Custom Folding Cartons

Folding Cartons: specifications

Folding Cartons: price breaks

How the estimated unit price of a 3×3×5" folding carton in SBS white paperboard (18pt) changes with quantity. Setup costs are spread over more boxes as the run gets longer, so the per-box price drops sharply in the first few tiers.

Popular sizes for folding cartons

Sizes are inside dimensions (length × width × height) in inches. Any custom size is available at no extra cost; these are simply the sizes brands order most.

Material options and how they affect price

Estimated unit price at 1,000 units for a 3×3×5" folding carton with full-color printing, by material. Material choice changes look, strength and recyclability as well as cost.

Printing options compared

How the print specification changes the estimated unit price of a 3×3×5" folding carton in SBS white paperboard (18pt). One- and two-color printing carries a small plate charge that matters less as quantities grow; full-color digital and offset printing have no plate charge in our model.

What is a folding carton?

A folding carton is a box made from a single sheet of paperboard that is printed, die-cut, creased and (usually) glued along one side seam, then shipped flat. At your packing line it is pushed open, the bottom is closed, the product goes in and the top is tucked or sealed. Folding cartons are the most common form of retail packaging in the world: cereal boxes, cosmetics cartons, tea boxes, medicine packs and toothpaste boxes are all folding cartons.

Their popularity comes from a rare combination of qualities. Paperboard prints with photographic sharpness, ships and stores flat, is light enough to keep freight costs down and is widely recyclable. Production is highly efficient at scale, and short runs are now practical thanks to digital printing and digital cutting. The cigarette pack is a well-known example of how precise high-volume folding carton engineering can be (see how a carton of cigarettes is built).

On this page you will learn how folding cartons are made, how to choose the board and structure, what to expect on price, and how to set up artwork that prints and folds perfectly.

How folding cartons are made

Understanding the production steps explains why some design choices cost more than others.

1. Sheeting and printing. Large sheets of paperboard are printed on an offset or digital press. Many cartons fit on one sheet, which is why setup cost is spread across the run.
2. Coating or laminating. An aqueous or UV coating, or a laminate film, is applied for protection and finish.
3. Embellishing. Foil stamping, embossing or spot UV are added in separate passes, each with its own tooling.
4. Die-cutting and creasing. A steel-rule die cuts the outline and presses crease lines so the carton folds cleanly.
5. Stripping. Waste board between cartons is removed.
6. Folding and gluing. A folder-gluer applies glue to the side seam (and the base, for auto-lock styles) and folds the carton flat.
7. Inspection and packing. Cartons are checked against the approved proof and packed flat in shipping cases.

Every extra step (a second foil, a window patch, an auto-lock base) adds machine time. That is why the cleanest designs are often the most economical.

Folding carton styles

For a detailed walkthrough of every style, see our box styles guide. The free Dieline Generator creates templates for reverse tuck, straight tuck and auto-lock cartons in your exact size.

Choosing paperboard for folding cartons

Paperboard grade is the foundation of carton quality. The three main families in North America are:

SBS: solid bleached sulfate

Made from bleached virgin fiber throughout, SBS is bright white on both sides, very smooth and strong for its weight. It gives the sharpest print, the cleanest folds and the most consistent finish for foils and embossing. It is the standard for cosmetics, pharmaceuticals, fragrance and premium retail. Grades are often written as C1S (coated one side) or C2S (coated both sides). Learn more about SBS paperboard.

CUK and kraft paperboard

Coated or uncoated unbleached kraft board has long, strong fibers and a natural brown color. It is very tough and tear resistant. Uncoated kraft gives a rustic, eco-forward look; coated kraft (CUK) has a white printable face over a brown back. See kraft paperboard.

CRB: coated recycled board

Made from recycled fiber with a white clay-coated face and a grey back. It prints very well, costs less than SBS and is the workhorse of food and household packaging. Whites are slightly less brilliant and folds can crack more easily on dark solid colors, so a laminate or careful color choice helps. See recycled paperboard.

Caliper guide

Printing folding cartons

Folding cartons are where print quality shines. Most runs use one of two methods:

• Offset lithography prints CMYK and Pantone spot colors at very high resolution with excellent color consistency. It is the most economical method from roughly 1,000–2,000 units up and the best choice for exact brand color matching. See offset printing.
• Digital printing prints directly from the file with no plates. It suits short runs, test markets, multiple SKUs and versioned or personalized cartons. See digital printing.

