Description

  The present invention relates to an information hiding sheet suitable for protecting personal information and the like and a method for manufacturing the same.

Due to the recent increase in awareness of personal information protection, postcards with concealment labels that can be re-removed and re-applied have been used (for example, Patent Document 1), but many of them can be easily re-removed and re-applied. There were many things that it was difficult to grasp the history.
Therefore, by providing a strong adhesive part on the long side of the concealment label, it can not be opened easily, and it can be opened with a micro-sewing machine, or the paper can be broken at the time of opening, and a postcard with an information concealment label can remain. Etc. are also used.

However, such a postcard with an information hiding label often uses a double-sided tape for the strong adhesive portion, which may increase the cost.
In addition, even if the strong adhesive part is formed by application of an adhesive, the separation layer of the separate paper is often coated with an off-line gravure printing method before and after the pattern printing in offset printing. The processing of the shape was difficult in manufacturing.
For this reason, the strong adhesion part is only on the long side end side that can be manufactured by stripe processing, and there is a possibility that the concealment label and the postcard body are inflated and the inside can be viewed from the short side. It was.
