Abstract
A barrier film including a substrate; a base polymer layer adjacent to the substrate; an oxide layer adjacent to the base polymer layer; a adhesion-modifying layer adjacent to the oxide layer; and a top coat polymer layer adjacent to the adhesion-modifying layer. An optional inorganic layer can be applied over the top coat polymer layer. The inclusion of a adhesion-modifying layer provides for enhanced resistance to moisture and improved peel strength adhesion of the top coat polymer layer to the underlying barrier stack layers.
