Abstract

La présente divulgation concerne des polymères de polyéthylène et des films fabriqués à partir de ceux-ci. Dans certains modes de réalisation, un copolymère de polyéthylène comprend 90 % en poids ou plus d'unités éthylène et un reste d'unités comonomères C3-C20. Le copolymère de polyéthylène a une distribution de composition bimodale, une densité allant de 0,914 g/cm3 à 0,925 g/cm3, un indice de fusion de 0,1 g/10 min à 1 g/10 min, un indice de fusion sous charge élevée (HLMI) de 21 g/10 min à 70 g/10 min, un rapport d'indice de fusion (MIR) de 40 à 65, et une distribution de poids moléculaire (MWD) de 4 à 7.
