Oriented polyolefin multilayer film having a base layer containing polypropylene and at least one outer layer, the outer layer including a mixture of a first antiblock additive having a mean particle size of from 3 to 6 mu m and a second antiblock additive having a mean particle size of from 2 to 4 mu m, with the proviso that when the first additive is present in an amount of from 3 to 5 mu m, the second antiblock additive has a particle size of greater than 2.5 mu m. Such films have particularly good antiblock characteristics compared with those having either of the particular types of antiblock agent on their own. |
