Since the ratio between the width dimension of the hook 40 and the distance between the adhesive portions 61 and 62 in the longitudinal direction of the handle 20 is in the above-mentioned range, it is formed between the base portion and the finger hook portion. A finger can be reliably inserted into a space communicating with the outside in the height direction, and the finger hook portion is not easily bent when the handle is lifted. Therefore, the packaging bag in which the packaged body is accommodated can be stably carried.

  In the first embodiment, the first finger hook 30 is provided on one surface 20B of the base 20A, and the second finger hook 40 is provided on the other surface 20C of the base 20A. Can be provided. Therefore, as shown in FIGS. 2 to 8, the finger P can be inserted from any of the surfaces 20 </ b> B and 20 </ b> C of the handle 20. Moreover, even if the fingers P are inserted from either of the surfaces 20B and 20C of the handle 20, the packaging bag can be carried in a stable state while reducing the burden on the fingers P.

  Further, in the first embodiment, by providing finger hook portions on both surfaces of the base 20 </ b> A, the handle 20 is tilted to either the first finger hook 30 or the second finger hook 40 with respect to the bag body 10. Even if it is, the finger hook part (either the first finger hook 30 or the second finger hook 40) of the handle 20 can be recognized. Even if either the first finger hook 30 or the second finger hook 40 is damaged, the finger P can be hung on either the remaining second finger hook 40 or the first finger hook 30. Therefore, the packaging bag 100 is highly versatile as a packaging bag.

  In addition, the dimension of each thickness (thickness of the Z direction of FIGS. 2-5) of the 1st finger hook 30 and the 2nd finger hook 40 is arbitrary. For example, each thickness of the 1st finger hook 30 and the 2nd finger hook 40 can be 20 micrometers or more, Preferably they are 30 micrometers-150 micrometers, More preferably, they are 40 micrometers-90 micrometers. By making the first finger hook 30 and the second finger hook 40 have such thickness dimensions, the first finger hook 30 and the second finger hook 40 can be prevented from extending or breaking. Further, the first finger hook 30 and the second finger hook 40 can be securely bonded to the base 20A by heat welding or the like.

  In the first embodiment, on the side where the first finger hook 30 of the handle 20 is provided, the lower end 21 of the handle 20 of one adhesive portion 51 of the pair of adhesive portions 51, 52 of the first adhesive portion 50.
