Introduction Corona treatment is widely used to improve adhesion on plastic films. When applied correctly, it modifies only the outer molecular layer of the substrate,... Continue reading
Introduction Corona treatment is essential for improving ink, coating, and adhesive adhesion on plastic films. However, more treatment is not always better. In many production... Continue reading
Introduction Many converting operations face the same frustrating situation:corona treatment works perfectly on polyethylene (PE), but struggles—or completely fails—on polypropylene (PP) and polyethylene terephthalate (PET).... Continue reading
Introduction Corona treatment should produce a stable, uniform electrical discharge across the full width of the web. When that discharge becomes unstable—visible sparks, crackling sounds,... Continue reading
How long does corona treatment last? Corona treatment can last from weeks to several months under ideal storage conditions. However, factors such as contamination by... Continue reading
1. Uneven Electrode-to-Substrate Gap Corona treaters rely on maintaining a precise, uniform gap between the electrode and the substrate across the full web width. Over... Continue reading
