FoodClass® - UV based coatings in food packaging printing
Packaging in the direct or indirect food contact must not transfer any constituents to food in quantities, which could a) endanger human health, b) unacceptably change the food composition or c) bring about deterioration in the organoleptic characteristics thereof.
In this context, we see the appropriate selection of all raw materials, as they must comply with relevant specifications and applicable regulations. In contrast to dedicated water-based coatings, UV coatings can be used for the indirect food contact only.
The safest way to apply UV coatings on food packaging is to provide a (functional or absolute) barrier. In this case, the folded box acts as a secondary packaging. However, if there is no barrier available, only suitable UV coatings may be used which comply with applicable food packaging regulations.
