Title (EN) MULTILAYER POLYETHYLENE LAMINATES AND FILMS FOR USE IN FLEXIBLE PACKAGING MATERIALS
(FR) STRATIFIÉS DE POLYÉTHYLÈNE MULTICOUCHES ET FILMS DESTINÉS À ÊTRE UTILISÉS DANS DES MATÉRIAUX D'EMBALLAGE SOUPLES
Abstract:
(EN) Embodiments of multilayer films and laminate structures for flexible packaging comprise a multilayer polyolefin film comprising at least 3 layers. The multilayer polyolefin film comprises a first surface layer comprising: 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). The first surface layer also comprises a second composition comprising an ethylene based polymer having a density from 0.890 to 0.925 g/cc and a melt index (I2) from 0.2 to 2.0 g/10 min. The multilayer polyolefin film also comprises a first intermediate layer comprising the first composition.
(FR) Des modes de réalisation de films multicouches et de structures stratifiées d'emballage souple comprennent un film de polyoléfine multicouche comprenant au moins 3 couches. Le film de polyoléfine multicouche comprend une première couche de surface comprenant : une première composition comprenant 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). La première couche de surface comprend également une seconde composition comprenant un polymère à base d'éthylène ayant une densité située dans la plage allant de 0,890 à 0,925 g/cc et un indice de fluidité (I2) situé dans la plage allant de 0,2 à 2,0 g/10 min. Le film de polyoléfine multicouche comprend également une première couche intermédiaire comprenant la première composition.
