Abstract

L'invention concerne un film polymère rétrécissable à orientation biaxiale, présentant une capacité de retrait dans la direction machine (DM) supérieure à la capacité de retrait dans la direction transversale (DT), de sorte que DT soit inférieur ou égal à DM/2 dans la plage de températures allant de 100 ~C à 140 ~C. Ce film comprend au moins un des constituants suivants: (a) un copolymère polyoléfinique; (b) un terpolymère polyoléfinique; (c) des mélanges de copolymères et d'homopolymères polyoléfiniques; (d) des mélanges de copolymères et de terpolymères polyoléfiniques; (e) des mélanges de terpolymères et d'homopolymères polyoléfiniques; et (f) des mélanges de copolymères, d'homopolymères et de terpolymères polyoléfiniques. Le copolymère en question comprend un premier et un second monomère. Le premier monomère est choisi dans le groupe constitué par l'éthylène, le propylène, le butylène et leurs mélanges. Le second monomère est choisi dans le groupe constitué par les monomères alpha-oléfiniques ayant de deux à dix atomes de carbone et leurs mélanges. Le premier monomère est présent à raison de 99,5 % à 75 % en poids et le second monomère est présent à raison de 0,5 % à 25 % en poids. Le terpolymère comprend: (i) un monomère primaire éthylène, propylène, butylène et leurs mélanges; (ii) un monomère secondaire alpha-oléfinique ayant de deux à dix atomes de carbone et des mélanges de tels monomères; et (iii) un monomère tertiaire alpha-oléfinique ayant de deux à dix atomes de carbone et leurs mélanges, le monomère primaire étant présent à raison de 50 % à 99 % en poids et les monomères secondaire et tertiaire à raison de 0,5 % à 49,5 % en poids. L'homopolymère est le polyéthylène, le polypropylène et le polybutylène.
