<p>Use of a laminating compound (1) with an stretchable plastic film (8, 8') at a first surface and a non-woven material (2) at the opposite surface, where the non-woven material is at least cold stretched in sections under partial destruction of the material structure, for producing a plastic molding (14), is claimed, where: the laminating compound is introduced in an injection molding tool; the non-woven material back-injected with a polymer melt is disposed at the surface; and the laminating compound is extended by an in-mold injection. Use of a laminating compound (1) with an stretchable plastic film (8, 8') at a first surface and a non-woven material (2) at the opposite surface, where the non-woven material is at least cold stretched in sections under partial destruction of the material structure, for producing a plastic molding (14), is claimed, where: the laminating compound is introduced in an injection molding tool; the non-woven material back-injected with a polymer melt is disposed at the surface; the laminating compound is extended by an in-mold injection; the plastic film is pressed at an assigned surface of the injection molding tool; and the non-woven material is pervaded at least partially from the polymer melt. An independent claim is included for a process for preparing the laminating compound suitable for the application, comprises providing the non-woven material, which is removed preferably from a roll, cold stretching the non-woven material at least in sections under partial destruction of the material structure, subsequently contacting the cold stretched non-woven material with a melt film (5) emerging from an extrusion die (4) for the formation of the stretchable plastic film, and conducting the melt film and the non-woven material for the lamination to such an extent by a slit between a cooling roller (6) and a smoothing band (7), where the non-woven material is fitted in the cooling roller and the melt film is fitted in the smoothing band.</p> |
