Effect Of Corona Treatment
Mar 30, 2018

Corona treatment on the plastic surface produced by the physical and chemical effects are complex, the effect is mainly through three aspects to control: ① specific electrode system, ② Guide roller on the material medium, ③ specific electrode power.

Because different chemical structures have different atomic bonds, the effect of corona treatment on plastics varies with the chemical structure of plastics. Different kinds of plastic need different intensity corona treatment. Practice has proved that BOPP film in the production will also have a structural state changes, in a few days, the polymer changed from amorphous to crystalline shape, thus affecting the effect of corona treatment.
