CORONA TREATERS Unit

Vishva GlobalX is manufacturing and supplying the best quality corona treaters. Our VELOTREAT series of Corona treating equipment increase the surface energy of films, foils, and paper to improve the wettability and adhesion of inks, coatings and adhesives. The Corona Treatment method is widely used nowadays to increase the surface tension of the films. Treatment of plastic film is done by passing the film through the corona discharge created between electrodes and dielectric covered (Silicon Sleeve) Earthed roller. As the film passes through the corona discharge, molecules of the surface gets oxidises which has more surface tension. The corona discharge between electrode and roller is visible by violet colour flame between them. Treatment power purely depends on Film type, Film width and machine line speed.
