Custom pizza boxes are made from micro-flute or B-flute corrugated board, with a food-safe inner liner, in sizes from 26 to 50 cm depending on the pizza, and are usually printed by flexography with water-based inks. What pushes the price up most is the number of inks, print coverage, board quality and size; what brings it down most is the print run and using a standard size that avoids a custom cutting die.
Sizes of custom pizza boxes: standard and made to measure
A pizza box size is given by the internal side of the base, in centimetres, and is usually square. The most common sizes on the Spanish market fall into these ranges:
| Approximate size (internal) | For which pizza | Typical use |
|---|---|---|
| 26-28 cm | Individual or small | Individual meals, kids’ pizza, calzone portions |
| 30-33 cm | Medium | The best-selling delivery format |
| 36-40 cm | Family | Large or family pizza in traditional pizzerias |
| 45-50 cm | Extra-large or party | Events, sharing format |
| Rectangular (for example 30 x 40 cm) | Pizza by the slice, focaccia, pinsa | Deck ovens, Roman-style pizza |
Internal height is usually between 3.5 and 4.5 cm. More height allows pizzas with more toppings or stuffed crusts, but increases the air inside, which cools the pizza faster, and makes the board more expensive.
A money-saving tip: before ordering a custom box, measure your pizzas as they come out of the oven (the dough rises) and check whether they fit a standard size the printer already has a die for. One centimetre of clearance is enough; three is too much and the pizza slides around. If your size is standard, you save on the cutting die and, in many cases, the supplier already has the board in stock.
Materials: which board survives grease, steam and a 30-minute scooter ride
A pizza box has a tough job: taking a pizza straight from an oven at over 200 degrees, withstanding moisture, grease and weight, surviving stacking in the courier’s thermal bag and arriving looking good. The material decides almost everything.
- Micro-flute corrugated board (E flute): thin, around 1.5 mm, good print surface. Enough for small and medium pizzas on short deliveries. It deforms sooner under weight and moisture.
- B-flute corrugated board: around 3 mm. The most widely used in delivery. Handles stacking and steam better, and insulates a little more. Print quality is slightly lower than micro-flute because of the texture.
- B flute with a coated outer liner: the same structure, but the outer face has a coated white paper that greatly improves printing. More expensive.
- Inner liner: this is the part that touches the pizza and must be food-safe. It can be natural (brown) kraft or white. A white interior looks clean; kraft is cheaper and suits an artisan image.
On grease: standard corrugated board handles direct contact with a normal pizza well. If you sell very greasy or oily pizzas, there are inner papers with a grease-resistant treatment, and you can also put a food-safe paper disc under the pizza, which also helps the box get recycled clean. In our delivery packaging section we explain what solutions different types of restaurant use.
All board that touches the pizza must come with a declaration of compliance for food contact, and inks must be low-migration or printed on the outside only. Ask for it in writing; a printer that works for restaurants will have it ready.
Structure: ventilation, closures and base
Pizza boxes are almost always the attached-lid type (one folded piece), but some structural details change the result:
- Ventilation holes: let steam out and stop the base going soggy. They should be few and small, or the pizza cools. They usually go on the sides of the lid or the top corners.
- Corner tabs: folded inner corners (“locking tabs”) add rigidity and keep the lid off the pizza. Some systems raise the lid a few millimetres so the cheese doesn’t stick.
- Front closure: a tab that goes into a slot. If it’s too loose it opens in the delivery bag; if it’s too tight, the customer tears the box opening it. A physical sample is the only way to check.
- Flat or embossed base: some cutting dies include a raised pattern in the base that keeps the pizza slightly lifted and reduces condensation. It’s an extra not every printer offers.
- Box with slice cut-outs: creases in the lid that let it be split into individual plates. Great for marketing, and it increases the cost of the die.
If you’ll deliver in thermal bags with several boxes stacked, compression strength is what matters. Ask the supplier to confirm how many boxes with pizzas inside the bottom one can hold without caving in.
Printing: inks, coverage and what looks good on corrugated board
The vast majority of pizza boxes are printed by direct flexography on the corrugated board, with water-based inks. That shapes the design:
- One or two inks work better than four. Flexo prints flat colours well: logos, text, line illustrations. Photos and gradients come out coarse and cost more with each added colour.
- Large areas of colour look uneven. The flute shows through in solid backgrounds (the “washboard” effect). If you want a full-colour background, you need a coated liner or to accept the effect as part of the style.
- Kraft tints everything. On brown board, red turns maroon, yellow disappears and white doesn’t exist unless printed as an ink. Design with black, dark brown, white or a strong colour in mind.
- Printing the inside of the lid is possible and opens up lots of options (messages, QR codes, games), but adds a pass and the inks must be suitable for indirect food contact.
If image quality is key (a brand with product photography, for example), the alternative is to print offset on a sheet of folding boxboard and laminate it onto the corrugated board. Excellent result and a clearly higher price. For a neighbourhood pizzeria it rarely pays off; for a chain with branded packaging it may be the right call. The delivery boxes in our range cover both options.
What pushes up the price of a custom pizza box
We can’t give you a price, because it depends on your case, but we can rank what moves it, from most to least:
- Print run. Factor number one. Pizza boxes are produced on machines built for volume; with few units, machine start-up and printing plates weigh heavily on each box. Combining quarterly orders into one six-monthly order usually lowers the unit price noticeably, if you have somewhere to store them.
- Size. More centimetres means more board. A family size costs considerably more than an individual one.
- Board quality. Micro-flute kraft is the cheapest; B flute with a white coated liner and grease-resistant treatment is the most expensive.
- Number of inks. Each colour is a printing plate and a print station. Going from one to two inks is a moderate jump; from two to four, a bigger one.
- Print coverage. A small logo uses little ink; a full background uses a lot. In flexo, ink is charged for, and it shows.
- Custom cutting die. If your size isn’t standard, a die has to be made. It’s a one-off cost paid off over repeat orders.
- Inside printing and extras. Printed interior, special ventilation, slice cut-outs or an embossed base add cost.
When comparing two pizza box quotes, confirm they refer to the same internal size, the same flute, the same liner (kraft or white, coated or not), the same number of inks and the same coverage. A cheaper quote using micro-flute instead of B flute isn’t cheaper: it’s a different box, and it will arrive softer.

Frequently asked questions
Can a pizza box be recycled if it has grease stains?
The clean parts (usually the lid) go in the paper recycling bin. Parts heavily soaked in grease or with food residue don’t recycle well as paper and, depending on the municipality, should go in the organic waste bin or general waste. Using a paper disc under the pizza helps the base stay clean.
How many inks do I need for the box to look good?
For most pizzerias, one or two inks on kraft or white give a clean, recognizable result. A logo in black or a strong colour on kraft is a formula that works, is affordable and fits an artisan look. More inks only make sense if your brand calls for it.
Can I use the same box for different pizza sizes?
Only if the difference is one or two centimetres. A pizza sliding around inside a large box arrives out of place with its toppings shifted, and you’re also paying for board you don’t need. It’s usual to work with two or three sizes and keep the same design so the brand looks the same on all of them.
