Food contact polyvinyl chloride (PVC) materials were characterized and analyzed by FTIR. The overall migration of chemicals from PVC under different conditions was studied by evaporation residue method. The results indicated that a high quantity of non-volatile chemicals including plasticizers of phthalate esters or fatty diacid esters existed in the PVC products, which can easily migrate into oil-type food simulates under high temperature; The sequence of migration quantity is as following: 95% ethylalcohol≥hexane＞water≈4% acetic acid≈20% ethyl alcohol; the quantity of migration is relatively large under high temperature; and the migration quantity increased with time extending.
