Investigation into the migration of nanoparticles from plastic packaging materials containing carbon black into foodstuffs

Carbon black was investigated to assess and quantify the possibility that nanoparticles might migrate out of plastic materials used in the food packaging industry. Two types of carbon black were incorporated in low density polyethylene and polystyrene. The samples were exposed to different food simulants according to the EU Plastics Regulation 10/2011.
At a detection limit of 12 µg kg−1, carbon black did not migrate from the packaging material into food simulants. From the findings it can be concluded that carbon black does not migrate into food once it is incorporated into a plastics food contact material (Food Additives & Contaminants: Part A, 8 August 2014).
