Title (EN) THERMOFORMED FILM COMPOSITIONS WITH ENHANCED TOUGHNESS AFTER THERMOFORMING PROCESSES
(FR) COMPOSITIONS DE FILM THERMOFORMÉ PRÉSENTANT UNE TÉNACITÉ AMÉLIORÉE APRÈS DES PROCÉDÉS DE THERMOFORMAGE
Abstract:
(EN) Embodiments of thermoformed monolayer or multilayer films are provided, wherein the thermoformed monolayer multilayer films comprise a first composition comprising at least one ethylene-based polymer, wherein the first composition comprises a Molecular Weighted Comonomer Distribution Index (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 modes de réalisation de films monocouche ou multicouche thermoformés, les films monocouche ou multicouche thermoformés comprenant une première composition comportant au moins un polymère à base d'éthylène, la première composition comprenant une valeur d'indice de distribution de comonomère pondéré moléculaire (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).
