The difficulty in getting inks to bond with a wide range of plastics is well known. Plasma Surface Treatment improves adhesion on the material, stopping print rubbing off and improving the quality of the ink finish.
When inks do not adhere to components it is often because the surface is contaminated by additives which have risen to its surface or its inherently low surface energy.
In-line surface treating is performed immediately prior to printing and creates a high-energy surface, cleaned from contamination and functionalised with increased bonding sites for adhesion.
Treatment is effective on Polypropylene (PP), Polyethylene, (PE), Polyamide (PA), and Polycarbonate (PC), glass and metal surfaces. It improves ink adhesion with water based, solvent and UV inks and works effectively with all types of printing processes including digital ink jet, pad, screen, flexographic, and gravure printing.
The Enercon Blown-ion™ and Blown-arc™ plasma surface treaters can be configured to prevent the visual and material damage that can occur with flame treatment of plastics. They increase productivity of a printing process as they remove the need for chemical or solvent cleaning before print.
