PROBLEM TO BE SOLVED: To provide a power and grain body storage bag capable of stand up the whole storage bag. SOLUTION: The power and grain body storage bag has a bag body 3 integrating two plastic sheet bodies 2 by fusion-welding them, and corner fusion-welding sections 7 intruded from the outer peripheral end edge 6 of the bag body 3 to the inside are formed on both end corner sections 5 of the bottom side 4 of the bag body 3. A bottom surface wall 1 capable of standing up the whole storage bag in a powder and grain storage state is formed between the right and left corner fusion-welding sections 7. Corners 13 of both end corner sections 5 of the bottom side 4 of the sheet body 2 are cut off by cutting lines 12 in which angleθagainst the bottom side 4 is set up to be 40°≤θ≤50°. A width dimension w of the corner fusion-welding section 7 is set up to be 4 mm≤w≤9 mm. COPYRIGHT: (C)2008,JPO&INPIT
