The multilayered, opaque, biaxially oriented polyolefin film useful for printing sheets and as all-round label for labelling containers, comprises a vacuole-containing base layer (B), intermediate layers applied on both sides of the base layer, and outer layers applied on both sides of the intermediate layers. The intermediate layers have a thickness of 5-10 mu m and consist of 70 wt.% of propylene homopolymer. The outer layers consist of additional anti-caking agents and less than 2 wt.5 of particle-forming filler.

The intermediate layers have a thickness of 5-10 mu m and consist of 70 wt.% of propylene homopolymer. The outer layers consist of additional anti-caking agents and less than 2 wt.% of particle-forming filler. The thickness of each outer layer is 3-5 mu m. The intermediate layers have a thickness of >= 0.9 g/cm 3>. Each layer has a surface roughness (Rz) of 2.5 mu m. Independent claims are included for: (1) sheet out of foil; (2) method for printing of sheets; and (3) method for labelling containers. |
