Abstract
The invention relates to transparent multilayer biaxially oriented polyolefin films comprising a base layer and at least one outer matt covering layer, which contains at least two incompatible polymers and has a surface roughness of at least 2.0 [mu]m. The covering layer contains a polydialkyl siloxane having a viscosity of 100,000 to 500,000 mm2/s. The surface of said covering layer is pre-treated by means of corona.
