EuPIA Migration Guidance
EuPIA to issue updated migration guidance including testing for Direct Food Contact applications
EuPIA AEWG (Analytical Expert Working Group) has updated its guidance on migration test methods for printed Food Contact Materials which identifies the suitability of extraction and analytical methods for evaluation of inks and varnishes printed on food contact materials and for the non-contact side of food packaging.
The EuPIA migration guidance acts for supporting converters and brand owners for the product safety of printed materials for NPH (Nutrition, Pharma and Hygiene) packaging applications. It provides a guideline of recommended tests that are deemed suitable for extraction or migration evaluation on sensitive product packaging, including food-safe products.
The guidance has been revised and adjusted to reflect changes in new NPH market applications. The guidance, which previously featured three Annexes (A, B, C), has now included two more annexes (D, E) for DFC applications, showing a list of typical indicative examples and a more specific description of test methods for these applications.
EuPIA AEWG (Analytical Expert Working Group) advises, that in all cases the description of the analytical tests should only be considered as a case of preliminary evaluation of raw materials formulated in inks and varnishes, hence suitable for a worst-case evaluation. It is not intended to be used for packaging compliance as the final evaluation of the migration compliance is the responsibility of the converter, not of the ink manufacturer.
The amended guidance on migration test methods is available to view and download now on the webpage of EuPIA.
Case of paper straws
As more and more consumers are adopting an “anti-plastic” movement mindset, paper straws are becoming an increasingly important alternative to the plastic straws. Paper straws can be categorized as DFC materials having an intentional short-term contact time. Indeed the printed paper straw is immerged in different types of beverages, cold or hot drinks, with various composition (for instance water, coffee, milk, tea, sodas, cocktails) and the use of it is generally not exceeding 1 hour. The details of the recommended testing conditions are described in the Annex E of the guidance.
