Improved wettability and adhesion of the adhesive! Corona treatment to enhance the substrate surface.
"Corona treatment" is a surface treatment technology that modifies the surface of substrates such as plastic films through corona discharge irradiation. By applying corona treatment, the surface of the substrate is modified, improving the wettability and adhesion of inks, coatings, adhesives, and other materials. Generally, plastic films have low surface tension, which often leads to issues such as poor adhesion during printing or coating. However, when corona treatment is performed, the surface tension of the substrate is significantly increased, enhancing adhesion. 【Features】 ■ Corona discharge irradiation ■ Significant improvement in surface tension of the substrate ■ Enhanced wettability and adhesion ■ Compatible with materials other than PET films ■ Capable of handling small lots *For more details, please refer to the catalog or feel free to contact us.