Color tips for cartons

• Specify Pantone for brand-critical colors, and approve a printed proof for exact matches.
• Use rich black (for example C40 M30 Y30 K100) for large black areas so they look deep, but keep small text in 100% K only to avoid registration blur.
• Watch dark solids on folds. Dark ink on the outside of a fold can crack and show white fibers. Lamination, a lighter color at the fold, or a suitable board grade reduces cracking.
• Barcodes should be 100% black on white or a light color, at nominal size, with quiet zones intact.

Coatings and finishes

For details on each, see our packaging finishes guide.

Sizing folding cartons

Folding cartons are specified by inside dimensions in the order Length × Width × Height (or Depth). For tuck end cartons, length and width form the tuck opening; height runs between the tucks.

• Measure the product at its largest points, including closures.
• Allow 1/16 to 1/8 in clearance per dimension for most products.
• Consider how the product goes in. Tall bottles go in through the end; wide items may need the opening on the larger face, which changes which dimension is "length".
• Test with a plain sample for critical fits such as glass dropper bottles or palettes.

Remember that board thickness affects fit: 24pt board takes up more space than 16pt. If you change caliper, ask for an updated dieline.

Folding carton pricing

The estimate table at the top of this page shows a 3 × 3 × 5 in carton. Costs depend on:

1. Sheet utilization. How many cartons fit on a press sheet. Odd sizes that waste board cost more per carton.
2. Quantity. Plates, make-ready and dies are spread over the run.
3. Board grade and caliper.
4. Number of colors and finishes, each a separate setup.
5. Structure. Auto-lock bottoms and windows add folder-gluer complexity.
6. Number of SKUs. Several designs can share a sheet (ganging) to save setup costs.

For comparison, here is a larger 4 × 4 × 6 in carton in recycled board:

Cost-saving ideas

• Gang SKUs: design several products to the same carton size so they print together.
• Pick a standard caliper (18pt) unless the product truly needs more.
• Limit foils to a logo-sized area.
• Choose RTE over STE or auto-lock when the product is light.
• Order for the season, not the month, if storage allows.

Use the Packaging Cost Calculator to compare scenarios.

Artwork setup for folding cartons

1. Start from the dieline for your exact size, style and caliper.
2. Keep live text 1/8 in (3 mm) inside cut and crease lines.
3. Add 1/8 in bleed beyond the cut line on all printed edges.
4. Leave glue areas unprinted (or knocked out) so the side seam bonds properly.
5. Set finishes as spot layers (foil, spot UV, emboss) at 100% in a named swatch.
6. Use 300 ppi images at final size and vector logos.
7. Outline fonts or package them.
8. Export PDF/X-1a or PDF/X-4 with bleed.

Folding cartons by industry

• Cosmetics and fragrance: SBS, soft-touch, foil, embossing, inserts. See cosmetic boxes and perfume boxes.
• Supplements and wellness: auto-lock cartons around bottles with clear regulatory panels. See supplement boxes.
• Food and beverage: CRB or SBS with food-safe coatings; windows for bakery. See food boxes.
• Tea and coffee: tuck cartons for tea bags, sleeves for gift sets. See coffee & tea boxes.
• CBD and hemp: cartons with room for compliance text and batch information. See CBD boxes.
• Soap and personal care: kraft cartons and sleeves. See soap boxes.

Folding cartons and sustainability

Paperboard cartons are made from renewable fiber, and CRB is made almost entirely from recycled fiber. Most cartons are accepted in US curbside recycling. To keep them that way, prefer aqueous coatings, keep laminations and foils modest, choose paper windows or no window when possible, and right-size the carton. If you make FSC claims, you need certified supply and the correct license code on pack; see our sustainable packaging guide.

Common folding carton mistakes

1. Choosing board by price alone. Too thin a board bulges and crushes; the saving disappears in returns and a poor shelf look.
2. Designing on a generic template that ignores your board's thickness and grain direction.
3. Heavy dark ink across folds without lamination, causing visible cracking.
4. Forgetting tuck clearance, so products scuff on the way in or tucks pop open.
5. Too little space for required information, discovered at the proof stage.
6. Not testing with the real product, especially for bottles with pumps or caps.
7. Ordering every SKU separately when sizes could be standardized to share dies and setup.

Questions to ask any carton supplier

When comparing quotes, ask:

• Which board grade and caliper is quoted?
• Is the price for printed one side or two?
• Which coating or lamination is included?
• Are dies, plates and setup included in the unit price?
• What is the production lead time after proof approval?
• What tolerance applies to quantity (overs and unders)?
• Is delivery included, and to which address?
• What proofs are provided (PDF, 3D, physical sample)?
• What happens if cartons do not match the approved proof?

