摘要

The multi-layer plastic-molded part comprises a plastic layer with an inner-lying barrier layer, and a brake line intended in the barrier layer. The barrier layer in the area of the brake line has embrittlement, which is produced by irradiation of laser. The molded part has a package or a container with embrittled areas of the barrier layer. The molded part is produced in a sandwich-injection process, where the barrier layer forms a core component surrounded by a film component of another plastic. The plastic-molded part is plastic foil or a plastic plate or a plastic tube. The multi-layer plastic-molded part comprises a plastic layer with an inner-lying barrier layer, and a brake line intended in the barrier layer. The barrier layer in the area of the brake line has embrittlement, which is produced by irradiation of laser. The molded part has a package or a container with embrittled areas of the barrier layer. The molded part is produced in a sandwich-injection process, where the barrier layer forms a core component surrounded by a film component of another plastic or the molded part is produced in a multi-layer co-extrusion method, where barrier layer forms one of the inner layers and is covered by multi layers. The plastic-molded part is plastic foil or a plastic plate or a plastic tube. An independent claim is included for a method for the production of plastic-molded part.
