Custom Slotted Boxes from Prime Custom Packaging are the standard behind most shipping worldwide, built as a Regular Slotted Container that folds from one flat sheet with four flaps top and bottom. This configuration wastes almost no material and assembles fast on any packing line, which is exactly why it dominates general shipping across so many industries. We offer standard, full overlap, and center special flap styles depending on how much stacking strength your load needs. Every box ships free across the United States, with a free dieline and zero minimum order quantity on any size or flap style. Full-color offset or digital printing is available on any panel if you want branding on the box itself. Get a free quote today and our team will confirm the right flap style for your product weight.
If you picture a cardboard box, you are probably picturing this one. Custom Slotted Boxes from Prime Custom Packaging are the standard behind most shipping worldwide. Every order ships free across the United States. Zero minimum order quantity and a free dieline come standard from our in-house team. This is the most common corrugated structure in the industry. Wholesale distributors order regular slotted boxes in bulk for standard freight and storage.
A slotted box, known industry-wide as RSC, folds from one flat sheet. It has four flaps on top and four on bottom. Top flaps meet at the center and seal with tape or glue. Custom Slotted Boxes use this configuration because it wastes almost no material and assembles fast on any packing line. That efficiency is why this style dominates general shipping.
The standard RSC has all four flaps meeting at the center without overlap. This is the most economical slotted style and covers most general shipping needs across every industry we serve.
Full overlap flaps extend the width of the box, adding real stacking strength. Heavier products benefit from this reinforced top and bottom panel.
This style uses shorter outer flaps and longer inner flaps that meet exactly at center. It suits products needing a tighter, cleaner seal along the entire top panel.
Custom Slotted Boxes ship flat before assembly, saving warehouse space and inbound freight cost. Assembly takes seconds on a standard packing line, whether by hand or machine. Material efficiency keeps per-unit cost lower than most other structural styles. These three factors combine to make Custom Slotted Boxes the default choice across e-commerce and retail. High-volume shippers in particular value the speed this format adds to a packing line.
We build every box to your exact product dimensions, but common ranges cover most orders.
| Category | Typical Size | Common Wall Type |
| Small retail carton | 10 x 8 x 6 in (254 x 203 x 152 mm) | Single-wall |
| Standard shipping box | 16 x 12 x 10 in (406 x 305 x 254 mm) | Single or double-wall |
| Bulk case | 20 x 16 x 14 in (508 x 406 x 356 mm) | Double-wall |
| Industrial crate | Custom to pallet spec | Triple-wall |
Custom Slotted Boxes build in any wall count we manufacture. Our Single-wall Corrugated Boxes line covers lighter shipments at the lowest cost. Our Double-wall Corrugated Boxes line adds stacking strength for mid-weight goods. Our Triple-wall Corrugated Boxes line handles the heaviest industrial freight in this same structural format.
Offset printing suits larger production runs where consistent branding matters across every case in the batch. Digital printing works better for shorter runs or frequent SKU changes between seasons. We match CMYK for full-color artwork and PMS for a locked brand color. Our Custom Printed Corrugated Boxes line covers full-panel branding on any slotted build.
Not every product suits a slotted box, even though it remains the default across most industries. Presentation-focused brands should review our Custom Telescopic boxes line for a lid-and-base design instead. Products needing precise internal shaping fit our Custom Die Cut Corrugated Boxes line better. Flat goods that fold for storage work well in our Custom Folder Boxes line. Direct-to-consumer brands often prefer our Custom Corrugated Mailer Boxes line for a tape-free closure.
Suppliers sometimes describe slotted boxes by ply count instead of wall count, which can confuse a first-time buyer. Our Custom 3 Ply Corrugated Boxes line matches single-wall board. Our Custom 5 Ply Corrugated Boxes line matches double-wall, and our Custom 7 Ply Corrugated Boxes line matches triple-wall. All three build in the same slotted format described on this page.
Zero minimum order quantity applies to every Custom Slotted Boxes order, regardless of wall count. Standard orders ship in four to eight business days after proof approval, depending on board weight. Rush production is available for time-sensitive launches. Shipping stays free across the United States on every order. Private-label warehouses and retail-ready shipping operations both rely on this eco-friendly structure.
Our in-house team builds your dieline at no charge, sized to your exact product dimensions. We recommend the right flap style and board weight 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 |
| Flap alignment | Checked against approved dieline | Prevents gaps or a box that won’t seal |
| Edge crush strength | Tested against the ECT rating for your wall type | Confirms the box holds its stacking weight |
| Print registration | Multi-color alignment checked on press sheet | Keeps artwork sharp across every panel |
