Next, the manufacturing method of the above-mentioned packaging bag will be described with reference to FIG. 8. First, a long series of sheets 11 for a back body made of a thermoplastic resin is sent in the direction of the arrow shown in the figure. The back body sheet 11 is formed by laminating a resin film having a lower melting temperature on one side of the base sheet as described above, and using a resin film having a lower melting temperature on the upper surface side. Next, the inner-fold sheet 12 made of a thermoplastic resin is folded in half to align both ends in the width direction at the center portion on the upper surface side, intersects the back-sheet 1 1 vertically, and is placed on the back-sheet 1. 1 above. This pair of pleated inner pleats 12 is also formed by stacking a resin film having a lower melting temperature on one side of the base sheet as described above, but a resin film having a lower melting temperature is formed on the outer surface side. The front end of the inner pleating sheet 12 is formed so as not to reach the widthwise end of the back body sheet 1 1. Next, the reinforcing tape 3 8 is placed at a position perpendicularly intersecting with the inner pleating sheet 12 and covering the upper edge of the inner pleating sheet 12.

Description of the invention (7) The substrates 7 and 8 are formed with separate grooves and One side of the continuous strips 1 4 and 1 3 of the pair of raised strips 5 and 6 is, for example, the continuous strips 1 3 of the clip 6 with the raised strips are placed and overlapped on the above-mentioned reinforcing strips 3 8. Then, the continuous belt 13 of the clip chain 6 also intersects the inner pleating sheet 12 perpendicularly, and is positioned so as to cover the upper edge of the inner pleating sheet 12. On the other hand, the continuous belts 14 and 13 of the chain 5 and 6 are also made of a thermoplastic resin. The continuous belt 1 3 and the reinforcing belt 3 8 of the clip 6 are fused to the back body sheet 11 while covering the upper edge of the inner sheet 12. In this fusion, the base sheet of the inner pleated sheet 12 or the back body sheet 11 is fused and laminated at the melting temperature of the resin film having a lower melting temperature. At this time, only the outer surface side of the pleated sheet for inner pleats 12 is fused. The upper part 32 is fused with the continuous belt 13 of the chain 6 and the lower part is fused together. 3 3 is fused with the back body sheet 1 1 (refer to FIG. 8), but the inner surface side of the inner pleated sheet 12 is not fused and maintained in a separated state. Next, the back sheet 12 is cut at a position on the other end in the width direction of the back sheet 11 so that the back sheet 11 is moved by a certain interval. As in the above, the back sheet is also applied to the back sheet. The inner pleating sheet 12 is overlapped with the upper surface of the sheet 11 and the overlapping reinforcing tape 38 and the continuous belt 13 of the chain 6 are placed on the inner pleating sheet 12 and fused together. The inner pleating sheet 12 is cut and the process is repeated. Next, the back body sheet 1 1, the inner pleating sheet 1 2, the reinforcing tape 3 8 and the continuous belt 1 3 of the sandwich 6 are overlapped on top of each other.

Description of the invention (8) A thermoplastic resin with the same width as the back body sheet 1 1 is placed A long series of sheets for frontal body 16. This sheet for frontal body 16 is also on one side of the base sheet as described above A resin film having a lower melting temperature is stacked, and the resin film having a lower melting temperature is placed on the lower surface side. The vicinity of one end in the width direction of the lower surface of the front-face sheet 16 will face the above. The continuous belt 14 of the continuous belt 1 3 of the clip chain 6 is fused and fixed at the other end of the continuous belt 14 of the clip chain 5. In this way, the back body sheet 1 1, the inner pleated sheet 1 2, the reinforcing belt 3 8, and a pair of clipped The continuous belts 1 3, 14 and the front body sheet 16 are overlapped together. Since the clip chains 5 and 6 are closed to each other, they are fused together. This fusion is made of a resin with a lower melting temperature. The melting temperature of the film fuses each of the base sheet 12 or the back sheet. The sheet 11 and the front sheet 16 are each laminated. In the figure, reference numeral 18 indicates the fusion portion. That is, the center position of each inner pleating sheet 12 that is parallel to the pleats at a certain interval is fused in the long axis direction, and the widthwise ends of the front body sheet 16 and the back body sheet 11 are also fused. The lower part of the bag body 10 is also fused with the corresponding place. The lower part of the body 10 may be fused with the upper part of the bag main body 10, that is, the front end of the side parts 3, 4 and 35. That is, the lower or upper part of the bag main body 10 is opened for storing the contents. Even when fused, each of the inner pleats for pleats 12 is fused only on the outer surface side, and the inner surface side is not fused to maintain the separated state. The pleats are then cut in the long axis direction. The center position of the fusion part 1 8 of the sheet 12. At this time, cuts 3 are formed on both sides of the side parts 3 4 and 3 5 6.
