摘要: Coating compositions which have improved oxygen and flavor/odor barrier characteristics are disclosed. The coating obtained by a polymeric substrate with an aqueous solution of polyvinyl alcohol urea drying the at temperature sufficient to allow crosslink such that urethane linkages formed least between composition. Polymeric film structures including method making same also
