Moulded part and flexible film with a protected printed conductor, and method for producing the same

A plastic part having an embedded protected conductor track comprising:

• (a) a plastic film, as a backing layer, that has a metalizable primer layer applied thereto,
• (b) a structured, metallic, electrically conducting layer that includes at least one electrical conductor track, and that is applied to the primer layer, wherein the backing layer, primer layer, and conducting layer form a composite;
• and
• (c) a plastic article that is firmly connected to the composite in such a way that the plastic article covers at least part of the metallic, electrically conducting layer.

A process for making a flexible film that includes:

• (i) a plastic film, as a backing layer, that has a metalizable primer layer applied thereto,
• (ii) a structured, metallic, electrically conducting layer that includes at least one electrical conductor tracks and that is applied to the primer layer, and
• (iii) an outer film that (a) is firmly connected to the backing layer, the primer layer, and the metallic, electrically conducting layer, and (b) covers at least part of the metallic, electrically conducting layer,
• wherein the process comprises:
• (a) applying a primer to a plastic film and forming a structured primer layer;
• (b) drying the primer layer;
• (c) metalizing the structured primer layer and building up an electrically conducting layer, wherein the plastic film, primer layer, and electrically conducting layer form a composite;
• (d) connecting the composite to a plastic outer film by welding or adhesive bonding.

• (b) drying the primer layer;
• (c) metalizing the structured primer layer and building up an electrically conducting layer;
• (d) adhesively bonding a preformed thermosetting or thermoplastic plastic article on the side of the electrically conducting layer of the composite in such away that the plastic article covers at least part of the electrically conducting layer.
