Abstract
(EN) 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.
(FR) La présente invention concerne un film de polyoléfine multicouche comportant une couche centrale de polypropylène et une couche externe de polyoléfine recouvrant la couche centrale, cette couche externe contenant du polysiloxane particulaire, partiellement réticulé, en quantité suffisante pour réduire le coefficient de friction. Lorsque les particules du polysiloxane sont soumises à une contrainte mécanique, le polysiloxane non réticulé du polysiloxane particulaire est libéré, ce qui provoque un accroissement des caractéristiques de glissement des films lorsque ceux-ci sont placés dans des conditions de contrainte mécanique croissante.
