Corona Treater System


Corona treatment technique is a surface modification system. This system used to optimize the adhesion properties of the material and to ensure bonding with inks, coatings, and adhesives. The surface treatment is essential for the plastic films and fabrics because the surface tension of these materials is low to permit good wetting by flexographic inks.

A high-frequency charge provides an efficient way of increasing the adhesion and wettability of a plastic surface. A surface tension of the fabric respective to inks increased by the following methods: inducing a molecular change in the surface of the films and exposing the air at the material's surface to a high voltage electrical discharge called a corona. In the corona treatment plastic film/fabric is passed from free roller through the airgap between electrode and the silicone roller.

Corona treatment is a surface treatment of profiles, treatment of cables, injection of molded parts and used in the plastic film, automotive, extrusion, and medical industries.
