Abstract
(EN)
Cast films formed from polyethylene are provided that can have desirable properties. In one aspect, a cast film comprises a layer formed from a composition comprising a first composition, wherein the first composition comprises at least one ethylene-based polymer and wherein the first composition comprises a MWCDI value greater than 0.9, and a melt index ratio (I10/I2) that meets the following equation: I10/I2 ≥ 7.0 - 1.2 x log (I2).
(FR)
L'invention concerne des films coulés formés à partir de polyéthylène qui peuvent présenter des propriétés souhaitables. Selon un aspect, un film coulé comprend une couche formée à partir d'une composition comprenant une première composition, la première composition comprenant au moins un polymère à base d'éthylène et la première composition comprenant une valeur MWCDI supérieure à 0,9, et un rapport d'indice de fluidité (I10/I2) qui satisfait l'équation suivante : I10/I2 ≥ 7,0 - 1,2 x log (I2).
