Corona technology is widely accepted as a process for the surface treatment of plastics, paper and metal foil to improve the adhesion of inks, paints, bonding agent and coatings.

Corona treating is a very effective way to increase the surface tension of virtually any material. The result after corona treatment is a surface that is unchanged to the naked eye, but in fact is much more receptive to inks, coatings, and adhesives.

The material being treated is exposed to an electrical discharge, or "corona." Oxygen molecules within the discharge area break into their atomic form and are free to bond to the ends of the molecules in the substrate being treated, resulting in an increase in surface tension.
