It is well known that commercial ozone is mainly produced by UV lamps and corona. Today we will talk about the application and disadvantages of corona treatment.The role of corona treatment in printingCorona treatment is destroying the molecular structure of the substrate （such as plastic film ）by corona discharge. The surface is oxidized and polarized in minutes, and the ion shock erodes the surface, so as to increase the adhesion of the substrate surface. Finally, the printing ink can be well attached to the surface of the substrate.
Disadvantages of corona treatment
Corona treatment brings great convenience for printing. but a large amount of ozone be released in the process, which greatly reduces the air quality of the production workshop. When first arrive at the production workshop, you can obviously feel uncomfortable and pungent. In the long run, the smell even endanger the health of the staff.
