Slotted partitions or die-cut cells
| Slotted cross partition | Kraft strips slotted into a grid; no glue; any cell count; drops into the box |
|---|---|
| Die-cut cell insert | One folded kraft sheet with cut-outs; shaped to round or odd items |
| Platform with cells | A raised board with holes for jars or bottles; the items stand in it |
| Layer pad | A flat kraft sheet between layers |
Cut to the box and the items
A divider is sized to the internal box dimensions less 1 mm and to full depth, so it braces the walls as well as separating the contents. Cells are sized to the item plus 2–3 mm. Send the box and the items, or the box dimensions and a photograph beside a ruler, and the layout is drawn. Our corrugated dividers for shipping cases are the heavier version for transit.
Kraft board weights
- 300–400 gsm kraft board for small gift boxes and light items.
- 500–600 gsm or 18–20pt kraft boxboard for jars, candles and sets.
- E flute kraft for heavy items and shipping boxes.
- Food-grade kraft where the divider touches unwrapped food.
Printed kraft
A kraft divider takes one color — a logo on the top edge, a number in each cell, a pattern on a platform — printed before cutting. White ink on kraft is soft and reads well; black is crisp; a brand color prints warm. Most kraft dividers are plain, because plain kraft is the look.
A divider in a printed white box reads as a contrast; in a kraft box it disappears. Both are intentional; say which.
Gift boxes, subscription boxes and sets
Candle sets, jam and preserve boxes, skincare sets, tea selections, subscription boxes with a changing mix — the kraft divider is what turns loose items into a set. It ships flat, assembles in seconds, and is quoted with the box or on its own to fit a box you already have.

On every job
- Print process
- Flexo in one to four colors straight onto the liner; litho-lamination where the box needs full color or a photograph.
- Color
- Flat colors on kraft. Full color needs a white top liner or a laminated sheet, because brown shifts every color warm.
- Tolerance
- Cutting plus or minus 1.5 mm. The flute compresses, so corrugated runs wider than folding board.
- Tooling
- No die on a regular slotted box, which is cut on a slotter. Die-cut mailers and trays need one, made once and kept.
- Food contact
- Food-grade liners and a vented build where the box carries hot food.
- Sustainability
- High recycled content through liners and flute as standard, and the box recycles whole if it is sealed with paper tape.
- 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 kraft box dividers on
Corrugated is a fluted sheet glued between two liners, and the flute decides nearly everything: how it prints, how it dents, how high it stacks. These are the grades we run.
E flute
About 1.5 mm. Prints well and folds crisply; dents under a stack. Retail boxes, mailers and light shippers.
1.5 mm, single wallB flute
About 3 mm. The working default for parcels — takes print reasonably and stacks reasonably. Most shipping boxes are B.
3 mm, single wallC flute
About 4 mm. More cushioning than B, slightly less stacking strength per weight. Common on grocery and produce cases.
4 mm, single wallBC double wall
B and C glued together, about 7 mm. Heavy or fragile goods, pallet stacking, anything over roughly 15 kg.
7 mm, double wallKraft liner
Brown, strong, absorbent. One or two flat colors flexo print well on it; photographs drink into the brown and go muddy.
Outer and inner linerWhite top liner
A bleached outer liner for full-color print on corrugated. Costs more and marks more easily than kraft.
Outer liner onlyRecycled-content corrugated
High post-consumer fiber through liners and flute. The default for shippers; a slightly greyer brown and no loss of strength at grade.
All flutesCoated and water-resistant
A coating or a wax-free barrier liner for damp stores and cold chains. Check the recycling stream before printing a claim on it.
B and C fluteNot 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.
Corrugated takes fewer finishes than folding board, and the ones it takes it takes well.
Flexo on kraft
One or two flat colors straight onto brown. Cheap, fast, honest.
Litho-lamination
An offset sheet glued to the flute: full color and photographs on a shipper.
Aqueous varnish
Scuff resistance with no film, so the box still recycles whole.
White top print
Full color flexo on a bleached liner; brighter, and it marks more easily.
Inside print
A second pass on the inner liner — the panel a customer sees first.
Printed tape seal
The brand applied at the last moment, on paper tape that recycles with the box.
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 corrugated box against the carrier, not the catalog: kraft box dividers
Corrugated is cut to your internal size, so the box goes round the product rather than the product going into a stock size. That is where the money is: a box 20 mm smaller each way is often a whole postage band cheaper.
- Internal dimensions
- Length, width and depth of the space you need. Board thickness is added outside that, and the flute is thicker than people expect.
- Clearance and void fill
- 5–10 mm a side for a rigid product. Size it properly and you need no void fill at all, which is cheaper and better received.
- Stacking
- Tell us how high the boxes stack on a pallet or a shelf. Edge crush grade is specified from that, not guessed.
- Weight
- The contents weight sets the flute and the liner grade. Over about 15 kg we move to double wall.
- Score allowance
- Corrugated needs more room at the folds than boxboard. The dieline accounts for it; a box drawn from flat dimensions comes out tight.
- Cutting tolerance
- Plus or minus 1.5 mm on corrugated, wider than folding board because the flute compresses.
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 kraft box dividers? 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.
Can you make a divider for a box I already have?
Yes. Send the internal dimensions and the items, or the box itself, and the divider is cut to fit.
Slotted or die-cut?
Slotted for a grid of similar items, no glue; die-cut for round or odd shapes that need a shaped cell.
Is it food safe?
In food-grade kraft, yes, where the divider touches unwrapped food.
Can it be printed?
Yes, one color — white, black or a brand color — on the top edge or in the cells. Most are plain.
What is the minimum order?
100 dividers.
Does it ship flat?
Yes. Slotted partitions cross together by hand; die-cut inserts fold in.
Will it hold a candle jar?
Yes, on 500–600 gsm kraft or a kraft boxboard with a cell sized to the jar plus 2–3 mm.
Does it strengthen the box?
Yes, cut to full depth it braces the walls as well as separating the contents.
Can it hold a changing mix of items?
Yes, with a few standard cell sizes so a subscription box changes contents without changing the divider.
Kraft in a white box?
It reads as a contrast. In a kraft box it disappears. Either is a choice.
Can I have a platform with holes for bottles?
Yes, a raised board with holes so bottles stand in it.
Do you ship outside the US?
Yes, to the United States, United Kingdom, Canada and Australia, quoted in the delivery currency.
