3 kinds of plasticizer DBP, DEHP, and DEHA in food contact PVC packaging were determined using GCMS method. The migration of the plasticizers into oil-type foodstuff simulants at high temperature was studied by combining GC-MS and gel permeation chromatography (GPC). The results indicated that 3 kinds of plasticizer exist in the food contact PVC with different contents; the existing plasticizers can easily migrate into oil-type food simulants quickly under high temperature (80 ℃ , 100 ℃ ), and the amount of migration exceeds the required limited quantity of 1. 5 mg / kg in EU; moreover, the migration quantity increases with time extending.
