Extraction bag and packaging material sheet
An extraction bag is disclosed that has a body that can be squeezed using hanging threads. A portion of a sheet body is folded back, and point seals are provided in the folded-back area. Two hanging threads are attached with the point seals as supporting points. Then, when the hanging threads are pulled in opposite directions, the direction of the one hanging thread is guided during pulling by the point seals and the end of an edge seal as supporting points, and the direction of the other hanging thread of a tag-attached hanging thread is guided during pulling by the point seals and the end of an edge seal as supporting points. By this means, the point seals are first pulled towards one another and then the base seals of the threads are also pulled towards one another, thereby squeezing the bag body from three dimensional directions.
