摘要
讨论了PEC PVDP复合包装材料的辐射效应 ,在辐射剂量 5Rad 30KGY剂量真空和有空气辐射条件下 ,材料的密度、透气性没有明显改变 ,抗拉强度及凝胶数没有明显改变 ,经IR和UV等分析方法检测 ,没有发现明显的变化 ,说明可以作为辐射食品的包装材料使用。
The radiation effect of PEC PVDP composite materlal is studied in the paper.In the condition of 5Rad 30KGY radiological dose and vacuum(atmosphere),the density and air permeability doesn't change obviously,the intensity of resisting pulling and the number of jel also doesn't change.Through detection of IR and UV,the material has changed.It proves that the material can be used as packing material of radiation food.
