Zusammenfassung:	The present invention is directed to a polymer composition comprising a bi- or multimodal ethylene polymer (P) and a nucleating agent being a dicarboxylic acid of 5 a cyclic alkane. Further, the present invention is directed to an article comprising said polymer composition and the use of a nucleating agent being a dicarboxylic acid of a cyclic alkane to decrease the water vapour transmission rate and oxygen transmission rate of a polyethylene film. La présente invention concerne une composition polymère comprenant un polymère d'éthylène bi-ou multimodal (P) et un agent de nucléation étant un acide dicarboxylique d'un alcane cyclique. En outre, la présente invention concerne un article comprenant ladite composition polymère et l'utilisation d'un agent de nucléation qui est un acide dicarboxylique d'un alcane cyclique pour diminuer le taux de transmission de vapeur d'eau et le taux de transmission d'oxygène d'un film de polyéthylène.
