In the inside of the open edge portion 3a, a flexible cord body 4 half-folded in the length direction is housed, and further, the cord body 4 has both end portions 4b, 4c at left and right sealing portions b, It is adhesively fixed to the inner surfaces of the front and back wrapping material 3 in a state of being sandwiched by c.

In this packaging bag 1 with a handle, two packing materials 3 are superposed in a state in which a cord body 4 is inserted in a lateral direction, and an upper seal portion a is formed at a position slightly below the cord body 4. And the left and right seal portions b and c are adhered so that both ends 4b and 4c of the cord body 4 are sandwiched and adhered. Since the packaging bag 1 is manufactured in this manner, the string body 4 can be attached by an in-line process using a conventional bag manufacturing machine for manufacturing a packaging bag.

The packaging bag 1 is supplied in the state shown in FIG. 1, and after filling the contents from the lower opening in FIG. Adhesive and sold. Then, when carrying, the cord body 4 is pulled out from the open edge portion 3a and used as a handle. Further, since the cord body 4 has flexibility, it can be easily housed in the release edge portion 3a by pulling both ends 4b and 4c of the cord body 4 together with the bag body 2 outward.

As the above-mentioned packaging material 3, various kinds of plastic film simple substance, a plastic film laminated body, or a laminated body of these and paper similar to the conventional packaging material forming a packaging bag can be used. In addition, it is necessary that the bonding surface has a heat-sealing property when making a bag. Also,
The packaging material 3 may optionally be provided with a printing layer or a vapor deposition layer. On the other hand, as the string 4, various plastic films, non-woven fabrics, cloths, strings and the like can be used alone or a laminated body thereof. Further, the shape of the cord body 4 may be a simple band shape as shown in FIG. 3 or a cylindrical shape as shown in FIG.
At the time of implementation, an appropriate one may be selected from these shapes in consideration of the material of the cord 4 and the weight of the contents. The wrapping material 3 and the cord body 4 are bonded to each other by heat sealing when the cord body 4 can be heat-sealed, and when not, heat the polyethylene cord or the like on both sides of the cord body 4. Heat sealing is performed by laminating a fusible resin, or bonding is performed with an adhesive or the like.

In the embodiment shown in FIG. 5, the length of the cord body 4 is shortened, and both ends 4b and 4c thereof are bonded and fixed inside the left and right seal portions b and c of the bag body 2. In this way, by changing the bonding position of the packaging material 3 and the cord body 4, the length of the cord body 4 serving as a handle can be adjusted.

In the embodiment shown in FIG. 6, both ends 4b and 4c of the cord body 4 are bonded and fixed in a region wider than the left and right seal portions b and c. By increasing the adhesion area in this way, the attachment strength of the cord 4 can be increased.

In the embodiment shown in FIG. 7, both ends 4b and 4c of the cord body 4 are bonded by the left and right seal portions b and c, and
Adhesion is reinforced by the band portions 4d and 4e that extend obliquely upward from the intersection of the upper seal portion a and the left and right seal portions b and c to reinforce the attachment strength. By thus reinforcing the slanted strip portions 4d and 4e, the load acts evenly on the strip portions 4d and 4e when the heavy packaging bag 1 is hung, so that the cord 4 is attached. It is possible to prevent the packaging bag 1 from tearing from the portion.
