The subject invention provides a film having at least one layer comprising an interpolymer of ethylene and at least one comonomer selected from the group consisting of C3-C20 .alpha.-olefins, dienes, and cycloalkenes, wherein the interpolymer is characterized as having a high degree of processability, good optical performance, and good mechanical properties. The subject invention further provides film fabrication processes and polymer compositions which are useful in preparing the subject films.
La présente invention concerne un film comportant au moins une couche comprenant un interpolymère de l'éthylène et au moins un comonomère appartenant au groupe des C¿3?-C¿20? .alpha.-oléfines, diènes et cycloalcènes. En l'occurrence, la caractéristique de l'interpolymère est qu'il se prête très bien au traitement, qu'il a un bon rendement optique et qu'il présente de bonnes propriétés mécaniques. L'invention concerne également des procédés de fabrication du film et des compositions de polymères convenant particulièrement à la préparation des films de l'invention.
