40 x 20 x 20" Double Wall Boxes

This 40 x 20 x 20 inch double wall corrugated box is constructed from ECT-48 double wall kraft board, delivering substantially greater puncture resistance, stacking strength, and load-bearing capacity than single wall alternatives. The large interior footprint  is purpose-built for bulky, elongated, or multi-unit loads that standard mid-range cartons cannot accommodate.

The ECT-48 double wall rating makes these boxes a strong fit for industrial manufacturers shipping dense or irregularly shaped components, distributors moving oversized retail goods, and e-commerce operations fulfilling large-format orders that require reliable stack protection during transit and warehouse storage.

Each box weighs 5.812 lbs and ships flat to minimize inbound storage requirements. Sold in bundles of 5, making them practical for operations that need to manage per-unit packaging costs without committing to full-pallet quantities. Ships via parcel where carrier weight and dimensional limits are met.
