Abstract:
(EN) Disclosed herein is a cast film comprising a polyethylene composition comprising the reaction product of ethylene and optionally one or more alpha-olefin comonomers, wherein said polyethylene composition is characterized by the following properties: a melt index, I2, measured according to ASTM D1238 (2.16 kg, 190°C), of from 1 to 20 g/10 min; a density (measured according to ASTM D792) of from 0.935 to 0.970 g/cm3; a melt flow ratio, I10/I2, wherein I10 is measured according to ASTM D1238 (10 kg, 190°C) of from 5.5 to 7.0; a molecular weight distribution (Mw/Mn) of from 2.2 to 3.5; and a vinyl unsaturation of greater than 0.12 vinyls per one thousand carbon atoms present in the backbone of the composition.
(FR) L'invention concerne un film coulé comprenant une composition de polyéthylène comprenant le produit de réaction d'éthylène et éventuellement d'un ou de plusieurs comonomères d'alpha-oléfine, ladite composition de polyéthylène étant caractérisée par les propriétés suivantes : un indice de fluidité, I2, mesuré selon la norme ASTM D1238 (2,16 kg, 190 °C), de 1 à 20 g/10 min ; une masse volumique (mesurée selon la norme ASTM D792) de 0,935 à 0,970 g/cm3 ; un rapport d'indices de fluidité, I10/I2, I10 étant mesuré selon la norme ASTM D1238 (10 kg, 190 °C) de 5,5 à 7,0 ; une distribution de poids moléculaire (Mw/Mn) de 2,2 à 3,5 ; et une insaturation vinylique supérieure à 0,12 vinyle pour mille atomes de carbone présents dans le squelette de la composition.
