Abstract
An improved oxygen barrier layer for coating a substrate, such as a polymeric film. The oxygen barrier is a layer of cross-linked polyvinyl alcohol and glyoxal, which exhibits improved barrier characteristics to the transmission of oxygen. The oxygen barrier is produced by coating a solution of polyvinyl alcohol, glyoxal and tensoactive agent onto at least one side of a substrate adapted for receipt of such solution. The polyvinyl alcohol is thereafter cross-linked in the absence of a catalyst to provide the oxygen barrier.
