Corona effect surface treatment machine FoamTEC

PP board is made of blended PP co-polymer and has one major disadvantage – low surface energy, resulting in poor surface adhesion for water-based adhesives and inks. Corona treatment systems by Tantec significantly increase surface energy and improve adhesion. Corona Treatment of Foam and Board. To optimize treatment and minimize waste it is important that the entire board surface is treated. To achieve this result, it is necessary to have the corona discharge around the board’s edge. Tantec solves this problem by increasing the thickness of the dielectricum layer, increasing the roller’s longevity and allowing corona treatment to the board’s edge. Increasing the insulation thickness will even out the discharge and ensure uniform treatment of boards up to 50 mm in thickness. The FoamTEC is available for single and dual sided treatment. Adjustable electrode which ensures max. flexibility. Electrode height adjustment with digital read-out. When treating corrugated board, it is important to limit the treatment inside the cavities to avoid loss of power and creation of ozone. The Foam TEC with thick insulation of counter electrodes limits treatment inside the cavities.
