In this study, effects of base paper and pick-up weight of sizing agent on the physical properties of impregnated paper were investigated. Bulk and wet strength of base paper were changed, and pick-up weight of sizing agent were controlled by changing solids contents of sizing agent and squeezing pressure after impregnation. It was found that increase of bulk caused increase of strength by high pick-up weight of sizing agent. Especially, folding endurance of impregnated paper had a almost linear relationship with pick-up weight of sizing agent. Wet strength of base paper was related with that of impregnated paper.