Our quotes answer all of these up front; see pricing and our reprint guarantee.

Folding cartons and the supply chain

Folding cartons are delivered flat in counted bundles, packed in corrugated cases on pallets. Plan for:

• Storage: dry, flat, away from heat. Flat cartons take far less space than assembled boxes.
• Acclimation: let cartons adjust to the packing room for a day before use, especially in winter or humid summers, so they fold smoothly.
• First in, first out: use older stock first.
• Reorder lead time: typically 10–14 business days of production plus shipping; set reorder points accordingly.

From carton to shelf: secondary packaging

Cartons rarely travel alone. Plan how they ship:

• Inner packs and shipper cases hold multiple cartons for distribution.
• Shelf-ready packaging (SRP) cases open into a tray that goes straight on the shelf.
• E-commerce: cartons ship inside mailers or shipping boxes with inserts or void fill.

Cartons designed together with their shippers save space and prevent crushed corners.

Worked example: a three-SKU supplement launch

A supplement brand launches three products in 60-count bottles.

1. Size standardization: one carton size (2.5 × 2.5 × 4.75 in) fits all three bottles, so one die serves every SKU.
2. Board: 18pt SBS.
3. Print: CMYK plus one Pantone brand color; each SKU has its own accent color.
4. Finish: matte aqueous coating with spot UV product names.
5. Information: Supplement Facts on the back panel, sized at the start of design.
6. Ordering: all three printed in one run, sharing setup.

See supplement boxes.

Special carton constructions

Beyond the standard tuck and auto-lock styles, folding cartons can include:

• Tear strips for easy, tamper-evident opening
• Dispenser panels that tear away to dispense sachets or tea bags
• Hang tabs for peg display
• Windows with or without film
• Double-wall panels for extra stiffness on premium cartons
• Integrated inserts folded from the same blank to hold bottles or jars
• Reclosable tabs for products used over time

Each adds a little complexity to the die and gluing, so ask for them in your quote and we will confirm the structure and cost.

Cartons and cartoning machines

Brands that pack at volume often move from hand packing to semi-automatic or automatic cartoning. Plan cartons with the machine in mind:

• Choose a style the machine supports (often straight tuck, reverse tuck or seal end).
• Keep tolerances tight and consistent.
• Ask for pre-broken folds so cartons open reliably.
• Specify bundle counts and case packing to match the machine's magazine.
• Run a trial batch before a large order.

Folding cartons in one paragraph

Folding cartons are printed paperboard boxes cut from a single sheet and folded into shape, the standard packaging for retail products. Choose SBS for premium print, kraft for a natural look and CRB for economical high-volume lines; size them snugly around the product; pick a tuck end for light items and an auto-lock bottom for heavier ones; and add one finish that supports your brand. Ship them flat, store them dry, and pack them in a corrugated outer for distribution.

A brief history of the folding carton

The folding carton is younger than most people assume. For much of the nineteenth century, retail goods were sold loose, in bags or in heavy set-up boxes assembled by hand. The modern folding carton became practical when printers learned to cut and crease paperboard in a single press stroke, a technique credited to a happy accident in a Brooklyn paper-bag factory in the 1870s when a misaligned rule cut and creased a stack of bags at once. Pre-cut, pre-creased blanks could be shipped flat and folded where products were packed, which made branded packaging affordable for mass-market goods. Breakfast cereals, crackers, soap and medicines quickly moved into printed cartons, and the shelf as we know it was born.

The principles have not changed: a flat, printed, die-cut blank that folds into a box at the point of packing. What has changed is precision and choice. Modern presses register color to fractions of a millimeter, digital printing makes short runs economical, and finishing equipment can add foil, embossing and spot UV inline. That is why a growing brand can now order a few hundred cartons that look as polished as a global brand's.

How to brief a carton project

A clear brief saves rounds of revisions. Include:

• The product: dimensions, weight, closure type (pump, dropper, cap), and a photo
• The channel: retail shelf, peg, e-commerce, gift, or all of these
• The look: references you like and dislike, brand colors with Pantone numbers
• The must-haves: required information, barcode, claims, logos of certifications you legitimately hold
• The budget and quantity range: even a rough figure helps us recommend board and finishes
• The timing: launch date, and whether a sample is needed before the order

With that, we can recommend structure, board, print and finish in one quote and send a dieline for your exact size.
