Double Wall Cardboard Boxes

When durability, safety, and load strength matter, double wall cardboard boxes are one of the most reliable packaging solutions available today. They are widely used for shipping, storage, warehousing, and relocation because they provide far greater protection than standard single wall boxes.

This guide explains what double wall cardboard boxes are, how they differ from single wall boxes, available sizes, best use cases, pricing factors, and how to choose the right box, so buyers can make informed decisions without overpaying or risking damage.

What Are Double Wall Cardboard Boxes?

Double wall cardboard boxes are made using two layers of corrugated fluting sandwiched between three layers of linerboard, creating a total of five layers. This structure delivers high resistance to crushing, punctures, and impact during handling or transit.

Compared to single wall boxes, double wall boxes offer:

• Higher stacking strength

• Better shock absorption

• Improved load-bearing capacity

• Greater protection for heavy or fragile goods

The corrugated layers act as cushions that absorb pressure and vibration, which is essential during courier handling, pallet stacking, and long-distance transport.

Because of these characteristics, cardboard boxes double wall construction is widely used in e-commerce, manufacturing, logistics, and household moving.

Double Wall vs Single Wall Cardboard Boxes

The main difference lies in strength and weight capacity.

• Lightweight items

• Documents, clothing, soft goods

• Loads under 15 kg

Double wall cardboard boxes are preferred when:

• Items exceed 20 kg

• Products are fragile or high value

• Boxes will be stacked or shipped long distances

Heavy duty double wall cardboard boxes can support 25 kg, depending on size, material quality, and edge crush test (ECT) rating.

• Returns and replacements

• Customer complaints

The small difference in box cost is often recovered by avoiding a single damaged shipment.
