The invention relates to an at least partially biodegradable multilayered material formed by the combination of: a) at least one first layer (A) of a first material predominantly based on at least one natural polysaccharide; b) at least one second layer (B) of a second material comprising a mixture based on at least one natural polysaccharide and at least one synthesis polymer selected with mechanical properties superior to those of the natural polysaccharide in such a way as to obtain a multilayered material having mechanical properties superior to those of the first layer. The invention also relates to at least partially biodegradable materials.
L'invention concerne un matériau multicouches au moins partiellement biodégradable formé par la réunion : a) d'au moins une première couche (A) d'un premier matériau à base majoritairement d'au moins un polysaccharide naturel ; b) d'au moins une deuxième couche (B) d'un deuxième matériau comprenant un mélange à base d'au moins un polysaccharide naturel et d'au moins un polymère de synthèse choisi avec des propriétés mécaniques supérieures à celles du polysaccharide naturel de manière à obtenir un matériau multicouches présentant des propriétés mécaniques supérieures à celles de la première couche. Matériaux au moins partiellement biodégradables.
