First, a sheet S1 to which a biodegradable plastic film whose adhesive layer is protected by a release paper 30 is adhered. Then, a circular slit arranged in 2 columns × 10 rows is formed on the sheet S1 to remove a portion of the biodegradable plastic film other than the circular portion. 30 is placed on the electrode plate P (FIG. 6).
[0037]
In addition, the hanging string 32 is placed so as to pass through the center of the circle on half of the circles arranged in 2 columns × 10 rows left on the sheet S1. At this time, the strap 32 is laid over two circular portions belonging to the same row (FIG. 7).
[0038]
Further, a biodegradable plastic sheet S2 having the same planar shape as the biodegradable plastic film and being thicker than the plastic film is prepared. Then, circular partial cuts arranged in the same 2 columns × 10 rows as described above are made on the sheet S2 (FIG. 8).
[0039]
Next, the sheet S2 is placed on the sheet S1 in such a manner that the respective circles coincide with each other.
[0040]
Then, the electrode E is applied to the center of the circular portions of the sheets S1 and S2, and a high-frequency voltage is applied between the electrodes E and the sheets to bond them. The electrode E is efficient when applied to all the circular parts at once (FIG. 9). At the same time, a circular fold may be formed slightly inside the circular portion of the sheet S2, and the outer edge portion of the circular portion may be slightly curved upward.
[0041]
Finally, unnecessary portions other than the circular portion of the sheet S2 are removed. Since a circular cut is made in advance, it can be easily removed according to the cut (FIG. 10).
[0042]
In this way, each circular portion of the sheet S1 serves as a sticking base material, and each circular portion of the sheet S2 serves as a hooking plate, and the sticking base material and the hooking plate are attached to each other at the center. Also, of the plurality of circular portions of each sheet, the hanging string is attached together at the central portion with respect to a half circular portion, thereby forming a string-hung tool with a string. In addition, a strap that has not been passed over becomes a strapless strap hook, and a pair of strap straps composed of one strap strap and a strapless strap hook constitute a strap strap for closing the lid. . The lace 32, which is connected to each of the two circular portions in the same row, is cut between the two circular portions. In this example, the number of rows is 2 columns × 10 rows, but the number of rows can be arbitrary. As for the rows, it is efficient to manufacture by hanging one strap in common as two rows.
[0043]
