Printed custom cardboard box with a tuck end closure

Custom cardboard boxes are any boxes made to your size and printed with your design from paper-based board. The problem is that "cardboard" is not a material a manufacturer can quote. In the packaging industry, it can mean three very different things: thin paperboard used for retail cartons, fluted corrugated board used for mailers and shipping boxes, or dense chipboard (greyboard) used for rigid gift boxes.

Those three differ in thickness, strength, print quality and price by wide margins. Ask for "cardboard boxes" and one supplier may quote a cereal-style carton while another quotes a shipping carton. This guide translates the everyday word into the specs packaging makers use, shows you how to tell which one you need, and walks through ordering printed cardboard boxes without surprises.

Key takeaways

  • "Cardboard" covers three materials: paperboard (roughly 12 to 24 pt), corrugated (fluted, about 1.5 to 7 mm) and chipboard or greyboard (about 1.5 to 3 mm, usually wrapped in printed paper).
  • Look at the cut edge: a solid thin edge is paperboard, a wavy middle layer is corrugated, a thick dense gray edge is chipboard.
  • Pick the material by job: paperboard for shelves, corrugated for shipping, chipboard for keepsake presentation.
  • Many products need two layers, such as a paperboard retail carton inside a corrugated mailer.
  • For scale, an 18 pt straight tuck end carton at 3x2x5 in is about $0.51 each at 1,000 units, while a 2 mm rigid box at 8x6x3 in is about $4.05 at 1,000.
  • Box Sense makes all three families in-house, from a minimum of 10 boxes, with free dielines and a 3D proof.

Paperboard: the retail carton

Paperboard is what cereal, cosmetics, supplements and toothpaste come in. Solid bleached sulfate (SBS) is the bright white version with a smooth coated face; kraft paperboard is the natural brown version. Our SBS paperboard page lists the grades. It is ideal on a shelf and inside a shipper, but it is not designed to go through the parcel network on its own.

Corrugated: the shipping box

Corrugated board is what most people picture when they say cardboard box, especially the brown box on the doorstep. The arched flutes make it stiff and cushioning for its weight. Our corrugated boxes guide goes deep on flutes and grades.

Chipboard: the rigid box

Chipboard, also called greyboard, is thick and dense and does not fold. Pieces are cut, joined and wrapped in printed or textured paper to make a rigid box, the kind a phone, watch or luxury gift set comes in. The custom rigid boxes guide explains the construction, and the rigid greyboard material page covers thicknesses.

How to tell which cardboard you already have

If you are replacing a box you already use, or copying a competitor's format, you can identify the material in a couple of minutes.

  1. Find a cut edge. Look at the edge of a flap or tear a corner.
  2. Check for a wavy layer. If you see a row of arches between two flat layers, it is corrugated. Small tight waves suggest E-flute; larger ones suggest B or C-flute; two rows of waves means double wall.
  3. If the edge is solid, measure it. A thin solid edge you can bend easily by hand is paperboard. A thick, dense, gray edge that will not fold is chipboard.
  4. Look at the inside. Paperboard is often white or gray inside. Rigid boxes usually show a paper wrap folded over the edge onto the inner walls.
  5. Check how it was assembled. A glued side seam with tuck flaps is a folding carton. Locking tabs and a hinged lid suggest a corrugated mailer. Solid corners with no flaps point to a rigid box.
  6. Measure thickness if you can. Use calipers, or stack ten flat sheets and divide. It helps you compare quotes.

A quick guide to thickness units

Packaging uses different units for each material, which adds to the confusion.

UnitUsed forWhat it meansExample
Points (pt)PaperboardThousandths of an inch18 pt is 0.018 in, roughly 0.46 mm
gsmPaperboard, wrap papersGrams per square meter, a weight not a thickness12 to 24 pt SBS is roughly 250 to 450 gsm
Flute letterCorrugatedFlute size, which sets thicknessE-flute about 1.5 mm, B-flute about 3 mm
ECT or burstCorrugatedStrength grade32 ECT is a common single wall grade
MillimetersChipboardBoard thickness2 mm greyboard is a common rigid box core

Heavier gsm usually means thicker board, but two boards of the same gsm can differ in caliper depending on density and coating. When you compare quotes, compare the same unit.

