The Effect of Fiber Constitution and Beating Process on Surface Strength of Packing Paper
This article studied on these factors which influences the surface strength of packing paper. Through a series of tests, a model has been found. This model could guide the adjustment about fiber composition and beating process. And then a pilot scale test about this model has been carried out in Henan. The conclusion indicated that surface strength, printability and other strength indexes have been improved by adjustment of fiber composition and beating process scientifically. The ratio of softwood pulp has been reduced from 28% to 23%~25%. And the surface strength has been increased from 0.8~1.2m/s to 1.5~1.8m/s. Furthermore, when the ratio of softwood pulp is 23% and chemical-mechancial pulp is 7%, the packing paper still has a good printability.
