Title
(EN) PAPER AND CARDBOARD PACKAGING WITH BARRIER COATING
(FR) EMBALLAGE EN PAPIER ET CARTON COMPORTANT UN REVÊTEMENT BARRIÈRE
Abstract
(EN) Described is paper or cardboard packaging produced from mineral oil contaminated, (e.g., recycled) paper, wherein the packaging includes a barrier layer obtainable by applying an aqueous polycarbonate dispersion. The barrier layer may be situated on one of the surfaces of the packaging or form one of multiple layers of a multilayered packaging coating or be situated as a coating on one side of an inner bag situated within the packaging
(FR) L'invention concerne un emballage en papier ou carton produit à partir de papier contaminé par de l'huile minérale (par exemple recyclé), lequel emballage comprend une couche barrière pouvant être obtenue par application d'une dispersion aqueuse de polycarbonate. La couche barrière peut être située sur une des surfaces de l'emballage, former une des multiples couches d'un revêtement d'emballage multicouche ou être située sous la forme d'un revêtement sur un côté d'un sac intérieur situé à l'intérieur de l'emballage.
