Introducing Steraflex GIO: A New Standard in Low Migration Flexo Inks

We are proud to introduce Steraflex GIO, our latest innovation in low migration flexographic printing inks. Specially developed to meet the most stringent regulatory requirements, Steraflex GIO is fully compliant with the new German Ink Ordinance (GIO)—setting a new benchmark in both safety and performance.

With increasing regulatory scrutiny on food packaging inks, compliance and transparency are more important than ever. Steraflex GIO is free from intentionally added photo initiator 379, ensuring it aligns with the current and upcoming requirements under the GIO. This gives printers and brand owners peace of mind when producing packaging for more sensitive applications, particularly in the food and pharmaceutical sectors.

Moreover, Steraflex GIO is not just about compliance—it’s about performance. Formulated with a next-generation binder system, Steraflex GIO delivers enhanced adhesion across a broad range of substrates, from standard films to demanding label materials. Compared to its predecessor, this ink demonstrates significantly improved bond strength, even on low surface energy substrates, enabling more versatile applications without compromising on print quality or safety.
