40 x 30 x 30" Double Wall Boxes

These 40 x 30 x 30 inch double wall corrugated boxes deliver the structural integrity required for heavy, bulky, or high-value freight. ECT-48 double wall kraft corrugated board, delivering measurably greater puncture resistance, compression strength, and load-bearing capacity than standard single wall cartons. The double wall construction is the defining advantage here, making these boxes capable of protecting heavier or more fragile contents through demanding transit conditions.

Applications include machinery component shipments, industrial equipment parts, bulk consumer goods, and consolidated multi-item pallets. Manufacturers, distributors, and large-scale fulfillment operations rely on this size and wall configuration when cargo dimensions or weight push beyond what lighter-duty cartons can reliably contain and protect in transit.

Each box weighs approximately 10.26 lbs and ships flat to reduce storage footprint in receiving and staging areas. Sold in bundles of 5. Due to their size, these boxes require freight delivery.
