FAQs About Surface Treatment for Foils, Metals, and Metallized Materials
How does surface treatment improve print and laminate quality on foils?
Corona or plasma treatment improves ink anchorage, eliminates ink beading, and reduces coating defects. It also enables adhesives to bond more consistently, resulting in stronger lamination performance and improved visual clarity, especially in high-gloss or reflective packaging applications.
Will corona or plasma treatment damage thin foils or metallized layers?
No, not when properly configured. Pillar Technologies offers high-precision control of power output and electrode design, ensuring effective treatment without pinholing, wrinkling, or overheating delicate substrates.
Can surface treatment help with barrier performance?
Yes. While surface treatment does not change the inherent barrier properties of the metal layer, it enables better adhesion of coatings, sealants, or laminates that can enhance moisture, oxygen, and light resistance in the final package structure.
Can these systems be integrated into existing foil converting or laminating lines?
Yes. Pillar Technologies’ corona and plasma systems are modular and designed for seamless integration into existing lines. Whether you're treating narrow web metallized films or wide rolls of foil, we’ll help you find a solution that fits your application and process speed.
