Sheets that can contribute to the reduction of waste Paper files.

Files for synthetic resin sheets, which are widely used to store multiple sheets of documents together, are made by folding one flexible synthetic resin base material into valleys and folding the front and back sheets. The sheets are overlapped, and the lower edge portions thereof are heat-fused and bonded to form a storage portion inside, and most of them are sized to accommodate A4 size sheets.

Most of the conventional files for sheets are made of a transparent or translucent synthetic resin material so that the stored sheets can be visually recognized from the front side and easy to mold.

I couldn't find it.

(1) Since the above-mentioned conventional synthetic resin file has a structure in which the lower edge is heat-welded by folding it in half, the welded portion of the lower edge begins to peel off when the number of stored sheets is large, and this peeling is used. There is a drawback that it gradually expands with it and eventually becomes unusable as a file.
(2) 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.
(3) Furthermore, even if 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.

The present invention has been made in view of the above-mentioned drawbacks and unsolved problems of the prior art, and 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 is reasonable. It can be accommodated and is lightweight, so it is highly portable. It is easy to use because it can be recorded with pencils, fountain pens, ballpoint pens, printers, etc. and multicolor printing, and it can be shredded with a shredder. The purpose is to provide sheets made of paper that are friendly to the global environment because they can be used for remanufacturing resources and contribute to the reduction of plastic waste.
