11 1/4 x 8 3/4 x 6" Heavy-Duty Boxes

These 11 1/4 x 8 3/4 x 6 inch corrugated boxes are built from ECT-44 single wall kraft corrugated board, delivering approximately 40% greater stacking strength and puncture resistance than standard ECT-32 cartons. That added structural integrity makes them a reliable choice for denser or heavier product loads that push past what standard shipping boxes can handle.

The mid-range footprint suits a broad set of product types found in e-commerce fulfillment, manufacturing, retail distribution, and industrial shipping — anywhere contents are compact but heavy enough to stress a lighter carton. At 0.592 lbs, the box itself contributes minimal dead weight while still protecting demanding loads.

Boxes ship and store flat, reducing floor space requirements until they are needed at the packing station. The ECT-44 single wall construction uses a standard C-flute configuration. Each bundle contains 25 boxes.
