Although the organic solvents in the Received in revised form adhesive, printing ink, and diluter are not in direct contact with the food, they may migrate through the 22 April 2015 films under certain conditions, potentially threatening human health. In this study, gas chromatography Accepted 26 April 2015 was used to analyze the migration rate of residual toluene from laminated films into four food simulants, Available online 19 May 2015 namely isooctane, 50% ethanol, 3% acetic acid, and 10% ethanol. The effect of different parameters on toluene migration was
