CA 2352393

A process for manufacturing a bi-axially oriented, heat-shrinkable, polyolefin, multi-layer film comprising a first layer (A) comprising an ethylene-.alpha.- olefin copolymer and a second layer (B), which is an outer layer, comprising an ethylene or propylene homo- or copolymer, which process comprises melt extrusion of the film polymers through a flat die and orientation of the obtained cast sheet simultaneously in the longitudinal and the transversal directions by a simultaneous tenter.

L'invention concerne un procédé de fabrication d'un film multicouche de polyoléfine thermorétractable et à orientation bi-axiale comprenant : une première couche (A) formée d'un copolymère éthylène- alpha -oléfine ; et une deuxième couche (B), qui est une couche extérieure, formée d'un homo ou co-polymère d'éthylène ou de propylène. Le procédé consiste à effectuer une extrusion à l'état fondu des polymères du film dans une matrice plate, puis à orienter la feuille coulée obtenue simultanément dans les directions longitudinale et transversale au moyen d'une rame simultanée.
