Abstract
The invention relates to a multi-layer, opaque, biaxially-oriented polyolefin film with a thickness of at least 40 μm of a vacuole-containing base layer B and intermediate layers Z applied on both sides thereof of at least 70% by weight of a propylene homopolymer, and with a thickness of at least 3 μm and a covering layer D on both sides thereof of a mixture of incompatible polymers and respectively a surface roughness Rz of at least 2.5 μm (with a cut-off of 0.25 mm). The invention also relates to the use of this film as a wrap-around label.
