85g Green to Blue Thread Security Paper
Green to blue thread paper is a specific type of security paper that incorporates a security thread as an anti-counterfeiting measure. This thread is usually made from a thin plastic film that has been dyed two different colors, green and blue. When the paper is held flat, the thread appears green. But, when the paper is tilted, the thread appears blue. This color shift is due to the way light interacts with the different layers of the dyed film.
