The residuals of printing ink components were determined in 94 samples of packaging materials commercially used in the Czech Republic for food packaging. Tested samples included printed polyethylene and polypropylene films, coextruded and laminated films, paperboard beverages boxes, foils for thermo sealing of polystyrene cups and polypropylene cups. Printing ink components were extracted with diethylether, then separated and determined using gas chromatography coupled with a mass spectroscopy detector. Fifty compounds potentially originated from printing were isolated, identified and quantified. No acute health risk for food consumer was identified even though several findings of higher levels of photoiniciators (e.g. in PET films for thermo sealing of polystyrene cups) as well as plasticizers (acetyl tributyl citrate, tributyl aconitate, 2-butoxyethyl oleate and 2-ethylhexyl diphenyl phosphate in coextrudet films) should be completed with information on their real migration into food and or food simulants for a proper safety evaluation.
