20 x 16 x 14" Heavy-Duty Boxes

These 20 x 16 x 14 inch heavy-duty corrugated boxes are built from ECT-44 single wall kraft corrugated board, delivering meaningfully greater compression strength and stacking performance than standard ECT-32 cartons. The elevated ECT rating supports heavier contents and multi-unit loads where board integrity under pressure is a priority.

The interior footprint suits a range of demanding pack-out scenarios: outbound e-commerce shipments with dense or fragile contents, manufacturing parts packaging, retail replenishment cartons, and warehouse pick-and-pack operations where consistent box performance reduces damage claims.

At 2.156 lbs, the heavier board stock is evident on the line. Boxes arrive flat-packed in bundles of 15, minimizing staging footprint and allowing teams to pull inventory incrementally. Each bundle ships via parcel carrier.
