Abstract

Summary form only given. Adhesion characteristics of tin plate with polymer-coating is investigated after atmospheric plasma treatment. We have used atmospheric dielectric barrier discharge plasma for treatment and contact angle, XPS, SEM for surface analysis. It is observed that contact angle is decreased remarkably. It indicates surface energy is increased, that provides more driving force for adhesion. And we have observed that carbon ratio is decreased and at the same time oxygen ratio is increased. It is thought to be a carbon cleaning effect and oxidation effect which makes functional groups on the tin plate. It may cause the increase of adhesion. We have observed the enhancement of adhesion between tin plate and polymer coating as a result of taping test. Besides, the number of pin hole, which causes elusion of metal contents, is decreased. Therefore plasma treatment can be effective tool for adhesion enhancement of tin plate used for cans which contain edible foods
