EXTRUSION-COATED STRAP FOR RIGID PACKAGINGS

摘要

The invention relates to a method for producing a coated aluminium strip, in which the aluminium strip is unwound from a coil and fed into a unilateral or bilateral extrusion coating arrangement, the aluminium strip is extrusion coated with a thermoplastic polymer and after being extrusion coated, the aluminium strip is reheated to a metal temperature above the melting point of the thermoplastic polymer. The object of providing a method for producing an aluminium strip by which an extrusion-coated aluminium 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 aluminium strip is textured, after being reheated, using rolls which have a superficial structure.
