Abzac Canada is a company working in the pulp and paper industry. It specializes in manufacture of cardboard products. The company is currently working on the development of a new generation of cardboard angles called Multifold® used to protect packages during handling. The objectives of this new generation are to reduce the quantity of raw materials used for their manufacture, reduce the carbon footprint, reduce the manufacture cost, and finally, offer better mechanical properties than the cardboard angles currently on the market. The objectives of this particular study project are as follow; to characterize the mechanical behavior under compression and three-point bending of Multifold® angles with different types of papers and different types of polymer adhesives, to benchmark the behavior of Multifold® angles against the current generation of cardboard angles, to study the influence of humidity on the mechanical behavior and to study failure modes under compression and three-point bending for the new angles. To our knowledge, there is no complete standard for mechanical characterisation of laminated cardboard angles. The work carried out up to present has focused on the development of an appropriate methodology for compressive and three-point bending tests of laminated cardboard angles. Preliminary tests were used to fix the various tests parameters such as the length of the specimens, the testing speed as well as support conditions.
