Label film for all-round labels

摘要

The invention relates to a multi-layer, opaque, biaxially-oriented polyolefin film with a thickness of at least 40 μm including 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.

1. A multi-layer, opaque, biaxially-oriented polyolefin film with a thickness of at least 40 μm comprising:
a vacuole-containing base layer B and intermediate layers applied on both sides thereof and covering layers on both sides thereof, wherein both intermediate layers have a thickness of at least 3 μm up to 10 μm and contain at least 70% by weight of a propylene homopolymer, and both covering layers are constructed of a mixture of incompatible polymers, both covering layers have a thickness of at least 2 to 10 μm, both covering layers have a surface roughness Rz of at least 2.5 μm up to 8 μm and both covering layers contain less than 2% by weight of particle-shaped fillers.
