<p>The invention relates to a multi-layered, opaque, biaxially-oriented polyolefin film with a thickness of less than 150 µm and which comprises f. a base layer that contains vacuoles and at least one polymer of at least one olefin, g. an inner intermediate layer that contains at least one polymer of at least one olefin, h. an outer intermediate layer that contains at least one polymer of at least one olefin, i. an inner cover layer which is in contact with the inner intermediate layer and contains 5-70 wt.% of at least one polyethylene and 30 - 95 wt.% of at least one propylene polymer, and j. an outer cover layer which is in contact with the outer intermediate layer and contains 5-70 wt.% of at least one polyethylene and 30-95% of at least one propylene polymer, each amount indication relating to the weight of the layer in question, and characterised in that said outer intermediate layer has a thickness of 0.5 to 5 µm and contains 4.5 to 30 wt.% of pigments, preferably ???2, in that the outer cover layer has a thickness of > 0 to < 2 µm, and in that the film has a gloss on either side of less than 50 gloss units measured according to DIN EN ISO 2813 at an angle of 60° and at a temperature of 25°C.</p> |
