PROBLEM TO BE SOLVED: To provide a packaging bag with a spout having favorable productivity and improved content spouting performance.SOLUTION: In a packaging bag with a spout, a spout portion having an opening means is arranged at an upper part of a packaging bag formed of a laminated film. At a position on an inner side of the spout formed by opening the spout portion, a spouting auxiliary member is mounted to an inner face side of the laminated film. After opening, a content is spouted from the spout via the spouting auxiliary member. The spouting auxiliary member 20 is formed of a gutter-shaped elastic member having an opening 21 in the longitudinal direction, and includes cuts α formed in a direction intersecting with the longitudinal direction from an outer side of a bottom 22 which is a portion opposing the opening 21. When the spouting auxiliary member 20 is mounted to the inner face of the laminated film, the spouting auxiliary member 20 is deformed due to its elasticity and the cuts α so as to reduce tension and an external force applied to the laminated film and to prevent the generation of damage and wrinkles of the laminated film. |
