Shipping Comparison

Single Wall vs Double Wall Corrugated Boxes

Pick the right flute for the journey ahead.

Direct answer

Single wall corrugated suits most ecommerce and retail products with moderate protection needs; double wall adds a second flute layer for heavy, fragile or long-haul shipments. Double wall costs more and weighs more, so use it only where stacking, drops or weight require it.

FAQ

When do I need double wall boxes?

For heavy items, fragile products, pallet stacking, or long international shipments where single wall might crush or fail transit tests.

Do double wall boxes cost much more?

They cost more per box and add shipping weight, so the total premium can be significant. Use them only where tests show single wall is insufficient.

Can I print on corrugated boxes?

Yes, flexo printing on corrugated is standard, and litho-laminated or printed liners give higher-quality graphics.

How do I know which strength I need?

Run a transit test (for example ISTA-3A) with your product and box, then choose the wall that passes with margin.
