In order to achieve the above-mentioned object, the present invention folds two long films having a heat-sealing property with a predetermined interval and with a predetermined width, and heat-seals the folded-back portion. A pair of strip-shaped folded portions are formed, and two films thus formed are polymerized in a state where the folded portions are aligned with each other, and when both films are melt-cut into a trapezoidal shape, both ends are respectively separated from the folded portions. Assuming a lower bottom located outside and matching one side edge of the long film, and an upper bottom parallel to this lower base and having both ends serving as folded portions, the upper base, the upper A fusion seal is formed between one end of the bottom and one end of the bottom bottom, and between the other end of the top bottom and the other end of the bottom bottom to form the bottom bottom in the opening,
The sandwiched corners of the stored sandwich are positioned at both folded portions, and the folded portion has a width of 20 mm or less.

Then, using the two films 1 and 1 formed as described above, the portions 4 and 4 located between the folded portions 2 and 2 are polymerized so that the portions 4 and 4 are located outside, and
In this superposed state, as shown by the chain line in FIG. 3, the fusing seal 5 has a trapezoidal shape with the upper bottom between the two folded portions 2.
To do. "As shown by the chain line in FIG. 3, both ends are located outside the respective folded-back portions 2 and 2, and
It is assumed that there is a lower bottom that matches one side edge of the long film and an upper bottom that is parallel to the lower bottom and has both ends serving as the folded portions 2 and 2.

つぎに、前記上底、上底の一端と下底の一端との間、
および上底の他端と下底の他端との間を溶断シール5し
