Abstract

In this study, in order to solve the problem with the folding crack of coated paper, effects of the types of fillers used in the manufacture of base paper on the fold crack of the coated paper were evaluated. GCC and GCC-MFC composite fillers were used as fillers for the manufacture of handsheet paper. In order to investigate the effect of MFC addition as a GCC-MFC composite filler, 3 levels of MFC(2%, 3%, and 4%) were applied. It was found that as the ash content increased, the strength of handsheet paper with GCC and GCC-MFC composite fillers was decreased significantly. The coated paper with GCC-MFC composites as fillers showed the best results in both strength properties and fold crack resistance. Therefore, it was confirmed that replacing GCC with GCC-MFC composites could be used as important means to solve the fold crack problem of coated paper.
