To provide a transparent packaging bag for transparent exterior packaging, using a packaging material which combinedly has oxygen barrier and UV-screening properties and controls the occurrence of pinholes during transportation processes.

In the transparent packaging bag having UV-screening properties, which keeps three sides of a superimposed pile-up film sealed, and the opening sealed after contents are charged from the opening, the light transmittance of the pile-up film at the wavelength of 310 nm is ≤1%, and the pile-up film is used which includes at least a substrate film, a barrier film layer adhered to the substrate film by an extrusion laminate system using a polyolefin resin and a sealant film layer adhered to the barrier film layer.
