The Gallus Labelfire is now available in a low-migration version, enabling the production of food-grade packaging in accordance with EU regulations and the Swiss Ordinance on Commodities (Swiss Ordinance).
Gallus and Heidelberg have developed a special ink series that is suitable for packaging that comes into contact with food. The drying and curing technology of the Labelfire has also been adapted to comply with European regulations.
Thomas Schweizer Head of Business and Product Management at Gallus Ferd. Rüesch AG.
Gallus Labelfire Low Migration means that label and packaging printing is possible with UV inkjet using specially developed Saphira UVLM inks. These are designed to meet food industry standards. In addition, the digital printing press is equipped with a multi-stage drying system.
Compliance with the relevant legislation is a prerequisite for the food-grade production of labels and packaging.
Immediately after printing, the substrate web is fed into a dryer with an inert chamber. The almost complete exclusion of oxygen optimizes the curing performance of the inks. An optional UV booster then enhances the drying of the inks at higher printing speeds.
In addition to these new drying units, the Gallus Labelfire Low Migration is equipped with UV and oxygen sensors that display the production parameters.
Our UVLM inks comply with:
At higher pressure speeds, the drying unit is additionally supported by a booster with four nozzles.
Uwe Alexander, Digital Product Manager, Gallus
The new drying unit has two inert chambers and is equipped with UV and oxygen sensors.
