Single-wall vs double-wall boxes
The difference is the corrugated construction — one layer of fluting or two — and it decides how much weight and handling the box takes.
Quick answer
Use single-wall for light-to-medium items posted by courier; step up to double-wall for heavy, dense or fragile goods and anything going on a pallet.
When to request a quote
Ask for a quote if you're not sure of the grade — tell us the weight and contents and we'll recommend single or double wall.
What each option is best for
Single-wall boxes
One layer of fluting — the everyday grade.
Best for: Light to medium ecommerce parcels
- Lighter and cheaper per box
- Fine for most sub-10kg parcels
- Widely recyclable kerbside
- Less crush resistance when stacked
Double-wall boxes
Two layers of fluting — heavy-duty.
Best for: Heavy, dense or fragile goods
- Much higher crush and stack resistance
- Better for freight and pallets
- Protects heavy or fragile contents
- Heavier and costlier per box
