When polyethylene terephthalate is used, it has heat resistance as compared with other synthetic resin films, and therefore, for example, when both pieces 1a and 1b are both made of paper sheets, printers, etc. It may be possible to pass through.

Further, in the above embodiment, the paper sheet is coated with the synthetic resin, but the synthetic resin layer may be formed on the inner surface of the paper sheet by laminating the synthetic resin instead of coating. However, when a paper sheet is coated or laminated with a synthetic resin, the same material as the film sheet is necessary for thermocompression bonding.

Further, instead of coating or laminating the synthetic resin as described above, it is also possible to provide a heat-adhesive adhesive at the sealed position. Further, in the above-described embodiment, the seal portions 4 at the side edge portion and the lower edge portion are formed to have the same width, but it is not a condition that they are formed to have the same width, and the side edge portion and the lower edge portion have the seal portion 4. It is also possible to change the width of 4. Therefore, in the process of manufacturing the file, it is possible to change the widths of the seal portions formed at the central portion in the longitudinal direction, the side edge portions in the longitudinal direction, and the positions at equal intervals in the lateral direction of the long sheet.

When both the pieces 1a and 1b of the file body 1 are made of paper, it is possible to cut out a part of the file body 1 and attach a film to the portion to form a transparent window portion. Is.

Further, in the above embodiment, the printing is performed on the paper sheet side, but it is not a condition that the printing is performed on the paper sheet, and the printing may be performed on the film sheet side. Further, both the paper sheet and the film sheet may be printed.

The means for sealing and is not limited to the thermocompression sealing as in the above embodiment, but may be ultrasonic welding, for example.

Further, in the above embodiment, the file body 1 is composed of the front and back two pieces 1a and 1b, but the file body 1 can be composed of three pieces. The point is that the file body 1 is composed of at least two pieces.

In the case of being composed of three pieces, for example,
As shown in 30, the center piece 1b is made of paper, and the pieces 1a, 1
It is possible that c is made of film.

Further, the printing applied to the file body 1 is not limited to gravure printing, flexographic printing, offset printing and the like. Further, so-called medium ink can be used when performing these printings. The medium ink is applied to a film or the like by surface treatment from the beginning, and is for improving the fixability of the ink further applied thereon.

Further, as for the type of objects to be stored in the file, in addition to various documents such as materials, contracts, quotations, proposals, company information, catalogs, etc., samples other than documents should be stored. It is also possible, and in any case, the type of the stored object does not matter.

[0089]

As described above, according to the present invention, the file body is composed of at least two pieces of front and back separate bodies, and at least one side edge and the lower edge of both the front and back pieces are sealed to a predetermined width. Because it is configured, compared to the conventional file that includes both the half-folded part and the seal part such as ultrasonic waves, it is easier to manufacture, the productivity is significantly improved, and the manufacturing cost of the manufactured file is also significantly higher. There is an effect that it can be reduced.

This will be explained based on the manufacturing method of the present invention. Two long sheets are polymerized and a predetermined position is sealed to form a seal portion, and a side edge portion or a substantial portion of the seal portion is formed. By cutting the central part, a file body in which one side edge and a lower edge are sealed to have a predetermined width, or a file where both side edges and a lower edge are sealed to have a predetermined width. Since the main body is manufactured, it is possible to continuously and automatically manufacture such a two-side seal or three-side seal file, and it is possible to provide a manufacturing method suitable for mass production of files. is there.

In particular, in the manufacturing method of the present invention, when the width of the long sheet is formed to have a size corresponding to two dimensions of the longitudinal direction of the file body, the file production efficiency is doubled. There is an effect.

In any case, in the manufacturing method of the present invention,
Since the step of folding in two as in the conventional case is not necessary, the manufacturing is very easy and the production efficiency is greatly improved.

When one piece of the file body is made of a synthetic resin sheet and the other piece is made of a paper sheet, the contained object can be seen through from the outside through the one piece made of the synthetic resin sheet. At the same time, since characters or the like can be written or printed on another piece made of a paper sheet, it is possible to add various information that cannot be realized by the conventional clear file.

Further, when at least one of the two pieces of the file body is made of a paper sheet, it can be passed through the printer or discharged from the printer, so that both pieces of the file body are printed. As a result, even if both sides of the file body are plain with no printing etc. at the time of sale, the image captured by the purchaser, for example, with a digital camera is printed by the printer connected to the personal computer. As a result, a desired photograph or the like can be printed on both pieces 1a of the file body as described above, so that the purchaser can freely add information.

Even in this case, even though the main body of the file is composed of at least two paper sheets, since there is a seal portion, it is necessary to pass the printer or the like through the portion where the seal portion is formed. By
It does not cause any trouble.
