る。By providing the reinforcing ribs provided on the front film and the reinforcing ribs provided on the back film alternately, the reinforcing ribs 28 and 29 provided on the front film 5 and the back film 6 are provided as shown in FIG. Since the reinforcing ribs are present in a wider portion of the flow path 3 than those provided so that the reinforcing ribs 30 and 31 provided on the respective portions coincide with each other, the bending of the protruding pouring portion 2 at the time of pouring is performed. Can be further prevented. Further, since the reinforcing ribs are provided with the folds formed in the synthetic resin film, the reinforcing ribs can be hardly bent. In addition, in order to pour out the content liquid from the liquid packaging bag of the present invention, the location of the line AA is cut with scissors or the like to expose the flow path, and then the packaging bag body is pressed. However, at this time, the mountain-shaped concave portion of the reinforcing rib serves as a flow start path of the liquid, so that the flow path is smoothly expanded, so that the pouring operation can be favorably performed.
