Double-Wall Kraft Shipping Boxes

These boxes are built for shipping or storing long, narrow items that need extra protection. The double-wall corrugated construction resists crushing and punctures better than single-wall alternatives. Each pack contains ten boxes ready for assembly. They suit warehouses, fulfilment centres and anyone mailing oversized products.

Strength and handling in daily use

The double-wall kraft board handles normal stacking loads without bowing. Taped seams stay secure during transit and the material resists minor moisture exposure. No special tools are required to erect or seal the boxes. They ship flat to save storage space before use.

Fit in your packing workflow

The 40 x 12 x 12 inch interior accommodates elongated goods such as rods, tubes or rolled textiles. Flat-packed bundles free up shelf room until you need them. Ten per pack lets you stage orders without frequent reordering. They work with standard packing tape and void fill.

Questions about this item

How do I assemble the 40x12x12 double-wall boxes and what step do people often miss?

Fold the scored flaps inward, then tape the bottom centre seam and both edge seams; the step most people skip is sealing the edge seams, which keeps the double-wall corners from splitting under load.

What part of the 40x12x12 Kraft boxes will need replacing first during extended storage?

The double-wall corrugated board resists crushing, but the kraft liner absorbs humidity over time; once the outer liner feels damp or shows dark spots, the box loses stacking strength and should be swapped out.

What is the first limit you hit when stacking the 40x12x12 double-wall boxes long-term?

The 12-inch depth means the stack’s centre of gravity stays low, so the practical limit is the bottom box’s double-wall compression rating — once the lower flaps bow, the column becomes unstable.
