Punched component

Abstract

The invention relates to a punched component comprising: a) laminating a polymer film onto a metal sheet, b) subjecting the metal sheet to a punching process, by means of which the punched component is produced, wherein a polymer film is used which is provided with a cold-flowable pressure-sensitive adhesive.
