Double-wall Corrugated Boxes from Prime Custom Packaging sit right between everyday shipping cartons and heavy industrial crates, built for products that punish standard single-wall board. Two separate flute layers between three liners give this structure roughly double the crush resistance, which matters once cases start stacking four or more high or a shipment passes through several handoffs. It’s the board we recommend once a product crosses about 65 pounds per case, where single-wall board starts to buckle at the corners. Every order ships free across the United States, with a free dieline and zero minimum order quantity on every size we cut. Our in-house team sizes each box to your exact product dimensions rather than a generic template, so you’re not paying for wasted material.

A box that collapses under its own stack costs more than the extra board would have. Double-wall Corrugated Boxes from Prime Custom Packaging solve that exact problem. Every order ships free across the United States. Zero minimum order quantity and a free dieline come standard from our in-house team. This line sits right between standard shipping cartons and heavy industrial crates. Wholesale buyers and e-commerce brands order double-wall boxes in bulk for everyday shipping.
Does your product weigh more than 65 pounds per case? Will boxes stack four or more high in a warehouse? Does the shipment travel through multiple handoffs before reaching its destination? A yes to any of these usually means Double-wall Corrugated Boxes are the right call. Single-wall board starts to buckle exactly where these questions point. A failed case mid-shipment costs far more than the small board upgrade.
Double-wall board sandwiches two separate flute layers between three flat liners. One flute alone handles moderate pressure from a single direction. Two flutes, stacked and offset, resist compression evenly across the whole panel. That structural difference is what lets Double-wall Corrugated Boxes carry two to three times the weight of single-wall board.
Wall count and ply count describe this same board differently. Wall count calls it double-wall, while ply count calls it 5-ply. Our Custom 5 Ply Corrugated Boxes line covers this identical construction under the ply-count term. Either search term brings a buyer to the same board.
Moving companies and self-storage brands rely heavily on this weight class. Double-wall Corrugated Boxes hold books, kitchenware, and dense household items without buckling in transit. Long-term storage also benefits from the extra rigidity, since stacked boxes sit under weight for months at a time. Commercial movers often standardize their entire inventory on this single board weight. That consistency simplifies both purchasing and warehouse space planning across a large fleet of storage units.
We build every box to your product’s exact dimensions, but common ranges apply.
| Category | Typical Size | Suggested ECT |
| Moving and storage box | 18 x 18 x 16 in (457 x 457 x 406 mm) | 44 ECT |
| Appliance or electronics box | 22 x 18 x 14 in (559 x 457 x 356 mm) | 44 to 55 ECT |
| Bulk industrial case | 24 x 20 x 18 in (610 x 508 x 457 mm) | 55 ECT |
| ECT Rating | Approximate Weight Capacity |
| 44 ECT | Up to 95 lbs per case |
| 55 ECT | Up to 120 lbs per case |
Offset printing suits larger production runs where color needs to stay consistent across every unit. Digital printing works better for shorter runs or seasonal changes. We match CMYK for full-color artwork and PMS for a locked brand color. Brands wanting heavier branded coverage should see our Custom Printed Corrugated Boxes line for full-panel graphics.
A slotted structure remains the standard format for this weight class. Our Custom Slotted boxes line covers that format at any size, built to the same double-wall specification. Products needing a separate lid should see our Custom Telescopic boxes line instead. Structural inserts and trays are also available through our Custom Die Cut Corrugated Boxes line.
Lighter shipments rarely need this extra board. Our Single-wall Corrugated Boxes line covers that lighter range at a lower cost. It is also sold as our Custom 3 Ply Corrugated Boxes line. Palletized freight and export shipping typically exceed what double-wall board can carry. Our Triple-wall Corrugated Boxes line steps up to that heavier class. It is also sold as our Custom 7 Ply Corrugated Boxes line.
Flat goods that fold for storage work well in our Custom Folder Boxes line, built in double-wall on request. Direct-to-consumer brands can also use our Custom Corrugated Mailer Boxes line for heavier items shipped straight to a customer’s door. Both lines take the same double-wall specification without any structural changes required.
Zero minimum order quantity applies to every Double-wall Corrugated Boxes order. Standard orders ship in six to eight business days after proof approval. Rush production is available for tight deadlines. Shipping stays free across the United States, regardless of order size or weight. Private-label fulfillment centers and retail-ready warehouses both choose this sustainable corrugated structure.
Our in-house team builds your dieline at no charge for every Double-wall Corrugated Boxes order. We match it to your product weight and stacking requirements. We recommend the right flute pairing and ECT rating before your order goes to press. Physical samples are available on request before you commit to a full production run.
| Check | What We Verify | Why It Matters |
| Edge crush strength | Tested against the ECT rating you selected | Confirms the box holds its stacking weight |
| Flute bond integrity | Checked across both flute layers | Prevents delamination under repeated handling |
| Dieline accuracy | Within plus or minus 1/16 inch of approved dieline | Prevents loose flaps or a box that won’t seal |
