Key Takeaway
A burger box has one engineering job: hold a hot, greasy product upright without going soggy or collapsing in a delivery bag. Teal Packaging is a US manufacturer producing clamshell and tuck-style burger boxes in food-grade board available by specification with documentation, with full-color print and grease-resistant coatings. Free dieline design comes with every order and volume pricing starts from about $0.44 per unit at scale. Suits restaurants, food trucks, ghost kitchens and delivery-first brands.

A burger box works when three things are right: interior height that clears the build without crushing it, vent openings that let steam escape, and a lock that stays shut in a delivery bag. A standard 4 in patty burger stacked with cheese and lettuce needs roughly 4.5 x 4.5 x 3.25 in inside. Measure your tallest build, not your menu photo.
Size the box against the assembled burger
| Build | Assembled size | Box inside size | Board |
|---|---|---|---|
| Single 4 in patty | 4 in across, 2.75 in tall | 4.5 x 4.5 x 3.25 in | E-flute or 18pt coated |
| Large 5 in patty | 5 in across, 3 in tall | 5.5 x 5.5 x 3.5 in | E-flute |
| Double stack | 5 in across, 4 in tall | 5.5 x 5.5 x 4.5 in | E-flute, reinforced lid |
| Three sliders | Three 2.5 in buns in a row | 9 x 3.5 x 2.75 in | 18pt coated board |
| Burger and fries combo | Burger plus a side well | 8 x 6 x 3.25 in | E-flute with divider |
| Kids portion | 3 in bun | 3.75 x 3.75 x 2.5 in | 18pt coated board |
Venting is the difference between crisp and soggy
A closed box traps steam, steam condenses on the lid, and the condensate drops back onto the bun. Two or four vent openings of about 0.25 in near the top of the side walls let vapor out without letting heat dump. Place them high, above the level of the patty, so grease does not run through them. If you sell fries in the same box, separate them with a divider and give the fry side its own vent, because fries release far more steam than the burger does.
Board, coatings, and who signs off
E-flute corrugated gives insulation and crush resistance for delivery. Coated paperboard at 18pt is lighter, cheaper, and better for a counter handoff where the box travels three feet. Uncoated kraft looks the part but shows grease within minutes, which is a real problem when a courier hands over a stained box. Coating and liner options change how a surface behaves against a hot, oily product, so ask what the board is coated with and let your own compliance team assess it against the requirements for your operation before any run.
Closures and how the box behaves in a bag
- A tuck lock front flap holds better than friction alone and takes about two seconds to close.
- Auto lock bottoms let staff pop the box open one handed during a rush, which matters at peak service.
- Flat, strong lids matter because delivery bags stack; a domed lid collapses under the box above it.
- Check the footprint against your delivery bag interior, commonly around 12 x 12 in, so two boxes sit side by side instead of one wasting the space.
- Corner rigidity keeps a stacked box from splaying; E-flute holds up better than 14pt board here.
Print that survives grease and handling
One or two flat spot colors on kraft or white liner is the workhorse for food service, cheap and durable. Heavy ink coverage on a hot, greasy surface can scuff and mark, so avoid large dark solids on the lid where hands grip. Keep the logo large and simple, since a burger box is seen for a few seconds at a doorstep, and put the menu item name on the front edge so a courier sorting four bags can read it without opening anything.
Where the money goes on a food service box
Three variables move a clamshell price more than anything else: board choice, print coverage, and quantity. Moving from 18pt coated board to E-flute raises material cost and lowers damage on delivery routes. Going from one spot color to full coverage adds a pass and, on a greasy surface, adds a scuff risk. Quantity is the lever with the most room in it, since the die is cut once. Price all three as separate lines rather than accepting a single number, because that is the sole way to see which choice you are paying for.
Send this with a burger box request
- The tallest assembled build you sell, measured with the lid of the bun in place.
- Whether fries or sides share the box, and whether a divider is needed.
- Daily or weekly volume, so the quantity tier is realistic.
- Delivery bag interior dimensions, if boxes must stack inside one.
- Artwork as vector files, plus the menu item name for the front edge.
Small runs let you test a menu change
Burger box runs begin at 50 pieces, with 100 on specialty rigid, which means a limited edition or a new item can be tested without buying a pallet. The die and any print plates carry a one time tooling charge divided by the quantity, so a repeat order of the same size is always cheaper per piece than the first. Large clamshell runs price toward $0.44 each on plain single color work, and additional passes move that upward.
Production lanes and timing
Both floors produce this format, the Illinois site at West Chicago and the Guangzhou site, with each order placed by construction and volume. Clamshells produced in house may be ready in 7 business days or so, while imported specialty orders take near 12 weeks. Treat both as scheduling windows, and buy in front of a seasonal menu launch rather than during it. Structural drafting is free, the press waits for an approved proof, and US delivery is included.
Test with real food before the run is bought
Order a sample pack at $19.99, credited toward whatever you order first, then run the only test that counts: build your actual burger, close the box, put it in a delivery bag, and drive it for twenty minutes. Open it and look at the bun, the lid, and the corners. If the lid is wet, add venting. If the burger has shifted, tighten the fit. If the box is stained through, change the surface.
