Producing a molded body with a three-dimensionally structured surface, comprises: mixing a starting material, which contains non-crosslinked polyolefins and non-crosslinked ionomers and optionally other additives as essential components, and applying as a flat film or a flat film body; and subsequently deep drawing the film into a component mold, which contains the desired grain pattern as a negative for producing the three-dimensionally structured surface and for forming the molded body in a grain-imparting negative thermoforming method.
