30 x 30 x 12" Double Wall Boxes

These 30 x 30 x 12 inch double wall corrugated boxes are built from ECT-48 double wall kraft corrugated board. That construction makes them a reliable choice when single-wall boxes fall short on protection or load-bearing capacity.

The wide square footprint handles oversized, bulky, or awkwardly shaped items that exceed standard small-parcel box dimensions. Typical applications include industrial equipment components, large consumer goods, automotive parts, and dense or high-value shipments routed through manufacturing, distribution, and e-commerce fulfillment operations.

Each box weighs approximately 7.0 lbs and arrives flat, keeping storage footprint minimal until boxes are needed at the pack station. Sold in bundles of 5, ships via parcel carrier.
