Ever since our establishment in the year 2014, we have been engaged in exporting and supplying a quality accredited Ammonia Paper Roll, which is also known as diazo paper roll. This paper roll is used for making blueprints or reproducing architectural documents that can be preserved for a longer period of time. As the surface of this paper is coated with the diazonium salt (sensitive chemical), the printing process takes place when it goes through the ammonia printing machine, where the reaction between ammonia and diazonium salt takes place. The print made from the reaction of these two chemicals results in denser image, faster printing speed and superior shelf life.
