What are the advantages and disadvantages of corona treatment

Oct.26.2022

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 printing：Corona 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.
