Abstract

The invention relates to an oriented multilayer polyolefin film which comprises a polyolefinic base layer and at least one non-heat-sealable top layer. The non-heat-sealable top layer contains at least one amorphous polymer which is in the top layer in the form of separated particles.

The invention also relates to a process for the production of the multilayer polyolefin film and to the use of the film.
