ABSTRACT:
A barrier film having excellent low oxygen permeability is provided and includes a flexible polymeric substrate having an adherent amorphous carbon coating. The coating is applied by generating a gas plasma from a hydrocarbon gas within a coating chamber such that ions in the gas plasma impinge upon the polymeric substrate. A barrier film having an ultra low oxygen permeability is produced by coating a second polymeric substrate over the amorphous carbon coating.
