Non-sealable, transparent, oriented multilayer polypropylene film, process for making it, and its use.

摘要

The invention relates to a transparent, non-heat-sealable, oriented multilayer polyolefin film, which comprises a base layer containing polypropylene, and at least one non-heat-sealable top layer. The non-heat-sealable top layer contains from 0.1 to 0.6 % by weight of SiO2, based on the weight of the top layer, which has been organically aftertreated and has a mean particle diameter of from 2 to 6 mu m, preferably from 4 to 5 mu m. The invention also relates to a process for the production of the multilayer film and to the use of the film.
