Corona treated options
Better adhesion for printing, coating and lamination.
We offer both single-sided and double-sided corona treatment for films, tailored to your requirements. We can add corona treatment to your materials as part of our Trade Conversion Services, enhancing the surface to improve adhesion for printing, coating or lamination.
Corona treatment increases the surface energy of plastic films, helping inks, coatings and adhesives adhere more effectively. The result is stronger bonds, improved print quality and a consistent finish: ideal for packaging, labelling, printing, laminating and converting where reliable performance and a high-quality appearance are essential.
