Abstract
The invention relates to a multilayered, opaque, biaxially oriented polyolefin film having a thickness of at least 30 μm consisting of a vacuole-containing base layer and intermediate layers applied to both sides thereof, and cover layers applied to either side of the intermediate layers. Both intermediate layers have a thickness of at least 3 μm and contain at least 70% by weight of a propylene homopolymer. Both cover layers are constructed from incompatible polymers. The inner cover layer has a surface roughness Rz of at least 3.0 μm and the outer cover layer has a roughness from 1 to 3 μm, the roughness of the inner cover layer being at least 1.5 units greater than the roughness of the outer cover layer.
