of specifying an aluminium alloy strip made of an aluminium alloy of the type AA5xxx for manufacturing a beverage can lid, which enables secure and cost-effective fastening of plastic elements on the manufactured beverage can lids, is achieved by the aluminium alloy strip having a heat-sealable coating, which contains polyolefin, on one side or on both sides.

Abstract: The invention relates to a method for producing a coated aluminum strip, in which the aluminum strip is unwound from a coil and fed into a unilateral or bilateral extrusion coating arrangement, the aluminum strip is extrusion coated with a thermoplastic polymer and after being extrusion coated, the aluminum strip is reheated to a metal temperature above the melting point of the thermoplastic polymer. The object of providing a method for producing an aluminum strip by which an extrusion-coated aluminum strip can be produced which can be processed at high processing speeds in follow-on composite tools is achieved in that the unilateral or bilateral plastics material coating of the aluminum strip is textured, after being reheated, using rolls which have a superficial structure.
