PURPOSE:To inexpensively provide a magazine for photosensitive materials which has excellent moistureproofness, maintains the strength and dimensional accuracy of the slot of a body part and has excellent light shielding performance by using a sheet made of a PP resin and assembling the magazine by bending said sheet. CONSTITUTION:The sheet consisting of the PP resin into which an adequate ratio of carbon is incorporated in order to shield light is used as the material of the body part 1 having a square cylindrical shape. Said body part is assembled by bending said sheet to form the body part and subjecting the part to, for example, ultrasonic sealing. Two end caps 4 to seal both ends of the body part 1 is made of a molding of the similar plastic or others in terms of working accuracy. Since the body part 1 is constituted of the PP resin in the above- mentioned manner, the magazine has the excellent moistureproofness and strength and since the resin has a good hinge property (foldability), working is easy and the higher dimensional accuracy is obtainable. |