Choosing the right cardboard packaging boxes for the job

Three questions settle the material for most products.

Does the box travel through a parcel carrier by itself? If yes, you need corrugated. Paperboard cartons get crushed and punctured in parcel sorting unless they are packed inside a shipper.

What does the customer need to feel? A light, well-printed carton says "retail product." A sturdy mailer says "direct-to-consumer brand." A heavy rigid box says "premium, keep me."

How heavy is the product? Light items under about a pound are fine in 18 pt paperboard. Denser items, bottles and jars often need 24 pt board or an auto-lock bottom. Heavier products and anything fragile need corrugated or an insert.

One product, three kinds of cardboard

Say you sell a scented candle in a glass jar through a website and a handful of boutiques. The boutique shelf needs an 18 pt paperboard carton with an insert that grips the jar. The online order ships that same carton inside a small corrugated mailer. And for the holiday season you add a limited gift set in a rigid box with a magnetic lid.

That is one product in all three materials, each chosen for a different job. Planning them together means the carton fits the mailer without dead space, and the artwork system stays consistent.

Box styles in each cardboard family

Once you know the material, the style decides how the box opens, closes and fills.

Paperboard styles

  • [Straight tuck end boxes](/products/straight-tuck-end-boxes): both tuck flaps on the same side, for a clean front panel.
  • Reverse tuck end: flaps on opposite sides, the most economical carton for small products.
  • [Auto lock bottom boxes](/products/auto-lock-bottom-boxes): a bottom that snaps into place when the carton is opened, for heavier contents and faster packing.
  • Sleeves, pillow boxes, gable boxes and window boxes for specific looks and uses.

Our folding carton guide compares these in depth, and the folding cartons style page shows the range.

Corrugated styles

Chipboard (rigid) styles

  • Two-piece lid and base for apparel, games and gift sets.
  • [Magnetic closure boxes](/products/magnetic-closure-boxes) that open like a book. The magnetic closure boxes guide covers them.
  • Drawer and shoulder neck boxes for jewelry and fragrance.

Printed cardboard boxes: what each material can do

Print quality varies more between materials than between print methods, so match your artwork ambitions to the board.

Printing on paperboard

Paperboard gives the sharpest, most accurate print of the three. Coated SBS reproduces photography, fine type and gradients well, and it takes every finish: matte, gloss and soft-touch lamination, foil, embossing and spot UV. If your packaging carries a lot of information in small type, such as ingredients, directions or regulatory panels, paperboard handles it best.

Printing on corrugated

E-flute corrugated prints close to paperboard with digital printing and offset laminated onto the board. Thicker flutes are rougher and suit bolder graphics. Large solid areas of dark color can show faint lines from the flutes, so patterns and white space tend to look better.

Printing on chipboard

Chipboard is not printed directly. The artwork is printed on a wrap paper, then glued around the board. That means rigid boxes get paperboard-level print quality plus access to specialty papers with linen, leather-grain or pearlescent textures.

Box Sense prints short runs, roughly 10 to 500 units, digitally, so there are no plates and full color costs no more than one color. Larger runs move to offset for the best detail and unit price. The printing and finishes page shows coatings, foils and embellishments for each material.

Tip: if you want identical artwork on a paperboard carton and a corrugated mailer, expect them to look slightly different even when printed from the same file. The board surface changes how ink sits. Approve color on a printed sample of each material, not just one.

What custom cardboard boxes cost

Because the three materials use such different amounts of board and labor, their prices sit in very different ranges. The table below compares typical specs from each family. These are indicative per-unit prices with free US shipping; sizes differ, so treat it as a view of each family's range rather than a like-for-like comparison.

