Cardboard Boxes - FAQ

Find answers to common question about double walled cardboard boxes

Double-walled cardboard boxes are made from two layers of corrugated fluting sandwiched between liner boards. This construction provides extra strength, durability, and load protection compared to single-walled boxes.

They are ideal for:

  • Heavy or bulky items
  • Fragile goods requiring extra protection
  • Palletised shipments
  • Long-distance or export shipping
  • Stacking goods in warehouses or storage
  • Double-walled boxes: Two fluted layers, higher strength, better stacking and crush resistance
  • Single-walled boxes: One fluted layer, lighter, suitable for lighter products

Double-walled boxes offer greater protection and durability.

Common flute combinations include:

  • BC flute – very strong, excellent stacking strength
  • EB flute – smoother finish with good strength
  • AC flute – heavy-duty industrial applications
