Abstract

L'invention décrit une composition de polymères thermoplastiques de l'éthylène que l'on peut facilement extruder pour obtenir des pellicules. La composition présente un indice d'écoulement à l'état fondu inferieur à 0,7; elle comprend moins d'environ 15 % d'un polymère de l'éthylène à grande densité, au moins 85 % environ d'un polymère de l'éthylène à basse densité et au moins 0,005 % en poids d'un polyéthylène-glycol. La pellicule obtenue peut notamment servir à former des sacs d'emballage.
