ABSTRACT:
A package of rolled photosensitive mateiral comprising a core, a photosensitive strip material wound around the core, a light-shielding leader connected to the end of the photosensitive strip material to shield the peripheral surface of the photosensitive strip material from light and side light-shielding covers connected to both sides of the light-shielding leader so that the boundary between the side light-shielding covers and the light-shielding leader corresponds to the boundary between the peripheral surface and the side surface of the photosensitive strip material. The core is formed by laminating at least 2 sheets of a base paper being moistureproof. The side light-shielding covers are composed of a composite film having a polyethylene film having light-shielding ability and a uniaxially oriented film or a biaxially oriented film made of polyester, polyethylene polypropylene or nylon with the length of the side light-shielding covers being not less than twice as long as the outer periphery of a roll of the photosensitive strip material.
