Single-wall Corrugated Boxes from Prime Custom Packaging are the everyday standard behind most retail and e-commerce shipping, and for most products, they’re the right starting point before considering anything heavier. One flute layer sits between two liners, keeping material cost low while still resisting the everyday bumps of warehouse handling and last-mile delivery. This board is also fully recyclable, which makes it an easy sustainability win for brands that care about their packaging footprint. Every order ships free across the United States with a free dieline and zero minimum order quantity, so testing a new size costs nothing extra. We cut each box to your exact product dimensions and can add full-color printing directly to the board.

Most boxes stacked in a warehouse today share one thing in common. Single-wall Corrugated Boxes from Prime Custom Packaging are the everyday standard behind e-commerce and retail shipping. Every order ships free across the United States. Zero minimum order quantity and a free dieline come standard from our in-house team. Wholesale retailers and small businesses order single-wall boxes in bulk for lightweight shipping.
Single-wall Corrugated Boxes account for most of what moves through fulfillment centers coast to coast. One flute layer between two liners keeps material cost low while still resisting crushing. This balance of price and protection explains why Single-wall Corrugated Boxes dominate general retail shipping. Custom packaging buyers usually start their search here before considering anything heavier. Most quotes we run begin with this exact board weight, adjusted only once product details are confirmed.
Corrugated board is one of the most recycled packaging materials in the United States. Single-wall Corrugated Boxes use less raw material than double or triple-wall construction. Brands focused on sustainability messaging often lead with this lower material footprint. The board itself remains fully recyclable through standard municipal programs nationwide. That lighter footprint also lowers shipping weight, which trims freight cost across large order volumes. Many retailers now list recycled content percentages directly on packaging, and we can print that messaging on request.

We cut every box to your product’s exact dimensions, but most orders fall into familiar ranges.
| Category | Typical Size | Suggested Flute |
| Small e-commerce mailer | 8 x 6 x 4 in (203 x 152 x 102 mm) | B-flute |
| Standard retail carton | 12 x 12 x 12 in (305 x 305 x 305 mm) | C-flute |
| Larger apparel box | 16 x 12 x 6 in (406 x 305 x 152 mm) | B or C-flute |
This construction goes by another common term in the packaging industry. Ply count calls it 3-ply, while wall count calls it single-wall. Our Custom 3 Ply Corrugated Boxes line covers this identical board under the ply-count term. Both terms describe the exact same product on this page.
B-flute measures roughly 2.5mm and gives a smooth, print-friendly surface. C-flute runs about 3.2 to 4.0mm and adds more cushioning for general shipping. E-flute drops to around 1.0 to 1.8mm, suited to small retail boxes with detailed graphics. We recommend a flute once we know your product weight and how fragile it is. Getting this choice right the first time avoids reprint costs down the line.
Offset printing works well for larger production runs with consistent color needs across every carton. Digital printing suits shorter runs or frequent design changes between seasons. We match CMYK for full-color artwork and PMS for a locked brand color across every reorder. Brands wanting maximum branded coverage should also see our Custom Printed Corrugated Boxes line.
A standard slotted carton is the most common Single-wall Corrugated Boxes format for shipping. Our Custom Slotted boxes line builds this format at any size, using the same board weight discussed above. Direct-to-consumer brands often prefer our Custom Corrugated Mailer Boxes line for a tape-free closure. Apparel and flat goods fit well in our Custom Folder Boxes line. Structural trays and inserts are available through our Custom Die Cut Corrugated Boxes line.
Heavier or fragile products often outgrow single-wall protection. Our Double-wall Corrugated Boxes line adds a second flute layer for extra strength. It is also sold as our Custom 5 Ply Corrugated Boxes line. Industrial freight belongs in our Triple-wall Corrugated Boxes line, also known as our Custom 7 Ply Corrugated Boxes line. Presentation-focused shipments should also review our Custom Telescopic boxes line for a cleaner two-piece build.
Zero minimum order quantity applies to every order on this line. Standard orders ship in four to six business days after proof approval. Rush production is available for time-sensitive launches. Shipping stays free across the United States, regardless of order size. Private-label sellers and eco-conscious brands both rely on this recyclable, retail-ready carton.
Our in-house team builds your dieline at no charge, sized to your exact product and shipping needs. We recommend the right flute and ECT rating during the free design stage for every Single-wall Corrugated Boxes order. Physical samples are available on request before you commit to a full run.
| Check | What We Verify | Why It Matters |

| 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 | Keeps artwork sharp on kraft or white liner |
