These 18 x 12 x 6 inch double wall corrugated boxes are built from ECT-48 kraft corrugated board, delivering heavier load capacity and stacking strength than standard single wall cartons. The double wall construction adds a second medium and liner layer, giving the carton greater resistance to crushing, puncture, and deformation under load.

The added structural integrity makes these boxes a reliable choice for dense or heavy industrial components, fragile goods requiring extra protection, and products moving through e-commerce fulfillment, manufacturing distribution, or retail supply chains where stacked storage and extended transit cycles put cartons under sustained pressure.

Boxes are sold in bundles of 15 and ship flat to minimize storage footprint. Each box weighs approximately 1.189 lbs. These boxes ship via parcel carrier, making them accessible for standard replenishment orders.
