In response to new demands in food label and packaging Flint Group announces the worldwide introduction of a brand new ink series - Flexocure ANCORA.

Flexocure ANCORA is a high performance low migration UV flexo ink range designed to provide a very low migration potential in compliance with the demands of Swiss Ordinance on Materials and Articles (SR 817.023.21).

Flexocure ANCORA provides excellent press performance at high printing speeds, very good adhesion and excellent scratch resistance on synthetic substrates.

“We have been working hard on this development for some time and are very pleased with the results,” Niklas Olsson, global brand manager, said. “To be able to offer a UV flexo ink with high performance on press, excellent colour strength and adhesion while still meeting lowest possible migration limits, is exactly what our clients have been looking for – which is, no compromise in performance due to low migration properties.”

UV inks consist of a range of different ingredients, with the photo-initiators and monomers commonly used being considered as potential migrating substances. When formulating UV curing products for food labels and packaging, careful consideration in regard to ingredients must be made, in order to optimize both overall press performance and produce an ink that can be used on food packaging while meeting stringent requirements.

“For this new ink series we have conducted migration tests at several independent institutes, as well as in our own analytical laboratories,”Christina Eriksson R&D manager of Flint Group Narrow Web, explained. “The migration measurements have indicated, that when correctly applied on suitable packaging structures migration levels with Flexocure ANCORA are below currently accepted limits. This was verified based on the standard migration test method using the food simulants 95% ethanol and Tenax as set out in Commission Directive 97/48/EC. Furthermore we have the confirmation of leading end users that the ingredients used in Flexocure ANCORA are meeting their company guidelines.”

“All analytical results have been confirmed by printers who applied Flexocure ANCORA on actual final packaging constructions,” Mr. Olsson concluded. “The migration limits are below stipulated limits. Looking at all the tests and the practical results with Flexocure ANCORA, we can say that this ink series offers a unique combination of low migration and high performance for UV flexo printing in the food segment.”
