Shipping a product that needs to survive a warehouse, a delivery van, and a customer’s doorstep? Custom Corrugated Boxes from Prime Custom Packaging are built for exactly that job. Every order ships free across the United States. Zero minimum order quantity and a free dieline come standard from our in-house team. Whether you need a single-wall mailer or a triple-wall export case, we match the board to your product.
Custom Corrugated Boxes use a fluted inner layer sandwiched between two flat liners. That wavy middle layer is what separates corrugated board from plain paperboard. It creates air pockets that absorb shock and resist crushing under stacked weight. Retailers, manufacturers, and e-commerce brands all rely on this structure for shipping, storage, and bulk transport. Getting the flute size and wall count right matters more than most buyers realize.
Flute size controls how a box performs under pressure, cushioning, and print quality.
A-flute measures roughly 4.0 to 4.8mm thick, the tallest common flute. It gives the strongest cushioning against impact, which suits fragile items.
B-flute runs about 2.5mm thick. It balances stacking strength with a smoother surface, ideal for retail-facing cartons.
C-flute sits between A and B at roughly 3.2 to 4.0mm. Most standard shipping boxes in this category use C-flute by default.
E-flute and F-flute run thinner, from about 0.8mm to 1.8mm. Both suit small retail boxes and detailed print work where flute lines would otherwise show through.
Wall count is the biggest factor in how much weight a corrugated box can carry.
| Wall Type | Board Thickness | Typical Weight Capacity | Common Use |
| Single-wall | 3-5mm | 20 to 120 lbs | Standard shipping, retail mailers |
| Double-wall | 5-7mm | 80 to 180 lbs | Heavier goods, stacked storage |
| Triple-wall | 7-10mm | 240+ lbs | Industrial, export, palletized freight |
Our Single-wall Corrugated Boxes cover most standard shipping needs at the lowest material cost. When a product needs more stacking strength, our Double-wall Corrugated Boxes add a second flute layer without doubling the price. For the heaviest industrial loads, our Triple-wall Corrugated Boxes replace wood crates in many warehouse operations.
Custom Corrugated Boxes describe ply count and wall count from two different angles. A 3-ply board is single-wall, a 5-ply board is double-wall, and a 7-ply board is triple-wall. Each additional ply adds one flute layer and one liner. Our Custom 3 Ply Corrugated Boxes suit lightweight retail shipments. Our Custom 5 Ply Corrugated Boxes step up to mid-weight industrial goods. Our Custom 7 Ply Corrugated Boxes handle the heaviest freight and long-distance export shipping.
Beyond wall count, the Custom Corrugated Boxes style itself determines how a product loads, closes, and displays.
Regular slotted construction is the most common corrugated style. Top and bottom flaps meet at the center and seal with tape or glue. Our Custom Slotted boxes line covers this standard shipping format at any size.
A telescopic box uses a separate lid that slides over the base like a shoebox. This style suits products needing a cleaner presentation than tape-sealed flaps. Our Custom Telescopic boxes line builds this two-piece structure to your dimensions.
Die-cut construction folds from a single flat sheet with no separate lid or extra glue joints. Our Custom Die Cut Corrugated Boxes line suits inserts, trays, and display-ready packaging.
Folder boxes fold flat for storage and pop into shape at the point of use. Our Custom Folder Boxes line works well for apparel, flat goods, and subscription kits.
Mailer boxes use a self-locking, tuck-style closure that skips tape entirely. Our Custom Corrugated Mailer Boxes line has become the standard for direct-to-consumer e-commerce brands.
We build every box to your exact product dimensions, but most orders fall into a few common ranges.
| Category | Typical Size Range | Common Wall Type |
| Small retail mailer | 6 x 4 x 4 in to 10 x 8 x 6 in | Single-wall |
| Standard shipping carton | 12 x 12 x 12 in to 18 x 14 x 12 in | Single or double-wall |
| Bulk storage box | 20 x 20 x 20 in to 24 x 18 x 18 in | Double-wall |
| Industrial and export crate | Custom to pallet or freight spec | Triple-wall |
Offset printing suits larger production runs where color consistency matters across thousands of units. Digital printing works better for shorter runs or frequent design changes. We match CMYK for full-color artwork and PMS for a locked brand color across every reorder. Kraft board takes ink differently than white liner, so we calibrate each file to the stock you choose. Our Custom Printed Corrugated Boxes line covers full-color branding across any wall type or ply count.
Gloss and matte lamination both protect printed artwork from handling and moisture. Aqueous coating adds a lower-cost protective layer for high-volume runs. Spot UV and foil stamping highlight a logo without adding weight to the structure. Most corrugated finishes prioritize function first, since these boxes handle real shipping stress.
The right combination of wall count, flute size, and box style depends on what you are shipping.
| What You’re Shipping | Recommended Wall Type | Recommended Style |
| Light retail goods, direct mail | Single-wall, B or C-flute | Mailer or slotted |
| Mid-weight products, subscription boxes | Single or double-wall | Folder or slotted |
| Heavy or fragile industrial goods | Double-wall, A-flute | Telescopic or die-cut |
| Palletized freight, export shipping | Triple-wall | Slotted, reinforced |
Zero minimum order quantity applies to every Custom Corrugated Boxes wall type and style on this page. Standard corrugated orders ship in four to eight business days after proof approval. Rush production is available for time-sensitive launches. Shipping stays free across the United States, regardless of order size or wall count.
Our in-house team builds your dieline at no charge, matched to your product dimensions and shipping requirements. We flag any structural weak point before your order goes to press. An oversized flap or a thin flute choice both count. 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 for your wall type | Confirms the box holds its stacking weight |
| Dieline accuracy | Within plus or minus 1/16 inch of approved dieline | Prevents loose flaps or a box that won’t seal |
| Print registration | Multi-color alignment checked on press sheet | Avoids blurred or shifted artwork on kraft or white stock |
