The current invention involves a new process for fixing non- cellulosic fillers onto tissue paper between 14 gsm and 50 gsm, either for paper produced from a cellulosic furnish of virgin fibers or for paper produced from a cellulosic furnish of recycled fibers derived from recycled papers. The process consists essentially of introducing in a cellulosic fibrous solution a non-cellulosic filler of calcium carbonate (CaC03) or other, then applying, in sequence, two chemical agents, a micro-particle added before the pressure screen and a polymer in the fibrous solution after the pressure screen. The process did not affect the quality of the paper sheet nor the paper making equipment.
