Zusammenfassung:	A multilayer film including an odor barrier layer having sound dampening properties is provided. The odor barrier layer is formed from a polyamide modified with a functionalized vinyl-bond rich triblock copolymer. On décrit un film multicouche comprenant une couche barrière anti-odeurs présentant des propriétés d'isolation acoustique. La couche barrière anti-odeurs est constituée d'un polyamide modifié avec un copolymère triséquencé fonctionnalisé, riche en liaisons vinyliques.
