Furthermore, the bottom seal bar 14 is pressed perpendicularly to the vertical seal part 12 from the lowest end thereof to form the bottom seal part 11. Next, the bag is manufactured by cutting the bag in the middle of this vertical seal part 12, cutting off the unnecessary part 18 at the bottom of the bottom seal part, and cutting the upper part parallel to the bottom seal part.

のである。 In addition, when the trunk film and the pocket forming film were constructed separately, the folded part of the trunk part made by folding the strip base film in half was cut with a cutter, but the bag was cut with the folded part facing downward. Once formed, it is not necessarily necessary to cut the fold line.

る。<Effects of the Invention> In the present invention, a vertical seal portion is formed by pressing a seal bar obliquely to the flow direction of the strip film in advance, and a bottom seal portion is provided at right angles to the vertical seal portion. Therefore, the opening of the pocket is not parallel to the bottom seal, but is inclined. Therefore, once the initial settings such as the angle of the seal bar to be pressed are made, the vertical seal part and the bottom seal part are set by pressing the seal bar, and then the middle part of the vertical seal part, the bottom part of the bottom seal part, and the bottom part of the vertical seal part are set. By repeating the extremely simple process of cutting the upper part, a bag having a pocket with an slanted opening can be manufactured, making mass production extremely easy.
