Problems solved by technology

[0003] At present, a large number of folders sold in the market are plastic case folders. When they are used, especially when they are stacked on a plane, the panels are soft and weak, without skinny feeling, and cannot play a supporting role.

Moreover, the outer peripheral end face of the existing folder cover is easily worn during use, which not only affects the external appearance of the folder, but also affects the service life of the folder. Although some paper folders have protective measures for the cover, most of them Using the way of wrapping, not only the production efficiency is low, but also the cost is high

On the other hand, when the existing file folder is made, its buckle device is fixed on the inner side of the file folder cover. This integrated fixing method forms a volume with a fixed size after the file folder is made, regardless of whether there is a file in it. Documents must occupy a certain amount of space. In the storage and transportation of folders, they occupy a large volume, resulting in waste of space and increasing storage and transportation costs.
