Description

According to the present invention, it is easy to put in and take out sheets such as a plurality of documents and slips, and even if the number of sheets is large, it can be accommodated without difficulty, and writing with a pencil or the like and printing with a printer are possible. Sheets that can contribute to the reduction of waste Paper files.

A synthetic resin file, which is widely used to store multiple sheets of documents together, is a table formed by folding one side edge of a flexible synthetic resin base material into valleys. The sheet and the back sheet are overlapped, and the lower edge of the sheet is heat-sealed and bonded to form a storage portion inside, and most of them are large enough to accommodate A4 size sheets. There is.

Most of the conventional resin files are molded with a transparent or translucent synthetic resin material so that the stored sheets can be visually confirmed from the front side, and are manufactured in consideration of the ease of molding. However, the conventional resin file has the following drawbacks.

First, since the resin file has a structure in which the lower edge is heat-welded by folding it in half, the welded part of the lower edge begins to peel off when the number of stored files is large, and this peeling gradually expands with use. However, it has the disadvantage that it eventually becomes unusable as a file.
Secondly, since the file is molded from a synthetic resin material, a felt-tip pen is used because it is not possible to write necessary information with a pencil, ballpoint pen, or fountain pen, but there is a drawback that it cannot be modified or erased. For this reason, it is troublesome to put up a paper sticker and write. There is also the problem that shredders cannot shred.
Thirdly, when it is disposed of, it is disposed of as plastic waste, but there is a problem that it is against the conservation of the global environment of reducing plastic waste.

Therefore, the applicant can easily put in and take out multiple sheets of documents, slips, etc., can easily accommodate a large number of sheets, is lightweight, and has excellent portability. It is easy to use because it can be recorded with a fountain pen, ballpoint pen, printer, etc. and multicolor printing, it can be shredded with a shredder, it can be used for remanufacturing resources, and it also contributes to the reduction of plastic waste. Therefore, we proposed a sheet paper file that is friendly to the global environment (Patent Document 1).
