Resumen: Migration of non volatile compounds from twenty six PP films used as food contact materials has been studied in four simulants (ethanol 95% and 10%, acetic acid 3% and Tenax ®) and analyzed by UPLC-MS/QTOF. Seventy six compounds have been identified, where 76% of them were non-intentionally added substances (NIAS) coming from degradation of additives used, such as methyl or ethyl or hexyl-3-(3, 5-di-tert-butyl-4-hydroxyphenyl) from irganox 1076 and irganox 1010 degradation; or impurities such as N, N-bis(2-hydroxyethyl) amines, or compounds of unknown origin, like hydro-ceramides. The most common compounds found were glyceryl monostearate or monopalmitate, erucamide, irganox 1010, irgafos 168, irgafos 168 OXO, N, N-bis(2-hydroxyethyl) tridecylamine and N, N-bis(2-hydroxyethyl) pentadecylamine. Six films didn''t comply with the European Regulation Nº 10/2011/EU, where irganox 1010 and the group of N, N-bis(2-hydroxyethyl) amines exceeded their SMLs. Other films surpassed the maximum concentration recommended by Cramer for the compounds of class II (degradation products) or III (amide compounds) when ethanol 95% was used as simulant.
