Bearing Capacity of Board Box and Grain Direction

In this work 6 boards of small (250 g/m2), medium (350 g/m2) and higher (450 g/m2) grammage and different qualities were investigated by Taber method (ISO 2493). Small and medium boxes were made from all investigated boards with grain direction parallel and perpendicular with the hight of the box. Bearing capacity of all boxes was performed by BCT method. From the obtained results of BCT tests it can be concluded that the box strengths are, almost, the same in both directions A (MD) and B (CD).
