Generator CG2000 Series (CE)

Corona Application

Corona treatment is known as dielectric barrier discharge. It is mainly used for surface treatment of

plastic film or plastic sheet. Before ink printing, laminating, blowing, coating, gluing, material

modification, polymerization, film metallization, casting and adhesions of the materials, in order to

make the surface have stronger adhesion (i.e. higher dyne level), and prevent the printing and gluing

from fading, dropping and other poor effects, it is necessary to use corona surface treatment.

Corona Principle

The principle of the corona is to use high-frequency and high-voltage to generate corona between the

discharge electrode and the corona roller to form a low-temperature plasma area. Through the air ion

ization between the two medium, ozone is produced. Ozone is an oxidant, which can immediately change

the molecular structure of the plastic surface and make it from non-polar to polar. At the same time,

the corona will make the surface of the material have small and uneven holes to rough the surface and

enhance the surface activity, after the surface tension is increased, so the ink, glue, etc. can deeply

penatrate into the material because of treatment so it achieves the desired printing and gluing effects.
