16 x 16 x 16" ECT-71 Heavy-Duty Double Wall Boxes

These 16 x 16 x 16 inch double wall corrugated boxes are built from ECT-71 kraft board, delivering heavy-duty compression resistance and stacking strength for demanding transit and storage conditions. The cubic interior format maximizes usable volume for dense, bulky, or high-value contents, while the reinforced double wall construction maintains structural integrity under load.

A 140 lb per carton rating makes these boxes well-suited for industrial components, automotive parts, bulk consumer goods, and heavy retail merchandise. E-commerce fulfillment centers, manufacturers, and distribution operations rely on this grade when standard single-wall cartons cannot meet load or stacking requirements.

Constructed to ECT-71 double wall specification, these cartons satisfy carrier and program requirements mandating elevated board grades for heavier loads. Each unit weighs approximately 3 lbs, keeping tare weight low relative to carrying capacity. Available in bundles of 15 and ships via parcel carrier.
