Title
(EN) GAS BARRIER COMPOSITIONS HAVING IMPROVED BARRIER PROPERTIES
(FR) COMPOSITIONS DE BARRIERE CONTRE LES GAZ AUX PROPRIETES DE BARRIERE AMELIOREES
Abstract
(EN) Gas barrier coating compositions are provided which include a polyamine component, a polyepoxide component and a hydroxy-substituted aromatic compound that is present in an amount sufficient to provide a gas barrier coating having an oxygen permeability less than or equal to 75 percent of the oxygen permeability of the same composition without a hydroxy-substituted aromatic compound. Also provided is a multi-layer packaging material having at least one gas permeable packaging material layer and at least one gas barrier material layer formed from the gas barrier coating composition. Sealable containers are also provided.
(FR) L'invention concerne des compositions de revêtement formant barrière contre les gaz contenant un constituant polyamine, un constituant polyépoxyde et un composé aromatique à substitution hydroxy présent en une quantité suffisante pour constituer un revêtement faisant barrière aux gaz et présentant une perméabilité à l'oxygène inférieure ou égale à 75 % de la perméabilité à l'oxygène de la même composition sans composé aromatique à substitution hydroxy. L'invention concerne également une matière d'emballage multicouche comportant au moins une couche de matière d'emballage perméable aux gaz ainsi qu'au moins une couche de matière faisant barrière contre les gaz formée à partir de la composition de revêtement formant barrière contre les gaz. L'invention concerne également des récipients pouvant être fermés hermétiquement.
