Title (EN) FILMS MADE FROM POLYETHYLENE COMPOSITIONS AND PROCESSES FOR MAKING THE SAME
(FR) FILMS FABRIQUÉS À PARTIR DE COMPOSITIONS DE POLYÉTHYLÈNE ET PROCÉDÉS POUR LES FABRIQUER
Abstract:
(EN) The present disclosure provides films made of polyethylene (PE) compositions. In at least one embodiment, a film includes a polyethylene composition, comprising: ethylene content and from 0 to 25 mol% of C3-C40 olefin comonomer content, based upon the total weight of the polyethylene composition, the polyethylene composition having a total internal plus terminal unsaturation greater than 0.7 unsaturations per 1000 carbon atoms, the film having: an Elmendorf Tear value in the machine direction of from 10 g/mil to 300 g/mil, and a Dart Drop Impact of from 100 g/mil to 800 g/mil. In at least one embodiment, the present disclosure provides for processes to make a film.
(FR) La présente invention concerne des films constitués de compositions de polyéthylène (PE). Dans au moins un mode de réalisation, un film comprend une composition de polyéthylène, comprenant : de l'éthylène et de 0 à 25 % en moles de comonomère d'oléfine en C3-C40, rapporté au poids total de la composition de polyéthylène, la composition de polyéthylène ayant une insaturation totale interne plus terminale supérieure à 0,7 insaturation pour 1000 atomes de carbone, le film ayant une valeur de déchirure Elmendorf dans la direction de la machine allant de 10 g/mil à 300 g/mil et une résistance au choc de masse tombante de 100 g/mil à 800 g/mil. Dans au moins un mode de réalisation, la présente invention concerne des procédés de fabrication d'un film.
