摘要
对21种透明食品包装材料进行了透射光谱分析,获得了透射光谱。将紫外线透射比评价模型引入到了透明包装材料防紫外线性能的评价中,并对该评价体系进行了验证。结果表明,该评价体系能直观、可靠地评价透明包装材料防紫外线的性能。
Transmission spectra of 21 kinds of transparent food packaging materials were obtained through ultraviolet（UV）scanning.UV transmission evaluation model was introduced into evaluation of UV-shielding performance of the transparent packaging material.The evaluation system was verified.The results showed that this system can intuitively and reliably evaluate UV-shielding performance of transparent food packaging materials.
