Abstract
A method for treating a flexible plastic substrate is provided herein. The method includes establishing an atmospheric pressure plasma beam from an inert gas using a power of greater than about 90W, directing the plasma beam toward a surface of the flexible polymer substrate, and scanning the plasma beam across the surface of the polymer substrate to form a treated substrate surface.
