Abstract
An apparatus and method for depositing an ultra-thin inorganic coating on to a packaging film substrate is disclosed. Flame pretreatment enhances the quality of the inorganic coating. Multiple coating layers may be deposited onto the substrate by passing the substrate over various one or more flame head configurations in either a stand-alone or in-line manufacturing environment.
