28 x 18 x 18" Double Wall Boxes

These 28 x 18 x 18" corrugated boxes are constructed from ECT-48 double wall kraft corrugated board, delivering reinforced compression strength and puncture resistance that standard single wall construction cannot match. The dual-layer flute structure absorbs handling stress and stacking loads that would compromise lighter-duty boxes.

The generous interior length makes these boxes practical for bulky or oddly shaped items in e-commerce fulfillment, industrial parts shipping, retail distribution, and manufacturing operations where heavier or dense loads require a more robust enclosure. The interior depth and width also support organized internal packing with dividers or foam inserts.

Each box weighs approximately 3.584 lbs and ships flat to minimize storage footprint. Sold in bundles of 10, these boxes are parcel-friendly and suitable for freight and pallet distribution channels alike.
