摘要
聚偏氯乙烯 (PVDC)已广泛用于肉食品的包装。考察了γ -射线辐照对PVDC薄膜的力学和热性能以及溶解性能等的影响。在辐照剂量R≥ 10kGy时 ,PVDC产生辐射交联 ,PVDC膜的拉伸性能、撕裂性能、热收缩性能、热稳定性能和色泽受R的影响较明显 ;R <10kGy时 ,PVDC膜受R的影响甚微。
Poly(vinylidene chloride)(PVDC) film has been widely used in meat food packaging. Mechanical,thermal properties and solubility of γ-ray irradiated PVDC film were investigated. Results showed that when radiation dose R ≥10 kGy, PVDC could be crosslinked and it had an evident effect on tensile, tearing, shrinkable properties and heat stability as well as colour of the film with the increasing of R ; when R <10 kGy, it had little effect on properties of the film.
