Corona treatment is a surface electric discharge process that enhances the adhesion of plastic or metallized films. Most plastic films (such as polyolefin films) are non-polar polymers with low surface tension. Corona treatment is used to increase the surface energy of these films, as known inks and adhesives cannot adhere firmly to their surfaces in normal conditions.

- Corona Generator, CW1001-1003 The CW1000 series corona generator utilizes a resonant switch, along with reliable integrated circuits and power devices. It efficiently converts grid electricity into high-frequency, high-voltage AC using a bridge inverter circuit comprising power tubes. This high-voltage AC is then applied to the surface of the treated material through dedicated discharge electrodes. When polymers and other treated objects are subjected to discharge, their surfaces generate polar groups. This results in a strong ion impact, which roughens the material's surface, effectively enhancing the penetration and adhesion of ink and glue.

- Corona Generator, CW3002-CW3006 The low-power corona generator has wide application in modifying the surface of plastic films. Our corona generator converts grid electricity into high-frequency, high-voltage electricity, which is then applied to specialized electrodes to create corona discharge. This process enhances the surface energy and improves adhesion. Our corona generator has high operating frequency, stable and reliable performance, and is easy to operate, making it suitable for low-power corona treatment.

- Corona Generator, CW3008-3030 The medium-to-high-power corona generator operates by converting three-phase AC power into DC power and then using IGBT as the power converter to create a half-bridge inverter circuit. This generates a high-frequency, high-voltage AC of about 20kHz, which is boosted by a transformer to produce 15KV, 20kHz high-frequency, high-voltage electricity for the discharge frame. The corona generator boasts advanced technology, reliability, high working frequency, and high output power. It utilizes three-phase controllable rectification technology, allowing users to adjust the output power by controlling the rectification trigger angle α through a panel knob.
Corona treaters are increasingly used in various industries such as flexible packaging, batteries, aluminum foils, sheets, piping, cables, cups, and foaming materials. Corona treaters are especially indispensable in plastic extrusion, printing, lamination and coating processes.
