摘要
电离辐照处理包装材料已经成为现代包装杀菌最普遍的方法,它能够使塑料包装材料发生交联和降解反应。从电离辐照对食品包装杀菌的意义出发,分析电离辐射影响聚合物性能的机理;最后重点阐述电离辐射对几种商业用塑料包装材料的机械性能、塑料成分迁移量、阻隔性能及感官性能影响。
Ionizing irradiation has become a modern packaging sterili zation in the most common method,it can make the plastic materials cross-linking and degradation. From the meaning of ionizing irradia tion to food packaging sterilization, analyzing the effects of ionizing radiation on the performance of polymer mechanism, and discussion the comparisons betweenT-irradiation and electron beam irradiation; Finally,interpretering the effects of the ionizing radiation of several commercial plastic packaging materials on their performance emphat ically. According to the actual needs,make a good use of irradiation sterilization technology.
