In for a Treat

Following film's footsteps

A more active facet of surface treating technology can be found in suppliers' efforts to educate package printers about treating the multiple—and growing—personalities of films.

Printers face a slightly different surface treatment scenario for films than extruders—an important notion as more and more printers shift away from purchasing pretreated films. "Films are more difficult to treat off-line than during extrusion," explains Jeff Opad, VP of sales and marketing at Pillar Technologies, Hartland, WI.
