Custom rectangular boxes are the everyday folding-carton format behind most US retail SKUs — the four-sided, six-panel print canvas that fits cosmetics, supplements, food, electronics, apparel accessories, and thousands of consumer products. We print rectangular cartons in tuck-end, seal-end, sleeve, and window formats, in SBS, kraft, and rigid options, with runs from 100 units.
For US consumer-product brands, retailers, and DTC programs that need the standard, high-utility folding-carton footprint at flexible run sizes.
About Custom Rectangular Boxes
The default retail packaging format
If a rectangular box did not exist, most of US retail would have to invent it. The four-sided, six-panel form gives designers a clean print canvas on every visible face, stacks predictably on a shelf, packs efficiently into a shipping master, and fits almost any product that is not spherical, cylindrical, or oddly shaped. We print custom rectangular boxes across every category and every construction type — from lightweight folding cartons to rigid two-piece gift boxes.
Rectangular box constructions
- Tuck-end cartons (straight and reverse): the everyday folding format — quick to assemble, cost-effective, and print-friendly.
- Seal-end cartons: glued top and bottom flaps for tamper-evident retail — the food, pharma, and supplement standard.
- Sleeve-and-tray boxes: a printed sleeve over an inner tray for a considered open.
- Window boxes: die-cut windows that show product through the carton.
- Rigid rectangular boxes: chipboard-wrapped luxury construction for gifting and prestige retail.
Sizing, stock, and finish
Rectangular is a footprint, not a spec — the right stock and finish follow the product weight, the retail context, and the price point. Small cosmetic cartons run on 14pt SBS; everyday retail sits at 18pt; larger and heavier products step up to 20pt or 24pt or corrugated. Any of these takes matte, gloss, soft-touch, or textured lamination, plus foil stamping, embossing, spot UV, and window die-cuts.
Print and color
We print full-color CMYK with optional Pantone spot matching at no extra cost. Multi-SKU brands benefit from Pantone lock-in — a shared spot color across a whole product line keeps the range reading as one brand even as the individual box art varies.

Why US brands choose us for custom rectangular boxes
Custom Box Printing manufactures custom rectangular boxes from our US production facility, with free standard shipping anywhere in the contiguous United States and a 7–10 business day turnaround. We've printed custom rectangular boxes for solo founders launching their first product line, growing direct-to-consumer brands placing 5,000-unit runs, and established retail brands with 50,000+ unit production schedules — and we treat all three the same: low MOQs (100-unit runs), free design support, no setup or die-plate charges, and a 3D digital mockup before anything goes to press.
Every custom rectangular boxes order includes free in-house dieline and artwork support — our US-based designers will polish your existing files, or build a custom dieline from scratch to fit your exact product dimensions. We send you a 3D mockup to confirm look and proportions before production. For color-critical work, request a physical sample free — let’s talk about a customized sample so you can confirm the look before a full run.
Materials, print, and finish options
Rectangular boxes are the most versatile folding-carton family, and they take the widest range of stocks. Most retail rectangular cartons print on 14pt to 24pt SBS (bright white, color-accurate CMYK) or on kraft (unbleached, eco-forward). For heavier or larger footprints, we step up to 24pt board or corrugated construction; for luxury and gifting, we build rigid rectangular boxes with chipboard cores wrapped in printed art paper.
Available finishes include:
- Lamination: Gloss, matte, soft-touch, or velvet finish for a premium hand-feel.
- Foil stamping: Gold, silver, copper, or custom foil colors for high-visibility brand marks.
- Embossing & debossing: Tactile raised or recessed surface effects on logo or key artwork.
- Spot UV: Selective gloss coating that creates contrast against matte areas.
- Eco-friendly options: Recycled kraft, widely recyclable paperboard and water-based inks.
- Compliance: soy-based inks; child-resistant-style constructions for CBD/cannabis on request.
