摘要

Process for treating a carrier film made from a plastic or polymer comprises applying a functional layer as conducting path on the film so that material parts enter recesses of the functional layer to anchor the layer in the foil. Preferred Features: The shape and depth of the recesses are determined by radiating and etching conditions. The functional layer is passive or functional. Anchoring is carried out by allowing material parts of the functional layer to penetrate the recesses of the film. An adhesion promoter is provided between the layer and film to increase the adhesive strength. The functional layer is made from metal or non-metal and is conducting or non-conducting.
