Custom Triangle Boxes
Custom triangle boxes from 100 — triangular prism cartons with tuck ends, for chocolate bars, sandwich wedges, pencils, candles and gifts. Three printed faces, a shape that is stiffer than a square box of the same board, and a shelf pack that stacks head to tail.

Products that suit the shape
| Chocolate and nougat bars | The classic; a long triangle bar in a matching box |
|---|---|
| Sandwich wedges | A diagonal-cut sandwich in a window triangle |
| Pencils, pens, brushes | Long thin items; the triangle stops rolling |
| Gifts and favors | Small items with a ribbon or a hang tab |
Prism or pyramid
A prism is long, with two triangular ends. A pyramid rises to a point from a square or triangular base, and suits favors and small gifts rather than products. We make both; the prism is the practical one for retail. For other geometric shapes, see our hexagon boxes for gifts and retail.
Stacking head to tail
- Triangle boxes pack in a case point up and point down, alternating.
- Two alternating boxes make a rectangle, so no case space is lost.
- On a shelf, a row of points up reads as a display.
- A tray or a display carton holds a row upright at a till.
Ends, windows and print
The ends close with triangular tuck flaps, or one end is glued and one tucks for a faster pack. A window on one face shows a sandwich or a bar. Each of the three faces is a full panel for print: the brand on one, the product on the next, ingredients and barcode on the third. Kraft suits food and natural products; SBS takes full color and foil.
Food in direct contact needs a food-safe board or a liner. Say what goes inside.

Boards and films we build triangle 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.
280–350gsmMetalized 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: triangle 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 triangle 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 products go in triangle boxes?
Chocolate bars, sandwich wedges, pencils and pens, candles and small gifts.
Are triangle boxes strong?
Yes. The triangle shape resists crushing and twisting better than a square box in the same board.
How do triangle boxes stack?
Alternating point up and point down, which fills a rectangular case with no wasted space.
Can a triangle box have a window?
Yes, on one face, common for sandwich wedges.
Are they food safe?
With food-safe board or a liner, yes. Tell us what goes inside.
What is the difference between a prism and a pyramid box?
A prism is long with two triangular ends. A pyramid rises to a point and suits favors.
Can all three faces be printed?
Yes, each face is a full panel. Most designs use one for brand, one for product and one for details.
How do triangle boxes arrive?
Glued on the side seam and flat; the triangular ends fold at packing.
Can you add a hang tab?
Yes, on one end, for peg display.
Do you make display trays for them?
Yes, a tray that holds a row upright at the counter.
What is the minimum order for triangle boxes?
100 boxes per size. Counter display trays are quoted as a separate item.
How long do triangle boxes take?
Windows and food-safe liners add steps to a plain printed prism. We give a date with the quote.
