Jeff Opad, V.P. of sales and marketing at Pillar Technologies, confirms converters' demand for a flexible corona treating approach—particularly in the form of "convertible" or "universal" systems—solidly outweighs extruders' demand.

Marc Nolan, sales manager at Sherman Treaters, views the convertible unit—one that affords transitioning between a bare roll and a covered roll system—as a practical system for converters having to deal with many variations in their converting process. In systems that include a "true dual dielectric," however, he believes the corona can be weakened because the corona power has to pass through two insulating materials and the web itself.
