<P>PROBLEM TO BE SOLVED: To provide an inflation molding bag allowing overall thickness to be reduced by forming uneven vertical reinforcing portions on both side parts of the bag to hold the bag well, and allowing printing or the like to be easily performed by forming a flat and thin part, and to provide a method of manufacturing the same. <P>SOLUTION: In this inflation molding bag 10, an inflation film 11 is formed into a cylindrical shape, and formed into a bag-like shape by sealing its bottom part at a thermally-welded portion 12. On both side parts of the inflation molding bag 10, vertical reinforcing portions 15 formed with a plurality of vertical reinforcements 14 by projecting bars are provided, and a flat thin part 17 formed thin relative to thickness of the vertical reinforcing portions 15 is formed between the vertical reinforcing portions 15. On the surface of the thin part 17, a print portion 18 to which printing for displaying a stored object is provided is formed. The width S of the vertical reinforcing portion 15 is set so that the chuck of a packaging machine can hold the bag in storing the stored object in the bag. <P>COPYRIGHT: (C)2012,JPO&INPIT |
