20 x 20 x 20" Heavy-Duty Boxes

These 20 x 20 x 20 inch heavy-duty corrugated boxes are built from ECT-44 single wall kraft corrugated board, delivering approximately 40% greater compression resistance than standard ECT-32 cartons. The cube format distributes load evenly across all six faces, making it especially effective for dense or heavy contents that would stress a conventional single-wall box.

The reinforced construction suits applications where standard cartons fall short: industrial parts shipping, wholesale beverage distribution, trade show equipment, and e-commerce fulfillment of bulky consumer goods. Operations running multi-tier pallet stacks benefit from the higher ECT rating, which maintains structural integrity under the compressive loads common in racked warehouse storage.

Each box weighs 3.21 lbs and ships flat for space-efficient storage. Sold in bundles of 10.
