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. 〖JP2〗The evaluation system was verified. The results showed that this system can intuitively and reliably evaluate UV-shielding performance of transparent food packaging materials.
