How Much Weight Can a Double Wall Cardboard Box Hold?
Double wall weight limits: how much they hold and when to use them.
Weight limits
Quick answer
Standard BC double wall holds 20-30kg. AB double wall holds 25-40kg. Actual limits depend on box dimensions (larger panels flex more), liner paper weight (heavier = stronger), and stacking requirements (bottom boxes bear everything above). Moisture reduces strength by 30-50%. Always test with your actual products and stacking scenario. For items over 40kg, consider triple wall or timber crating.
Factors affecting strength
Smaller boxes hold more relative to their size.
The liner specification matters as much as the flute.
Keep boxes dry for full performance.
Flutes: flute guide or structure.
Stacking performance
Double wall boxes stack 5-8 high with standard loads in dry conditions. Edge-aligned stacking maximises strength. Always test stacking with packed boxes for 24 hours before confirming your stacking plan.
