18 x 18 x 18" Double Wall Boxes

These 18 x 18 x 18 inch double wall corrugated boxes are built from ECT-48 kraft corrugated board, which places two independent flute layers between three liners for substantially greater rigidity and puncture resistance than single wall construction at the same size.

The cubic interior and reinforced walls make these boxes well suited for e-commerce fulfillment of heavy goods, manufacturing parts distribution, export packaging, and any application where contents demand protection beyond what ECT-32 single wall cartons provide. Automotive components, tools, electronics, and dense retail products are common fits.

Each box weighs approximately 3.2 lbs and ships flat to minimize storage footprint on arrival. Bundles of 10 allow efficient inventory management whether replenishing a packing line or stocking a distribution center.
