Study on Making Low Density Printing Paper with Aspen BECMP as the Main Pulp

Article Preview

Abstract:

Low density printing paper was widely used in printing best-seller at present. Besides of high bulk, good stiffness, soft color, it also had some advantages, such as reducing user’s load, protecting eyes, extending the storage time etc. Quality index of domestic low density printing paper was lower than foreign index. The gap mainly expressed on tensile index specially. This study used Aspen BECMP as main pulp, as a result of its higher strength, lower cost and other advantages comparing with PRC-APMP. Here we discussed three pulps ratio to make low density printing paper. The results of experiment indicated that using Aspen BECMP was able to make low density printing paper by adding certain amount chemistry pulp. Moreover, the best bulk value can up to 2.45cm3/g, and the tensile index was 36.08Nm/g.
