Abstract
This work aims to clarify that the effect of bending speed and repeated reverse crease on the bending characteristics of white-coated paperboard. In order to reveal the fundamental characteristics, the bending moment resistance is measured. A 232 g/m2 white-coated paperboard was scored by a round-edge blade and a grooved counter plate. The bending test of the scored specimens by the CST-J1 was carried out under the specified parameters for investigating the bending speed chosen as six kinds and the retained time duration of 0,10s at the tracking angle. Regarding the reverse crease, the relationship between the repeated number of bending and the gradient of bending moment was investigated.
