A light-shielding packaging for a roll of continuous photosensitive web wound on a core having on its each end a light-shielding flange disc has at its leading end a light-shielding leader sheet. The leader sheet is composed of a longitudinal light-shielding base sheet and two heat-shrinkable light-shielding strips, in which each of the light-shielding strips is tearable predominantly in its longitudinal direction and is fixed onto a surface of each side of the light-shielding base sheet under the condition that the light-shielding strip is aligned in parallel with the side of the longitudinal base sheet to project its portion from the side of the base sheet.
