13 x 13 x 13" Heavy-Duty Boxes

This 13 x 13 x 13 inch single wall corrugated box is manufactured from ECT-44 kraft board, delivering approximately 40% greater stacking strength and crush resistance than standard ECT-32 cartons. The cubic format makes efficient use of interior volume, and the elevated ECT rating supports demanding palletizing environments and extended transit chains where column stacking integrity is critical.

These boxes are a practical choice for warehouses, fulfillment centers, manufacturers, and distributors that regularly ship heavier or more fragile goods but want to avoid the added material cost and weight of double-wall construction. They perform reliably in retail replenishment, industrial parts shipping, and e-commerce operations where product protection during multi-stop transit matters.

Board spec is ECT-44 single wall kraft with a C-flute designation. Each box weighs approximately 1.285 lbs and ships flat in bundles of 25, allowing efficient storage until needed.
