Description

Technical Field

[0001] The utility model relates to the technical field of envelopes, in particular to a novel document binding envelope. Background Art

[0002] Document binding envelopes are widely used due to their advantages such as easy operation and beautiful binding effects. Their working principle is to place the documents to be bound neatly in the envelope, use a heating device to melt the hot melt glue at the edge of the envelope, and after the hot melt glue cools and solidifies, the documents can be fixed. This binding method can effectively protect the documents and prevent them from being scattered and damaged. At the same time, the bound documents have a neat appearance and are easy to store and consult. However, due to the lack of a file holding device in existing document binding envelopes, when the neatly arranged documents are transferred to the heating device, the documents are easily shifted and scattered due to factors such as shaking and collision. Once the documents become uneven during the transfer process, the final bound documents will have uneven edges, which greatly affects the binding quality. Utility Model Content
