研究了PVC密封垫产品中常用原料助剂对蒸发残渣卫生性能指标的影响。结果表明，原料助剂的添加对接触水性和低乙醇食品的PVC密封垫产品的蒸发残渣影响较小；添加的CaCO-3填料对乙酸蒸发残渣影响明显， DINCH为增塑剂制备的PVC密封垫乙酸蒸发残渣值最低，ATBC为增塑剂制备的PVC密封垫正己烷蒸发残渣值最低。

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.
