Patent ID: 6960393

Claim:
A barrier film for limiting transmission of oxygen and moisture there-through comprising: (a) a polymer substrate having a first vacuum-formed plasma-treated surface; (b) a vacuum-deposited, first radiation-polymerized acrylate monomer film having first and second surfaces, the first surface of the first polymerized film being disposed on the first surface of the first plasma-treated surface of the polymer substrate; (c) a first inorganic layer having first and second surfaces, the first inorganic layer being disposed on the second surface of the first polymerized film; and (d) a vacuum-deposited, second radiation-polymerized acrylate monomer film having first and second surfaces, the first surface of the second polymerized film being disposed on the second surface of the first inorganic layer; wherein the second surface of the second polymerized film is a vacuum-formed plasma-treated surface.
