Unit 13 - Paper and Board

13.1.5.2.3.Strength of the corrugated fibreboard box

• Ability to withstand rough handling resistant to impact, resistance to puncture and bending which depends on puncture resistance and bending stiffness of the board respectively.

• Ability to withstand compressive load in stalking.
• Depends on the perimeters (perimeter) 1/3
• Increases with flute height.
• Increases directly with strength (ring stiffness) of the paper.
• Depends on the busting strength of the board.
• Depends on the relative humidity of the atmosphere.
• Depends on the fabrication defects of the board and the box.
