Abstract

La présente invention concerne des compositions et des procédés permettant de former des revêtements barrières sensiblement biosourcés sur des substrats de papier et de carton. Les revêtements barrières biosourcés de l'invention comprennent une émulsion de biocire comprenant une ou plusieurs biocires, telles que la cire d'huile de ricin, formée par hydrogénation d'une huile biosourcée, telle que l'huile de ricin. La composition du revêtement barrière est formée par dispersion d'une émulsion de biocire dans une dispersion de support de polyacrylate et peut être appliquée sous la forme d'un revêtement, par exemple, sur du papier ou du carton, par exemple ceux constitués de fibres recyclées, à l'aide de procédés industriels classiques à des températures ambiantes.
