Exposure Assessment for food contact materials

The presentation outlines why people involved in the Food Contact Material value chain may want to do exposure assessments, what is involved in creating an exposure assessment, and how the resulting exposure assessments can be used as part of a risk assessment to determine a basis for safety. The software used to do the exposure assessments is FACE

UV Inkjet Printing on Food Packaging: State of Art and Outlook

• Inkjet printing on packaging = answer to packaging trends• UV LM inkjet ink formulation  low viscosity for jetting• Thereby requires full conceptual development of LM ink concept• Monomers and photo-initiators need to be LM ink specific designed for combination of low viscosity and high curing degree• Dedicated LM inkjet ink technology can resul

Investigation of Printing Inks and Coatings Formulations for UV-LED Cure

• only a selected number of Photoinitiators work under LED• LED 365 shows the best results for a magenta ink.• A 3 level (6-2) DoE shows that DETX and TPO/BAPO are sufficient for a good cure• EMK has in most cases a negative impact on cure, maybe due to its high efficiency, and yellows to much in magenta at 3% content• DoE works good to predict rea

UV LED Curing in Low Migration Printing - Controlling the Variables

Once parameters for a low migration printing process are established, the most critical variable remaining is curing. Despite challenges for ink formulators, UV LED is the key curing technology eliminating this vulnerability. It is outlined, why UV LED curing due its unique properties is an enabling technology for printing within a tight operating
