Abstract
Abstract A magazine for a roll of a photosensitive strip material which comprises a core rotatably supporting the roll and a light-shielding container body admitting the core and having an opening for drawing out the photosensitive strip material and light-shielding teremp cloth piece(s) provided at the above opening, and which is characterized in that the wall of the container body is formed by paper board and a multilayer film superposed thereon containing a metal foil layer or a metallized flexible sheet layer being visible from the outside and that the ground fabric structure of the above teremp cloth is knit structure. This magazine is superior in moistureproofness, gas barrier, dustproofness, thermal-shielding, water proofness and antistatic property. Deformation of the opening for drawing out hardly occurs, and leakage of light and moisture do not occur. Even though this magazine is left in the sunlight for a long time, inner temperature of the magazine is not so raised. Quality of the photosensitive strip material packaged by this magazine is kept for a long period irrespective of outside conditions. The magazine of the invention is inexpensive, and its waste treatment is easy.
