PROBLEM TO BE SOLVED: To provide a medical transparent packing material capable of simultaneously materializing both photodegradation prevention of a content and visibility securement of the content.SOLUTION: A medical transparent packing material includes a base material layer, a gas barrier layer containing silicon oxide, an ultraviolet absorption layer, and an adhesive layer, in this order. The ultraviolet absorption layer contains a benzophenone-based ultraviolet absorbing agent and a coloring agent. In the medical transparent packing material, a light transmittance of a wavelength of 380 nm is ≤20%, a light transmittance of a wavelength of 450 nm is ≤20%, and a light transmittance of a wavelength of 600 nm is ≥60%. |
