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