Then, the processing is performed in the following order. (A) Put the polyethylene tube 15 in the frame 1 and bend the upper end of the polyethylene tube 15 outward to form a bent flange 15a on the upper surface of the circular receiving frame 2. Then, the flat film 16 for bottom is placed on the upper surface thereof. (B) The circular crimping frame 7 is rotated to overlap the circular receiving frame 2 side. (C) The switch 14 is turned on to energize the circular band heating wire 4. (D) The unnecessary bent flange portion 15a is removed by melting with the circular band-shaped heating wire 4. (E) Turn off the switch 14 to stop the energization of the circular heating wire 4. (F) A cooling period of about 10 to 20 seconds is set in order to secure the welded seal surface. (G) A circular sealing surface is formed to obtain a product. (H) Open the circular crimping frame 7 and take out the product.
