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.
