Plasma surface treatment machine

for filmfor the printing industry

To be able to print and coat plastic films, the surface tension of the material must first be increased. In addition, coating requires long-term stability of surface activation. In the methods previously available, such as corona treatment or flame treatment, surface tension decreases after a short time. Pretreatment with the Openair® process results in reliable surface activation of the plastic films – activation that displays outstanding long-term stability. Inks and coatings are optimally absorbed. Openair® film systems use special slot nozzles. They it make possible to reliably treat film with atmospheric-pressure plasma over any width. An additional positive side effect of treating the plastic with Openair® plasma is a noticeable anti-static effect. Openair® plasma systems for the treatment of plastic films – advantages and properties: Pretreatment with long-term stability due to high surface activation Possibility of partial activation Additional cleaning effect of additives Anti-static effect Treatment width per nozzle = 25 mm Single-sided pretreatment High processing speeds
