Investigation of the Relation Strength/Grain Direction of the Board Folding Box

The aim o this work was to investigate bearing capacity of small board boxes produced from the boards of 250 g/m2 of different qualities. Somewhat lighter boards, than usually, were chosen with the intention that the strength of the material itself participates as little as possible in the obtained results. Small boxes were made from investigated boards ; 10 boxes of each board 5 with grain direction parallel with the height of the box and 5 with grain direction perpendicular to the height of the box because such boxes has never been examined before. The testing of box strength was performed by the BCT method and Acquati (Milan) tester was used. Chemical, basic and mechanical properties of boards were carried out too in order to find out if there is any correlation between box strength and some properties of boards.
