Where the six corners are
A four-corner tray glues at each corner of the base. A six-corner tray adds two more glue points on the long walls, which lets the walls fold inward flat and spring back square. The result is a tray with a rigid rim that holds its shape with weight in it, and a flat pack that stores in a fraction of the space of an assembled tray.
Products that use it
| Bakery trays and cake bases | With a separate lid or a clear dome; food-grade board |
|---|---|
| Fruit and produce trays | E flute; vented; stacking |
| Retail trays and gift-set bases | Boxboard; a sleeve or a lid over it |
| Shelf-ready trays | The tray part of a retail-ready case |
| Catering platters | Large E flute trays with a lid |
Board and the rim
Our tuck boxes in every style cover the closed cartons the six-corner tray sits alongside.
- 18–24pt boxboard for retail and bakery trays.
- E flute for produce, catering and anything over a kilogram.
- A rolled or doubled rim on deeper trays for stiffness.
- Food-grade and grease-resistant board where the product touches the tray.
Lids, sleeves and domes
A six-corner tray is open. It takes a separate six-corner lid, a printed sleeve that slides over, a clear PET dome for a cake, or a film overwrap on a line. The lid is a second six-corner tray a little larger, and the pair stack. Each is quoted with the tray.
The pop-open works because the corners are glued at the factory. The tray cannot be shipped as a flat blank for gluing on site.
Print on a tray
The outside walls carry the brand; the inside is plain or printed away from the food. A tray under a clear dome is printed on the inside base too, because that is what is seen. Full color on coated board or one color on kraft.

Boards and films we build regular six corner 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: regular six corner 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 regular six corner 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.
How does a six-corner box open?
It arrives flat with the corners glued. Squeeze the long sides and it pops open square with the walls locked.
What is the difference from a four-corner tray?
Two extra glue points on the long walls, which let the tray fold flat and spring back square. A four-corner tray is glued open.
Does it come with a lid?
On request: a six-corner lid, a sleeve, a clear dome or an overwrap, quoted with the tray.
Is it food safe?
In food-grade and grease-resistant board, yes, with food-safe inks and a plain interior.
What is the minimum order?
100 trays.
Can it hold weight?
Yes, on E flute with a doubled rim, for produce and catering.
Can the inside be printed?
Yes, the inside base under a clear dome, where it is seen.
Does it stack?
Assembled trays stack; with a matching lid, the pair stacks.
Can I have it as a flat blank to glue myself?
No. The pop-open depends on factory gluing.
What sizes are possible?
From a small gift-set base to a large catering platter. Send the product and we size the tray.
Kraft or white?
Kraft with one color for bakery and produce; white for full color retail.
Do you ship outside the US?
Yes, to the United States, United Kingdom, Canada and Australia, quoted in the delivery currency.
