1. Equipment Preparation: A specially designed corona treatment equipment is used for corona treatment. This equipment is a corona generator capable of generating high voltage.
2. Sheet Preparation: PP corrugated sheets should be cleaned and dried before processing. This step ensures that any dirt, oil or other residues on the plate are removed.
3. Feeding of the Sheet: A system is created where the sheets can be fed into the corona processing equipment in a uniform manner. This ensures fast and stable processing of the boards.
4. Implementation of Corona Treatment: After being fed into the corona treatment equipment, the sheets pass into the corona cavity created by the high voltage generator. The corona cavity contains a high energy electric current.
5. Surface Ionization The high energy electric current in the corona cavity causes ionization of molecules on the plate surface. This ionization increases the surface tension and creates polarity.
6. Controlling Surface Tension: The polarity created by ionization improves the adhesion properties of the sheet surface. This ensures better adhesion in printing, painting or coating processes.
7. Post-treatment Controls: After the corona treatment is completed, the effectiveness of the treatment is checked by surface tension tests on the sheets. These tests verify that the post-treatment surface tension is at the desired level.

Corona treatment is important to achieve better results in printing, coating and other surface treatments of PP corrugated sheets. The treatment increases the surface tension, making the sheet surface more easily machinable and providing the desired adhesion properties. In this way, the sheets can be used to achieve better results in different applications.
