Abstract

L'invention se rapporte à des articles et à des film obtenus à partir de polymères à base d'éthylène fabriqués au moyen d'un système catalyseur d'alliage organométallique. L'orientation biaxiale améliore spectaculairement la transparence, la rigidité, la résistance au choc au mouton, la résistance au percement, et le rétrécissement. La résistance à la traction et la tension de rupture sont également améliorées. La rigidité du film, telle que mesurée par le module sécant, est augmentée de 300 % sur un film non orienté du même polymère d'éthylène. Ces articles et ces films sont utilisés comme emballages moulants, surenveloppes et dans des applications d'emballage à sec tels que des sandwichs et des céréales ainsi que dans des applications sans emballage telles que des albums photos ou porte-documents.
