Keeping the air off it
Plain paperboard breathes, and a bath bomb in a plain carton on a humid shelf will start to react through the box. The reliable answer is a barrier between bomb and board: a shrink-wrap or a compostable cellulose film around the bomb, with the carton as the printed outer. Where brands want the bomb loose in the box, a poly-coated or wax-laminated board slows the moisture and a tight tuck helps, but it does not seal.
We are direct about this because it is the most common complaint in the category: the bomb looked perfect leaving the workshop and arrived with a white bloom on it.
| Shrink film + carton | Full moisture barrier, bomb visible through a window, most common |
|---|---|
| Cellulose film + kraft carton | Compostable barrier, matte look, slightly higher cost |
| Bare bomb in coated carton | Slowed, not sealed; fine for fast-turnover local retail |
Holding a sphere still
The cradle hole is the critical dimension. Cut to the bomb diameter and the bomb drops through; cut 15 percent under and it sits proud with the color showing.
- A die-cut cradle with a circular hole slightly under the bomb diameter, so it sits in the ring and cannot roll.
- Corrugated or paperboard dividers for sets of four or six, each cell a cradle.
- A tuck-in platform with a domed cut-out for flat-bottomed bombs.
- A tray-and-sleeve build where the tray is the cradle and the sleeve carries the print.
The window question
A bath bomb is bought on color and the window is how the color sells. Cut it in the lid over a cradled bomb and the bomb is framed; leave the window open and humidity has a way in; cover it with PET film and it is closed. We recommend the film whenever the bomb is not separately wrapped, and it is the same construction we use on windowed candle boxes for glass jars.
Bath bombs shed glitter and pigment. A colored or kraft interior hides the dust a white one shows after a week on the shelf.
Singles, pairs, and the gift set
A single-bomb carton is a small cube, usually 2.5–3 in on a side, and runs cheaply many-up. A pair or a set of four moves to a shallow tray with dividers under a lid or a sleeve. Sets are where most of the value is, and the same tray-and-lid approach is what we build for bath salt boxes with fitted trays when a brand combines the two.
For a set that ships, a snug fit does more than any amount of cushioning — a bomb that cannot move cannot hit anything.

Boards and films we build bath bomb 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: bath bomb 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 bath bomb 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.
Will the box stop the bomb from going off in humidity?
On its own, no — paperboard breathes. A shrink or cellulose film around the bomb is the barrier; the carton is the printed outer around it. Coated board slows it but does not seal.
How do you stop the bomb rolling around?
A die-cut cradle ring cut about 15 percent under the bomb diameter, so it sits in the ring with the top showing and cannot move.
Can I have a window?
Yes, in the lid or the front, with PET film so the window does not let air in. An open window is a humidity path.
What size box for a standard bomb?
Most bombs are 2.5–2.75 in across, which gives a 3 in cube carton. Send us the actual diameter and we cut the cradle to it.
Do you make boxes for sets?
Yes, trays with cell dividers for two, four or six under a lid or a sleeve. Sets are where the value is.
Is kraft board suitable?
Yes, and it hides the glitter and pigment dust a bomb sheds. Pair it with a film wrap on the bomb for the moisture barrier.
Will the box survive shipping?
A cradled bomb in a snug carton inside a shipping box, yes. Movement is what breaks bombs, so the cradle matters more than cushioning.
Can the whole thing be compostable?
With a cellulose film wrap and an uncoated kraft carton, yes. The PET window is the part to leave out for that build.
What is the minimum order?
100 boxes. Small cubes run many-up on a sheet, so the tooling cost per box is low.
Do you supply the shrink film?
We can supply shrink bands sized to your bomb. Most makers already have a heat gun and wrap in-house.
How long does production take?
It depends on the insert and the quantity. We give a date with the quote rather than a number before we have seen the spec.
Will you send a sample?
A white sample with the cradle cut to your diameter, so the fit is confirmed before print.
