In the final step in the manufacturing process, glass is coated to avoid damage and scratches on bottles due to friction during transport.
Afterward these glass bottles are generally printed in a screen printing process. The type of coating that was performed during manufacturing determines if the printing ink used can bond well. To ensure a strong bond and even coloration, especially on polymer coating, plasma activation is required to increase surface tension.
Thanks to its robust jet systems and simple inline integration, Openair-Plasma® technology offers an optimal solution for creating the necessary surface activation on the glass containers.
