Pallet stacking in long-haul ocean containers subjects bottom cartons to immense static and dynamic compression loads.
Calculating Required BCT
Using the McKee formula, engineers predict compression failure based on board caliper, perimeter, and ECT values.
Humidity Safety Factors
Relative humidity above 80% degrades fiber rigidity by up to 50%; calculating a 4.5x safety multiplier prevents carton collapse.
