22 x 22 x 22" Heavy-Duty Boxes

These 22 x 22 x 22 inch interior cubic corrugated boxes are built from ECT-44 single wall kraft corrugated board, delivering approximately 40% greater edge crush resistance than standard ECT-32 cartons. The equal-sided cubic format and heavier board construction — reflected in the 3.6 lb per-box weight — make this one of the more capable single wall options available at this size.

The reinforced build suits applications where loaded cartons will be palletized, stacked in storage, or subjected to the compressive stress of transit. Warehousing operations, manufacturing facilities, and retail distribution centers handling dense or heavy goods benefit most from the higher ECT rating, particularly when column-stacking multiple filled cartons.

Boxes are sold and shipped flat in bundles of 10, keeping floor storage compact and per-unit costs accessible for moderate-volume buying. The ECT-44 single wall board carries a flute designation consistent with standard C-flute geometry, contributing to the balance of puncture resistance and flat-crush performance. Orders ship via parcel carrier.