FamilySpec1005001,0005,000
PaperboardStraight tuck end carton, 18 pt SBS, 3x2x5 in, full color, aqueous$1.15$0.61$0.51$0.36
PaperboardWindow box, 18 pt SBS, 4x4x4 in, full color, aqueous, window$1.66$0.89$0.74$0.53
CorrugatedMailer box, E-flute, 8x6x3 in, full color outside$2.64$1.41$1.17$0.83

ChipboardRigid box, 2 mm greyboard wrapped, 8x6x3 in, full color, matte$9.10$4.85$4.05$2.87

What moves the price within a family

  • Size: more board, more cost.
  • Board grade: thicker paperboard, heavier flute or thicker greyboard.
  • Print coverage: inside printing, extra panels, white ink on kraft.
  • Finishes: foil and embossing each carry one-time tooling of about $60, spot UV about $40.
  • Inserts: a custom insert die is about $45 one time.
  • Quantity: the biggest lever, because setup is shared across more units.

Common mistakes when ordering cardboard boxes

Most problems with a first order trace back to a vague spec. These are the ones we see most.

  • Asking for "cardboard" without a material. You receive quotes for different products and cannot compare them.
  • Giving outside dimensions. Box makers work from inside dimensions. Measure the product and say "internal."
  • Sending a retail carton through the mail alone. Paperboard is not a shipper. Plan a corrugated outer.
  • Choosing thickness by feel. A thicker board is not always stronger in the way you need. Describe the product weight and how it travels instead.
  • Designing before choosing the material. Fine type that works on SBS may blur on B-flute, and pale colors vanish on kraft.
  • Skipping the sample. A free unprinted structural sample shows fit before you pay for printing.
Watch out: a design copied from a competitor's rigid box and requested "in cardboard" usually means a much cheaper paperboard or corrugated version. That can be a smart move, but the box will not feel the same in hand. Decide whether the weight and stiffness are part of what you are paying for.

Frequently asked questions

Is cardboard the same as corrugated?

Not exactly. Corrugated board is one type of cardboard, the kind with a wavy fluted layer between two liners, used for shipping and mailer boxes. People also call thin paperboard cartons and thick chipboard rigid boxes "cardboard." When ordering, name the specific material so suppliers quote the same thing and you can compare prices fairly.

What thickness of cardboard do I need for a product box?

For a light retail product under about a pound, 18 pt paperboard is a common starting point. Heavier jars, bottles or dense items often need 24 pt board or an auto-lock bottom. If the box ships through a parcel carrier on its own, choose corrugated instead, starting with E-flute for light goods and B-flute for heavier ones.

Can printed cardboard boxes be shipped without an outer box?

Corrugated boxes such as mailers and shipping boxes are built to ship on their own. Paperboard cartons usually are not; they can be crushed or punctured in parcel sorting, so ship them inside a corrugated mailer or shipper. Rigid chipboard boxes are sturdy but their wraps scuff easily, so most brands overbox them for shipping.

How much do custom cardboard boxes cost?

It depends on which material you need. An 18 pt paperboard tuck end carton at 3x2x5 in is about $0.51 each at 1,000 units. An E-flute mailer at 8x6x3 in is about $1.17 at 1,000, and a 2 mm rigid box at 8x6x3 in is about $4.05. All include US shipping. Use the pricing page for your exact size.

What is the difference between chipboard and paperboard?

Both are solid, non-fluted boards, but at very different thicknesses. Paperboard is thin, roughly 12 to 24 pt, and folds into cartons. Chipboard, or greyboard, is thick and dense, about 1.5 to 3 mm, and does not fold. It is cut and wrapped in printed paper to make rigid boxes, which feel much heavier and more premium.

Are cardboard packaging boxes recyclable?

Paperboard cartons and corrugated boxes are widely accepted in curbside recycling. Rigid boxes are paper-based too, but magnets, ribbons and some specialty wraps can complicate recycling. To keep any box easy to recycle, choose aqueous coating over plastic lamination and paper-based inserts over foam, and check FTC guidance before printing a recycling claim.

What is the minimum order for custom cardboard boxes?

Box Sense makes custom cardboard boxes from a minimum of 10 units across paperboard, corrugated and rigid styles. Short runs are printed digitally with no plates and no die charges. Unit prices fall significantly at higher quantities, so it is worth pricing a few quantity tiers before deciding on an order size.
