Abstract of the Disclosure An oriented, multilayer polyolefin film is described. It includes a base layer essentially containing poly- propylene, and at least one heat-sealable outer layer. The heat-sealable outer layer contains from 0.1 to 0.5% by weight of SiO2 which has been subjected to organic aftertreatment coating and has a mean particle diameter of from 2 to 6 µm, preferably from 4 to 5 µm. The ratio between the mean particle diameter and the outer layer thickness is in the range from 3 to 11. Also described is a process for the production of the multilayer polyolefin film and the use thereof.
