Abstract

Se describe una película de capas multiples, termoplástica, termocontraíble biaxialmente orientada, que comprende una capa central (A) la cual incluye uncopolímero de etileno-alcohol vinílico (EVOH): una primera capa externa (B), la cual incluye unh omo o co-polímero de etileno; y una segunda capa externa (c)que puede ser igual a - o diferente de - la primera capa externa (B), que incluye un homo - o co-polímero de etileno, en donde la citada película ha sidobi-axialmente orientada a unarelacio n de orientacion en la direccion longitudinal que es superior a 4:1, con preferencia mayor que4.5:1 con preferencia de al menos 5:1 y a una relacion orientada en la direccion transversal que supera de 4:1 con preferencia, que es mayorque4.5:1 con ma yor preferencia de por lo menos 5:1. Dicha película se obtiene mediante un proceso, que comprende la extrusion por fusion de los polímeros de lapelícula a través de un troquel plano y la orientacion de la lámina fundida obtenida enforma simultánea e n las direcciones longitudinal y transversal medianteun tensor simultáneo.
