A polymer composition comprising (i) at least 70 wt% of low-density polyethylene (LDPE) homopolymer or copolymer having a density of 905 to 935 kg/m3 (ISO 1183-2) and an MFR2 of 0.1 to 10 g/10min (ISO1133 at 190°C, 2.16 kg); (ii) 0.5 to 20 wt% of a high density polyethylene (HDPE) having a density of 940 kg/m3 or more and an MFR2 of 0.1 to 50 g/10min; and (iii) 0.05 to 10 wt% of an aliphatic, preferably alkyl, functional inorganic nanoparticle filler. L'invention concerne une composition polymère comprenant (i) au moins 70% en poids de polyéthylène basse densité (LDPE) homopolymère ou copolymère ayant une densité de 905 à 935 kg/m3 (ISO 1183-2) et un MFR2 de 0,1 à 10 g/10 min (ISO1133 à 190°C, 2,16 kg) ; (ii) 0,5 à 20% en poids d'un polyéthylène haute densité (PEHD) ayant une densité de 940 kg/m3 ou plus et un MFR2 de 0,1 à 50 g/10 min ; et (iii) 0,05 à 10% en poids d'une charge de nanoparticules inorganiques, de préférence alkyle, fonctionnelle.
