The invention relates to a scintillator packaging thin film, comprising a protective layer, which is positioned at the outmost layer of the packaging thin film; a waterproof layer, the water vapor penetration rate of which is not more than 0.1g/m2.day-1, X ray absorption rate of which is not more than 5% and which is positioned at the inner side of the protective layer; a light-absorbing isolation layer; and a non-isotropic optical reflection layer, which selectively reflect visible lights, so that abnormal phenomenon such as crumple, bubble, etc., generated owing to particles and packaging on the surface of the scintillator, does not impact on the imaging of a X ray detector.
