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.

Extrusion-coated strip for rigid packagings

A method for producing a strip consisting of aluminum or an aluminum alloy for packaging purposes, in particular for cans, can lids or can closures, which provides an individualized aluminum strip for packaging purposes, with which decorative or identification elements can be reliably embossed without additional production steps being required, for example at the producer of the packaging means, is achieved in that decorative or other identification elements are embossed into the strip in the last rolling pass of cold rolling and in that the strip thickness is greater in the area of the decorative and identification elements than in the remaining areas of the strip.
