Abstract

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.
