During warehouse stacking or stacked transportation, the corrugated boxes on the bottom layer of the pallet experience significant amount of vertical compression stresses. Palletization factors such as pallet gaps, overhang, or interlocking have a major effect on the strength of the corrugated boxes and are already built into the commonly used safety factors. However, the effect of pallet stiffness on the compression strength of boxes is lesser known and not accounted for.
