The lightweighting of newsprint is an important measure to protect forest resources and reduce the cost of newspapers. Therefore, lightweighting is the future trend of newsprint. Huatai Group's postdoctoral research station focused on the adjustment of raw material structure and successfully developed a process technology for producing ultra-lightweight newsprint paper using waste paper as the main fiber raw material.
The process technology mainly includes: optimization of the ratio of fiber raw materials, establishment and optimization of the wet retention and assisting filtration system, optimization of reinforcing agents, use of new types of fillers, and supporting technologies. The 40 g/m2 ultra-lightweight newsprint produced using this technology has many advantages such as fine texture, high opacity, good ink absorption, and good printing adaptability.
