摘要

The safety paperboard for packaging banknotes and other products, comprises a kraft paper sheet with an external cover and an interior layer, and a corrugated board intermediate layer (31). The paper sheet comprises security particles distributed in the sheet during a manufacture of the particles according to a given distribution, which is combined according to a nature of the particles. The distributed particles are appears on an external surface of the sheet. The security particles are elements of group comprise fibers and/or confetti, luminescent and colored powder. The safety paperboard for packaging banknotes and other products, comprises a kraft paper sheet with an external cover and an interior layer, and a corrugated board intermediate layer (31). The paper sheet comprises security particles distributed in the sheet during a manufacture of the particles according to a given distribution, which is combined according to a nature of the particles. The distributed particles are appears on an external surface of the sheet. The security particles are elements of group comprise fibers and/or confetti, luminescent and colored powder in which the particle is distributed in the sheet according to predetermined pattern. A predetermined proportion of particles and several types of security particles are mixed with different physicochemical characteristics to constitute a coding. A density of given distribution of the security particles are useful to carry out the coding. An independent claim is included for a process of manufacturing a paperboard plate.
