Financial password envelope

Abstract

A financial password envelope comprises a self-developing layer, a glazed paper layer, an adhesive layer and a coiling block. The glazed paper layer is located on the inner side of the self-developing layer, the adhesive layer is located between the glazed paper layer and the self-developing layer, and the self-developing layer, the glazed paper layer and the adhesive layer are fixed to the coiling block in a roll mode. The financial password envelope has the advantages that the structure that the glazed paper layer 2 and the self-developing layer 1 are bonded through the adhesive layer 3 is adopted, the glazed paper layer 2 and the self-developing layer 1 are temporally bonded, one-time uncovering can be achieved, bonding cannot be achieved after uncovering, the glazed paper layer 2 is prone to fracture after uncovering while developing of the self-developing layer 1 is not affected, and the surface can wrinkle and become uneven even when the water-based obstruction adhesive is manually applied. Thus, repeated utilizing cannot be achieved after uncovering, and leakage of a password is avoided. One-time machining forming is achieved during production, the phenomenon that an upper piece of paper and a lower piece of paper are different in length is avoided, and the appearance is flat and free of wrinkles. The upper piece of paper and the lower piece of paper exist in the form of coiling blocks, uncovering can be achieved during using, and stealing is not facilitated.

Description

technical field [0001] The invention relates to a measurement tool, in particular to a financial cryptographic seal. Background technique [0002] For a long time, the construction of the combination envelope has been carried out in the traditional way. That is to print the upper layer of carbon-free CB paper and the lower layer of CF paper respectively, and after printing, glue around the binding machine to form an envelope. In the production process of this process, since the upper and lower layers are printed separately, the upper and lower layers are prone to be of different lengths during the printing process, which can easily cause the envelope to be glued or folded during the pasting process. Once the envelope is unglued, the password will be leaked; the upper and lower layers of paper will be folded during pasting, folding and delivery, which will cause printing jams during use. Once a paper jam occurs, the product needs to be scrapped, which not only brings great...

AI Technical Summary

Problems solved by technology

In the production process of this process, since the upper and lower layers are printed separately, the upper and lower layers are likely to be of different lengths during the printing process, which can easily cause the envelope to be glued or folded during the pasting process.

Once the glue of the envelope is opened, the password will be leaked; the upper and lower layers of paper will be folded during pasting, folding and delivery, which will cause printing jams during use.

Once a paper jam occurs, the product needs to be scrapped, which not only brings great hidden dangers to the safety of the product, but also affects the use efficiency and increases the use cost

[0003] In addition, the traditional password seal is made of glue on the edges of the upper and lower layers of paper, and the glue is ordinary water-based glue.

There are often criminals who uncover and steal the password of the middle number segment and then stick it with glue. The stolen password can be reused, and the security and anti-counterfeiting are poor.
