These 30 x 30 x 16 inch double wall corrugated boxes are built from ECT-48 double wall kraft corrugated board, delivering the stacking strength and puncture resistance that single wall construction cannot match at larger dimensions. The double wall specification makes these boxes a reliable choice when contents are heavy, high-value, or require extra protection during transit and storage.

The large square footprint combined with a 16 inch depth suits bulky industrial components, automotive parts, bulk consumer goods, and oversized e-commerce shipments. Manufacturers, distributors, and fulfillment operations handling heavy or irregularly sized products will find this format particularly practical for both outbound shipping and internal warehouse transfers.

Each box ships flat and is sold in bundles of 5. At approximately 8 lbs per box, the board weight reflects the added material in double wall construction. This format ships via parcel carrier.
