Abstract

The use of an aqueous Solution comprising at least one polyanion and at least one high molecular weight polyethyleneimine is described, for providing oxygen barrier properties to a polymer film. The polyanion is a polymer comprising acid groups neutralized with a base selected from the group consisting of inorganic bases and monovalent organic bases and having a weight average molecular weight of at least 10000 g/mol.
