Abstract

L'invention concerne une composition se prêtant à la formation d'un film ayant un module de flexion sécant à 1 % (MD ou TD) d'au moins 55 000 psi et une résistance au choc au mouton d'au moins 500 g. La composition comprend un polypropylène à large distribution de poids moléculaires contenant au moins 50 % en mol de propylène et ayant : une distribution des poids moléculaires (Mw/Mn) supérieure à 6, un indice de ramification (g'vis) d'au moins 0,95, et une résistance à l'état fondu d'au moins 2 cN; et un polyéthylène contenant au moins 70 % en mol d'éthylène et ayant : une densité de 0,910 à 0,923 g/cm3, un indice de fusion (b) de 0,1 à 1,2 g/10 min, un rapport d'indices de fusion (I21/I2) de 20 à 35, un poids moléculaire moyen en poids (Mw) de 150 000 à 400 000 g/mol, et une distribution de comonomères perpendiculaire et/ou au moins un premier pic et au moins un second pic dans une analyse de distribution des comonomères.
