  • Patent number: 9446554
    Abstract: The invention relates to the use of a multilayer, biaxially oriented polyolefin film comprising at least five layers as the label in deep drawing, which film is constructed from the following layers I the base layer is free from vacuoles, and IIa the outer intermediate layer is free from vacuoles and contains at least 95% by weight propylene polymer, which polymer has a propylene content of 98 to 100% by weight relative to the propylene polymer, and IIIa printing may be applied to the outer cover layer, and IIb the inner intermediate layer is constructed essentially from propylene polymer and contains vacuoles, and IIIb the inner cover layer is applied to the surface of the inner intermediate layer and is a sealable cover layer, and is a sealable cover layer, and has a sealing initiation temperature <130° C.

  • Publication number: 20120058304
    Abstract: The invention relates to a multilayered, opaque, biaxially oriented polyolefin film having a thickness of at least 30 ?m consisting of a vacuole-containing base layer and intermediate layers applied to both sides thereof, and cover layers applied to either side of the intermediate layers. Both intermediate layers have a thickness of at least 3 ?m and contain at least 70% by weight of a propylene homopolymer. Both cover layers are constructed from incompatible polymers. The inner cover layer has a surface roughness Rz of at least 3.0 ?m and the outer cover layer has a roughness from 1 to 3 ?m, the roughness of the inner cover layer being at least 1.5 units greater than the roughness of the outer cover layer.
