Effect of additives on PVC gasket evaporation residue amount was investigated. The results showed that, the use of additives has less effect on PVC gasket evaporation residue when contacting water-based and low-ethanol food; it has obvious impact on acetic acid evaporation residue when using additive CaCO-3. PVC gasket has the least acetic acid evaporation residue which using plasticizer DINCH, and the least hexane evaporation residue when using plasticizer ATBC.
