Abstract

Cette invention concerne une bande à multicouches co-extrudées (100) pour substrats tissés (200a, 200b, 200c) et sacs tissés (400). La bande à multi-couches (100) comprend une couche polymère intermédiaire (102) co-extrudée avec au moins une couche externe (104a, 104b) placée sur chaque côté de la couche polymère intermédiaire (102). Les couches externes (104a, 104b) sont co-extrudées à l'aide d'un matériau thermoscellable à basse température, de façon que les couches externes (104a, 104b) sur chaque côté de la couche polymère intermédiaire (102) aient les mêmes propriétés d'étanchéité.
