18 x 12 x 12" Double Wall Boxes

These 18 x 12 x 12 inch double wall corrugated boxes are built from ECT-48 double wall kraft corrugated board, delivering meaningfully greater puncture resistance, stacking strength, and crush protection than standard single wall construction. The double wall configuration is the defining advantage here making these boxes a reliable choice when ECT-32-B or ECT-32-C boxes have reached their structural limits.

These boxes are well matched to industries and operations where product weight or density puts real stress on packaging: industrial parts distribution, hardware and tools, bottled or canned goods, automotive components, and dense retail merchandise. They handle manual packing lines efficiently while providing the wall strength that heavier SKUs demand.

Each box ships flat and is sold in bundles of 15, keeping inbound storage compact at high-volume pack stations. Each carton weighs approximately 1.868 lbs.
