What Are Double Wall Cardboard Boxes and Why Are They Stronger?
Everything you need to know about double wall boxes and their superior strength.
What are double wall boxes?
Quick answer
Double wall boxes have two corrugated fluting layers instead of one, providing roughly twice the strength of single wall. They hold items up to 25-40kg, stack 5-8 high, and protect fragile heavy goods during shipping. Use them for items over 15kg, high stacking requirements, export shipments, and high-value fragile goods. They cost 30-50% more than single wall but the extra protection is essential for heavy-duty applications. 100% recyclable through kerbside collections.
Why are they stronger?
Each layer compresses independently.
More material between contents and outside world.
Connecting the flutes adds more than the sum of parts.
