Corona treatment
Wide range of products and services
Network of specialized partners
Corona treatment is a surface modification technique widely utilized in the industry to increase the surface energy of various substrates, thus improving their adhesion properties. At Glacon, we recognize the vital role of corona treatment in preparing materials for processes like adhesive bonding, coating, and laminating. By applying a corona treatment, we ensure that materials such as plastics, foils, and papers are more receptive to inks, adhesives, and coatings, significantly enhancing the quality and durability of the final product.
The science and application of corona treatment
Corona treatment involves the application of a high-frequency, high-voltage electrical discharge to the surface of a material. This process creates micro-etching on the surface, which leads to an increase in surface energy and, consequently, better wettability and adhesion of subsequent layers. Such treatment is particularly crucial for the adhesive bonding of materials that are naturally hydrophobic and difficult to bond, such as polyethylene and polypropylene. Our expertise makes us particularly adept at performing corona treatments as a preparatory step for hot melt coating. We also leverage this method before laminating processes. This ensures that even materials with low surface energy can be effectively combined with adhesives and coatings, resulting in products that meet the highest standards of performance and reliability.
