Multilayer polyolefin film having a core layer of a propylene polymer and an outer polyolefin layer on the core layer, the outer polyolefin layer including a coefficient of friction reducing amount of a particulate, partially cross-linked, polysiloxane. Non-cross-linked polysiloxane in the particulate polysiloxane is released when the particles are subjected to mechanical stress which causes the slip of the films to increase as they are placed under increasing mechanical stress.
