How Much Weight Can a Single Wall Cardboard Box Hold?
Single wall box weight limits: what they can hold and when to upgrade to double wall.
Weight limits by grade
Quick answer
Standard single wall boxes hold 10-15kg for most sizes. The actual limit depends on board grade (flute type and liner weight), box dimensions (larger = lower per-area strength), and stacking (bottom boxes bear the weight of everything above). For items over 15kg, consider double wall. For stacking 3+ boxes high, verify compression strength. Always test with your actual products and stacking scenario.
Factors affecting strength
Higher-grade board holds more weight.
Larger panels flex more than smaller panels.
Bottom box bears the weight of all boxes above it.
Damp boxes lose 30-50% of their strength.
