The relationship between ‘handle’ and the bending properties of paper and paper-board is investigated statistically. The handle of Paperboard was recognised to be explained by bending stiffness. In contrast, the handle of paper is complicated by bending stiffness alone. The highest correlation coefficient is obtained for paper by applying the formula Sm²/d where Sm is the maximum bending moment at the curvature of 2.5cm⁻¹ and d is the thickness of the paper.
A simple method of observing the liveliness of paper is also proposed.
