A series of food safety incidents have caused widespread concern over the safety of plasticizer. Three phthalates (dibutyl phthalate (DBP), bis(2-ethylhexyl) phthalate (DEHP), di-n-octyl phthalate (DOP)) and a new environmental plasticizer acetyl tributyl citrate (ATBC) are commonly used in inks. Gas chromatography (GC) was used to measure the migration of four plasticizers from inks in lad-made printing paper to food stimulant (Tenax) at different temperature (50°C, 70°C and 100°C), different paper weight (240 g/m2 and 400 g/m2) and the different initial content of plasticizers. The results show that the lab-made printing paper can stimulate the real paper packaging with inks and the migration of plasticizers from inks depends on the diffusion and partition coefficients. The migration behaviour is significantly affected by the temperature and paper weight. Maximum migration increases with increasing temperature and decreasing paper weight.
