摘要

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.
