Description

These 18 x 18 x 18 inch corrugated boxes are built from ECT-44 single wall kraft corrugated board — approximately 40% stronger in stacking strength and compression resistance than standard ECT-32 construction. At 2.36 lbs per box, the added weight reflects heavier liner and flute materials engineered for demanding load requirements.

The cubic format suits e-commerce fulfillment, industrial parts shipping, retail replenishment, and warehouse storage where consistent, predictable carton geometry matters. Equal length, width, and height simplify palletizing, improve stack stability, and reduce the likelihood of shifting during transit. These are a practical step up for operations that have experienced damage or compression failures with standard-weight corrugated.

Each bundle contains 20 boxes shipped flat for efficient storage in tight receiving areas. The ECT-44 rating is achieved through single-wall construction, keeping the carton stackable without the bulk of double-wall board. Orders ship via parcel carrier.
