Abstract
A process for treating a surface of a substrate to improve the oxygen, carbon dioxide, flavor and odor gas barrier properties of the substrate with an organic acid having at least two acid substituents selected from the group consisting of a polybasic carboxylic acid, a polymer of an unsaturated carboxylic acid and a co-polymer of an unsaturated carboxylic acid, by applying the acid on to the substrate to form a layer, and exposing the layer to moisture. A variety of other types of additives may be included in the coating applied to the substrate with the acid including compounds of the formula R X Si(CH ) Y, a condensation catalyst, a solvent, and/or a filler.
