Corona Treatment is a well known process used in the extrusion and converting industries. Corona treater electrodes, roll coverings and power supplies can be optimized to meet the challenges of printing, coating, laminating, blown film, and cast film applications. Below is a sampling of typical applications where corona treatment is used to promote adhesion.
Converting Film With Corona, Plasma & Flame Surface Treatment
Flexible packaging converters and label printers know that almost all engineered films have nonporus surfaces with inherently low surface energy. These films are surface treated at the time of extrusion, but also require in-line treatment at the time of conversion.
