Friction coefficient of cardboard packing samples

High friction coefficient on paper cardboard surface tends to resist the sliding motion in piled box units. Nevertheless, high friction coefficient can potentially damage prematurely the contact surfaces of cardboard packaging boxes. There is still a little knowledge on the friction coefficient behavior of cardboard materials. On the other hand, the concept of Circular Economy (CE) proposes the reuse of resources to extend their service life and maintain their flow through value networks. In the case of cardboard boxes, it is important to preserve their high friction coefficient and minimal wear for reuse. This work aims to identify the static and kinetic coefficients of friction between paper cardboard packing sections on some surfaces by using the inclined plane and the two masses system. The results show how after completing some sliding distance, the friction coefficient tends to scatter the values depending closely on the sliding counter-face roughness. For any industry looking at implementing CE in their operations by the reuse of packaging boxes and to extend their life and save financial and environmental resources, friction values could be an important parameter of quality to decide whether or not the packaging is suitable for reuse.
