The spouting auxiliary member 20 is made of a plastic elastic body and composed of a bottom wall 21 and lateral walls 22 stood upward from both ends of the bottom wall, and is U-shaped in a front view. The packaging bag can prevent intervals of two-side laminate film 1 from extending so that when forming a spout sealing portion, floating at the spout sealing portion and thinning of the sealing portion can be prevented from occurring and also the spout can be prevented from being clogged. |
