PROBLEM TO BE SOLVED: To provide a storage bag which can inform a user of the timing of replacement by making a proper indication when a texture is deteriorated mainly by ultraviolet rays. SOLUTION: The storage bag for grains or the like consists of a bag body including at least a peripheral wall, a bottom of the peripheral wall, and a suspending belt. The bag body is equipped with an indication part consisting of a print part including a dye or pigment highly resistant to weather such as the ultraviolet rays and a shield to be overlaid on the print part and including a dye or pigment less weather-resistant than the former dye or pigment. Thus the user can recognize the deterioration of the bag due to external conditions such as the ultraviolet rays by an indication indicated on the print part. A plurality of the indications are provided longitudinally on the bag body or circumferentially on the bag body. The indication consists of the print part printed on a tape having an adhesive part on the rear and the shield provided over the print part. COPYRIGHT: (C)2005,JPO&NCIPI
