Abstract

The strength of linerboards produced in summer was weaker than that in winter. In this study, efforts were made to increase the consistency of OCC pulp to improve the strength of linerboards produced in the summer. The pulping temperatures of summer and winter were set at 52℃ and 19℃, respectively. The pulping consistency was set 5% at 19℃ in winter and 5, 6, 6.5 and 7% at 52℃ in summer. As a result, it has been found that the strength of the linerboard can be improved by increasing the pulping consistency. The strength of the linerboard with a pulping consistency of 6% and a pulping temperature of 52℃ is similar to that of 5% and 19℃. The linerboard strength increased by more than 20% when the consistency increased to 6.5 and 7%. Therefore, an increase in pulp consistency is considered to be one of the solutions to improve the strength of linerboards in summer.
