Since the package of the strip-shaped photosensitive material is unsealed by the above-described method, the end portion of the strip-shaped photosensitive material is pulled out from the port and is pulled out to the outside. The part that was removed was unusable due to fog. Therefore, in order to reduce the portion that cannot be used, care is taken to open the outer peripheral packaging material so that it can be stopped immediately after the end of the strip-shaped photosensitive material comes out from the port of the magazine.

However, a person who is accustomed to the opening operation can know the length of the outer peripheral packaging material and can open the waste material in a short time without waste, but a person who is not accustomed to the opening operation takes time. Therefore, it was necessary to carefully pull out the outer peripheral packaging material by hanging it over, and it took a long time to open the packaging material. In addition, such a light-room loadable photosensitive material has a selling point that even a person who does not have special skill (setting of photosensitive material in a dark room) can work, so that anyone can easily open it. It was desired to be able to work.

The present invention solves the above problems and minimizes the fog area of the end of the strip-shaped photosensitive material due to overdrawing of the outer packaging material, even for those who are not familiar with the opening operation. Moreover, it is an object of the present invention to provide a band-shaped photosensitive material package which can be opened in an extremely short time.
