Both intermediate layers have a thickness of at least 3µm and contain at least 70 wt.-% of a propylene homopolymer. Both cover layers are composed of incompatible polymers. The inner cover layer has a surface roughness Rz of at least 3.0μm and the outer cover layer has a roughness of 1 to 3μm, wherein the roughness of the inner cover layer is at least 1.5 units greater than the roughness of the outer cover layer.
