摘要

The invention relates to a device for producing a multilayer three-dimensional structural film (70) and to a method for producing such a structural film (70), which has an irregularly undulating surface (OS). Furthermore, the invention relates to such a structural film (70) and to a bar-shaped article (71) made of such a structural film (70). In order to produce the structural film (70) a backing film (TF) and a cover film (DF) are joined together, wherein plant particles and/or plant chippings (PA) are applied beforehand to the top side (OTF) of the backing film (TF).
