Sizes and the stack height
The lid height is the decision: a tall stack in a low lid is squashed shut. Send the burger as it is served, and we size the lid to it.
| Slider | About 90 × 90 × 60 mm |
|---|---|
| Single | About 110 × 110 × 70 mm; the standard |
| Double or loaded | About 130 × 130 × 90–100 mm; a deeper lid |
| Burger and fries | A wider clamshell with a divider for the side |
The hinge and the lock
- A scored hinge along the back, on board that folds a thousand times without cracking.
- A tab on the lid that locks into a slot on the base — firm enough for a bag, opened with a thumb.
- Vents in the lid or the sides, so steam escapes and the bun stays firm.
- A base with locked corners that carries a wet burger flat.
Board that takes grease and heat
Grease-resistant boxboard or E flute with a liner, 18–24pt by size, the resistance in the sheet and no PFAS. Food-safe inks outside; the inside plain. A bagasse clamshell holds heat better and composts; a board clamshell prints in full color and ships flat. Our bagasse burger boxes molded from sugarcane are the alternative.
Vents are placed away from the print and from the base, so the box vents without leaking.
Print for a counter stack
Clamshells are stacked flat behind a counter and pulled from a delivery bag. A color and the brand on the lid, a message inside the lid, a tick-box for the build — one or two colors on kraft or full color on white. The inside lid is what the customer reads first.
Runs, cases and the line
Clamshells ship flat in cases of 200 to 500 and fold at the counter in a second. A hundred is an event; a case a day is a busy counter. The die per size and the plates are kept.

Boards and films we build burger clamshell boxes on
A folding carton is one sheet of board, so the board is the product. These are the stocks we run for cartons, what each is good at, and where it lets you down.
Natural kraft
Unbleached folding board. Warm, hides marks, costs least. Mutes color — one or two flat colors print well, photographs do not.
250–350gsm sleeves; 14–24pt cartonsWhite SBS
Solid bleached sulfate: bright, coated, the retail carton standard. Takes accurate color and every finish. Shows scuffs sooner than kraft.
14–24ptWhite lined chipboard
A recycled gray core under a white printing face. Cheaper than SBS and slightly duller; the back of the sheet stays gray.
16–24ptKraft-look coated
A kraft face over a coated inner. The natural look with a barrier behind it — the answer where oil, grease or moisture would mark plain kraft.
14–20ptRecycled-content board
Post-consumer fiber with a gray-brown cast. Right for outers and inner components; poor for bright whites and photography.
16–22ptMicro-flute E and F
A fine corrugated layer where a carton needs structure it cannot get from board — a large panel, a heavy product, a box that ships alone.
E 1.5 mm; F 0.8 mmUncoated and textured
No clay coat, or a linen or laid grain. Print reads softer and warmer; a deboss goes deeper. Photographs do not sit well on it.
280–350gsmMetallised and pearlescent
A metallic or pearl face for a shelf that needs to catch light. Costly, and it fights a photograph — a mark or a pattern suits it better.
16–20ptNot sure which? Say what goes in it and where it is sold — the material follows from that. Our notes on recycled, recyclable and compostable cover which claims each stock can honestly carry.
- 01
Send what you have
A dimension, a photograph beside a ruler, or the product itself. No technical drawing needed — that part is ours.
- 02
We quote and draw
A price, a dieline and a date come back together. If a different build would suit the product better, that is in the reply too.
- 03
Approve the dieline
The flat drawing is yours to check: which panel is the front, where the folds fall, how deep the cavity really is.
- 04
Artwork on the dieline
You place your design on the flat we sent, or we place it for you, and you see a proof before anything goes to press.
- 05
A sample if you want one
A plain unprinted sample at the finished size shows fit and construction — the things a drawing cannot.
- 06
Cut, printed, shipped
The die is cut once and kept, so every reorder skips the tooling and goes straight to press at a lower unit price.
Format
Vector PDF or AI where possible. Raster artwork at 300dpi at final size, in CMYK.
Bleed
3 mm past every trim line, so a fraction of drift on the cutter never leaves a white edge.
Safe area
Keep type and anything important 4 mm inside the cut and away from every fold.
Color
Convert to CMYK before sending. Uncoated stock prints lighter; a spot color is the only exact match.
Fonts
Outline them or supply the files. A missing font substitutes silently and the proof will not match.
Barcodes
On a light, matte, unvarnished patch with the quiet zone clear — a code on gloss fails the scanner.
Not set up that way? Send it anyway — fixing a file is a short conversation, and we check every one before press. Our guide to preparing print files covers each point.
Every finish here is a decision about light on a shelf, not about luxury.
Matte lamination
Reads considered, hides marks, takes a ballpoint.
Gloss lamination
Lifts color; glares under shop lighting.
Soft-touch
Velvet in the hand; shows fingerprints in a bag.
Hot foil
Real metal leaf — the most reliable premium signal.
Emboss / deboss
Shape with no ink; works in the dark.
Spot UV
Gloss shapes on a matte field.
Uncoated kraft
Warm, natural, mutes color.
Textured stock
Texture in the paper; cannot scuff off.
Not sure which suits the shelf it sells from? Say where the product is sold and we suggest one — our notes on specialty finishes show them on real boxes.
Sizing a folding carton so the die comes out right: burger clamshell boxes
Measure the product, not the box it is in now. A carton is built around what has to fit inside it, assembled — cap on, lid fitted, folded if it folds — at its widest point in each direction. Send those three numbers and say which is which.
- Length x width x height
- Internal, always. External dimensions include the board and are what the carrier measures, not what the product needs.
- Clearance
- 2–3 mm a side for a snug fit; more where an insert or void fill goes in. A carton cut exactly to the product is slow to pack and transmits every knock.
- Board thickness
- Heavier board takes internal space from the product. It matters most on small boxes, where four walls of 24pt is a real share of the cavity.
- Varies between batches?
- Glass, textiles, molded parts and cured soap all do. Measure several and build to the largest.
- Cutting tolerance
- Plus or minus 1 mm on folding board. Confirmed on a plain sample before the run.
- Units
- Metric or imperial, as long as you say which. Mixing them in one spec is where mistakes happen.
Not sure your numbers are right? Send the product dimensions rather than the box dimensions and we work the box out — the full method is in our guide to measuring for a box.

Frequently asked questions
Got a question about burger clamshell boxes? The answers below cover what we get asked most. If yours is not here, send it with a brief, message us on WhatsApp, or call +1 503-461-4788 — we reply the same working day.
What sizes do you make?
Slider, single, double and burger-and-fries, with the lid height set from the burger as it is served.
Will the hinge tear?
Not on a properly scored hinge in the right board. It is designed to fold many times without cracking.
Does the lock hold in a delivery bag?
Yes, a tab into a slot, firm enough for a bag and opened with a thumb.
Will the bun go soggy?
Not with vents placed to let steam out and a grease-resistant board that does not sweat.
Is it PFAS-free?
Yes.
What is the minimum order?
100 boxes.
Does it ship flat?
Yes, in cases of 200 to 500, folding at the counter in a second.
Can I print inside the lid?
Yes, a message or a tick-box for the build, which is what the customer reads first.
Board or bagasse?
Board prints full color and ships flat; bagasse holds heat better and composts. Both are available.

Yes, a wider clamshell with a divider.
Are the inks food safe?
Yes, with a plain interior.
Do you ship outside the US?
Yes, to the United States, United Kingdom, Canada and Australia, quoted in the delivery currency.
