How the corner locks
Each corner has a flap with a shaped tab that folds in and pushes through a slot in the adjacent wall. The tab expands behind the slot and holds. Four pushes and the tray is square, with the tabs on the outside or the inside as the design chooses. It comes apart the same way, which matters to nobody at a counter and to everybody at the recycling bin.
Foods that live in a foot lock tray
| Bakery | Pastries, doughnuts, brownies; a plain or printed tray under a sleeve or a bag |
|---|---|
| Sandwiches and wraps | A shallow tray; a sleeve over it |
| Fries, wings, loaded dishes | A deeper grease-resistant tray |
| Produce and eggs | A vented tray; E flute |
| Gift and retail sets | A tray inside a sleeve or a lid |
Board for the food
Our tray sleeve boxes with a printed band put a sleeve over this tray for a branded pack.
- Grease-resistant boxboard, 18–24pt, PFAS-free, for anything oily or hot.
- Plain food-grade board for dry bakery goods.
- E flute for produce, heavy trays and anything stacked.
- Kraft or white; printed outside, plain inside.
Sizing and stacking
A tray is sized to the portion plus a few millimeters and to the sleeve or lid that goes over it. Tapered walls let empty trays nest and full trays stack with a lid or a sheet between. Depth from 25 mm for a sandwich to 80 mm for a loaded dish; a rolled rim on deep trays for stiffness.
Foot lock tabs on the outside are stronger; on the inside they are cleaner-looking. Say which.
Counters that fold hundreds a day
A bakery or a sandwich counter folds trays as it serves. The foot lock is the fastest glue-free tray there is, and it is what most delis are already using unprinted. Printing it is a small step; the die is kept and the trays ship in bundles of 100 or 250.

On every job
- Print process
- Flexo in one to six colors, printed on the outer face only and before any lining goes on.
- Color
- Food-safe inks throughout. Kraft mutes color; a white board or liner is needed for anything photographic.
- Tolerance
- Cutting plus or minus 1 mm, and fit confirmed by filling a plain sample from your own kitchen or line.
- Tooling
- A cutting die per size, kept. Molded pulp needs a tool per shape, which is a longer lead and a larger one-off.
- Food contact
- Every board food-contact grade, with grease resistance built into the sheet and never a PFAS treatment.
- Sustainability
- Aqueous linings and unlined boards repulp with ordinary paper. PE-lined cups need cup collection, and we say which you have.
- Artwork
- Vector PDF or AI, 3 mm bleed, 4 mm safe area, fonts outlined. We check every file and send a proof before press.
- Dieline
- Supplied free with the quote, before you commit. Yours whether or not you order.
- Sample
- A plain unprinted sample at the finished size on request, for fit and construction.
- Reorders
- Skip the tooling and go straight to press at a lower unit price.
- Lead time
- Quoted with the price against your fill date rather than promised before we have seen the spec.
- Markets
- United States, United Kingdom, Canada, Australia — priced in the delivery currency, freight included.
Boards and films we build foot lock trays on
Food packaging is chosen for what the food does to it: grease, steam, heat and time. Every board here is food-contact grade, and none of them uses a PFAS treatment for grease resistance.
Food-grade virgin board
Bleached board made for direct food contact. Clean, bright, no recycled fiber and no mineral-oil risk from recovered paper.
14–24ptGrease-resistant board
Resistance built into the sheet rather than sprayed on. Holds fries, pastry and butter without darkening. PFAS-free.
16–24ptPE-lined cupstock
Board with a polyethylene film for hot and cold liquid. Microwave-safe for reheating; recycled only where cup collection exists.
260–350gsmAqueous-lined cupstock
A water-based lining instead of PE. Repulpable in ordinary paper recycling in more places, and compostable; a slightly shorter hold time.
260–320gsmGreaseproof and glassine
Dense, calendered paper that resists fat through the fiber. Wraps, liners and interleaves; breathable, so pastry stays crisp.
30–55gsmFood-grade corrugated
E and B flute with a food-contact liner, vented where steam has to leave. Pizza, catering and anything hot and heavy.
E and B fluteMolded pulp and bagasse
Fiber pressed into a shape. Holds heat, resists grease with no lining, composts, and takes only an embossed or one-color mark.
Molded to shapeRecycled board
Post-consumer fiber. Used for outers, sleeves and anything that does not touch food directly — not for direct contact.
Non-contact onlyNot 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.
Food finishes are limited by what may touch food, and that is the point.
Food-safe inks
Printed on the outer face only. Every food pack we make uses them, laminated or not.
Uncoated kraft
No coating at all. Breathable, so pastry stays crisp, and it takes one or two colors.
Aqueous varnish
Scuff resistance without a plastic film, so the pack still repulps.
Molded emboss
A logo pressed into pulp or bagasse. No ink, nothing to rub off, and it survives grease.
Grease-resistant face
Not a finish you can see. It is in the sheet, it is PFAS-free, and it is why the print stays clean.
Matte lamination
Available on outers and sleeves that never touch food — a cake box lid, a carrier, a gift sleeve.
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 food packaging around a portion, hot: foot lock trays
Food is sized by serving, not by dimensions, and it is served hot, heaped and in a hurry. Send us the portion — or better, the box you use now with the food in it — and we size to how it is actually filled.
- Portion, heaped
- Fries, popcorn and salad are served above the rim. A box sized to a level fill looks mean and spills in a bag.
- Lid clearance
- Enough that a loaded burger or a topped cake does not touch the lid. This is the single most common complaint about a food box.
- Venting
- Hot food steams. Vents in the lid keep pastry and fries crisp; a sealed box is right only for cold food.
- Grease path
- Where the fat sits decides the board. Say if the food is fried, buttered or sauced, and whether it is held for minutes or an hour.
- Stacking in a bag
- Delivery boxes are stacked five high on a bike. The lid has to hold the box above it off the food below.
- Sample fill
- A plain box filled from your kitchen settles the size in one try, and we send one before the run.
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.

A tab at each corner pushes through a slot in the next wall and locks. Four pushes, no glue.
Is it food safe?
Yes, in grease-resistant or food-grade board with food-safe inks outside and a plain inside.
Does it ship flat?
Yes, as flat blanks, which is why it takes so little space.
Can it hold oily food?
Yes, on the grease-resistant board, PFAS-free.
Can a sleeve go over it?
Yes, a printed sleeve or a lid; the tray is sized to it.
What is the minimum order?
100 trays.
Do empty trays nest?
Yes, with tapered walls. Full trays stack with a lid or a sheet between.
Tabs outside or inside?
Outside is stronger; inside is cleaner-looking. Either is available.
Can I have a vented tray for produce?
Yes, in E flute with vents.
Is it recyclable?
Yes, as paper, and it comes apart flat for the bin.
Kraft or white?
Either. Kraft for bakery and produce; white for full color.
Do you ship outside the US?
Yes, to the United States, United Kingdom, Canada and Australia, quoted in the delivery currency.
