12 x 12 x 6" Heavy-Duty Boxes

These 12 x 12 x 6 inch heavy-duty corrugated boxes are built from ECT-44 single wall kraft corrugated board, delivering approximately 40% greater compression and stacking strength than a standard ECT-32 box of the same footprint. That added wall strength translates to meaningful column load performance without a significant weight penalty at 0.81 lbs per unit.

The square 12 x 12 inch base and 6 inch depth make these boxes practical for e-commerce fulfillment, retail replenishment, automotive parts distribution, and light industrial shipping — anywhere moderately deep items need secure containment. The cubic format minimizes void fill requirements for products that would rattle in a taller carton.

Constructed with a flute designation suited to single-wall heavy-duty applications, ECT-44 is especially effective for palletized stacking, multi-unit outbound shipments, and environments where puncture resistance is a priority over standard-duty board. Bundles of 25 ship flat.
