12 x 12 x 12" ECT-71 Heavy-Duty Double Wall Boxes

These 12 x 12 x 12 inch double wall corrugated boxes are built to ECT-71 specifications, delivering substantially greater compression strength and puncture resistance than standard single wall cartons. The reinforced double wall construction handles heavier loads and dense contents that would compromise lighter-duty packaging, making these a reliable choice when product protection is the priority.

Applications include e-commerce fulfillment of heavy goods, manufacturing and industrial parts distribution, automotive components, tools and hardware, and retail replenishment of dense consumer products. The cubic 12 inch format stacks uniformly on pallets and integrates cleanly into shelving systems, supporting consistent footprint management in warehouse and distribution environments.

Each box is constructed from ECT-71 double wall kraft corrugated and weighs approximately 1.727 lbs, reflecting the added structural mass of the double wall build. The 140 lb parcel capacity rating supports demanding outbound freight requirements. Sold in bundles of 15.
