There is known a label having a configuration in which Braille is formed by printing on a substrate, a label having a configuration in which Braille is formed by printing the Braille on a base material using a foaming ink, and then foaming.

However, in the case of a label in which Braille is formed by embossing using an intaglio plate for Braille and a relief plate for Braille, it is necessary to produce the intaglio plate for Braille and the relief plate for Braille, and the embossing process is required, which complicates the process. There is a disadvantage that it is difficult to increase the height of Braille in a normal printing method and it is difficult to sense Braille by tactile sense with a label formed with Braille by printing using transparent three-dimensional ink, Labels in which Braille is formed by printing Braille using a foamed ink and then foaming the Braille have the disadvantage that a foaming process is required and that a substrate having excellent heat resistance must be used as a substrate.

Further, as described in Japanese Patent Application Laid-Open No. Hei 10-114310, a preservative hermetically sealed package is hermetically packaged with another packaging material together with the packaged object body, and then a laser beam is irradiated from the outside. The preservative function that perforates the preservative-sealed package only by forming a hole with a rim-shaped protuberance around the perforated preservative-sealed package so that the protuberance also serves as Braille. There is known a packaging processing method that works effectively. However, in this method, the preservative-sealed package is hermetically packaged with another packaging material together with the packaged object body,
A laser is irradiated from the outside of another packaging material to perforate only the packaging material of the preservative-sealed package, and the storage position of the preservative-sealed package in the package in which the packaged object body is packaged is determined. Since it is not constant, there is a disadvantage that it is difficult to collect laser light on the surface of the packaging material of the preservative-sealed package to form fine Braille. In addition, this method is a method of manufacturing a preservative-sealed package with Braille, and is not a method of manufacturing a label with Braille display.
