Effect of Resin Additives on Corona Treatment of Polyethylene

Abstract
A systematic study was made of seven common polyolefin resin stabilizers. Surface analysis techniques were used to characterize the surfaces of films containing these additives. Films were evaluated before and after corona treatment. Results of this study showed that a surprising number of additives are surface active. In some cases these additives have a dramatic effect on the surface chemistry produced by corona treatment, yet they do not affect subsequent ink adhesion. Conversely, an additive may not significantly affect the corona treatment chemistry but yet still reduce the adhesion performance of the film product.
