Information Note: Inks and Coatings for High Temperature Applications
Over the past years, food packaging has been developed with several additional features/functions, one of them being that packaging is more and more often used as a container in which to heat or even bake the food (“ready-to-heat”). This information note describes the risks associated with the use of inks and coatings for food packaging intended to be exposed to high temperatures. In addition, it points out the reasons why an independent rigorous risk assessment must be carried out by the converter to ensure safety-in-use of the printed packaging.
EuPIA Guidance for Risk Assessment of Non Intentionally Added Substances (NIAS) and Non Listed Substances (NLS) in printing inks for food contact materials
Besides intentionally added substances (IAS) printing inks may also contain small amounts of substances, which are non-intentionally added (NIAS) and which may also not be listed in any official substance list approved to formulate food-packaging printing inks.
This document provides guidance for the risk assessment of non-intentionally added substances (NIAS) and non-listed substances (NLS) migrating from printing inks used for food contact materials.
EuPIA Guidance on Migration Test Methods for the evaluation of substances in printing inks and varnishes for food contact materials
In the absence of harmonised test methods for non-plastic Food Contact Materials (FCMs), the conditions used in the Plastics Regulation are often also applied to non-plastic FCMs. However, plastic simulants and/or conditions may cause physical damage or changes to the non-plastic FCM leading to erroneous results. This is also true for printing inks. Hence, testing conditions better suited to the specificity of each FCM need to be proposed. This document is aimed at providing specific guidance for printing inks for FCMs.
Nanoscale pigment particles: Analysis of the migration behaviour from printing ink layers of printed food packaging into food
The German Paint and Printing Ink Association VdL commissioned a study investigating the migration of nanoscale pigment particles from printing ink layers of printed food packaging into food. Following the wide range of analytical methods used in this study, no migration of nanoscale pigment particles could be detected from ink layers of printed food packaging into food. Therefore exposure of consumers to nanoparticles from the dried and cured ink layers may be excluded.
