Essential oil packaging is a small parts problem. The bottles are short, the glass is thick, and the value density is high, which means the failure mode is not a crushed carton but a broken bottle inside an intact one. Specify the interior first. To order, see essential oil boxes.
Common bottle sizes and what they mean for the box
Amber and cobalt dropper bottles across the category are commonly filled at 5, 10, 15 and 30 ml, often with a standard neck finish so caps and reducers interchange between suppliers. Those fills are useful for planning a range. They are not dimensions: two 15 ml bottles can differ in height by more than a centimetre depending on shoulder shape. Get the drawing.
Measure it fitted, not bare
- Fit the orifice reducer, then the cap, and seat both fully.
- Measure overall height from base to the top of the cap.
- Measure body diameter at the widest point, usually just below the shoulder.
- Measure base diameter, which decides whether the bottle stands in a cavity.
- Add the insert wall caliper on each side of the cavity.
Single bottle, set, or retail display
| Format | Interior | Watch out for |
|---|---|---|
| Single bottle carton | Tight cavity or a small platform insert | Depth measured without the cap |
| Set of three to twelve | Die cut partitions or a moulded tray | Divider caliper adding up across the set |
| Rigid gift box | Foam or moulded tray in a wrapped rigid base | Board and wrap adding to the external size |
| Counter display | Tray with a printed riser | Shelf depth and the fixture spec |
The divider arithmetic
People size a six bottle box by multiplying one cavity by six and are then surprised when the box is short. Each divider between cavities has a caliper, and there are five of them in a row of six, plus the outer walls. Add them all. For partition formats, see partition boxes.
Oils, paper and finish
Essential oils attack some coatings and mark uncoated board quickly, and a leaking bottle in a carton is a returned unit. An interior that can be wiped, or a laminated outer, is worth specifying for anything that will sit in a retail display. Matte laminate is the common choice in the category, with foil or spot gloss for the brand mark.
Shipping small heavy items
A carton of glass bottles is dense, and parcel networks handle dense small boxes roughly. For direct to consumer, put the retail carton inside a corrugated mailer with an insert rather than shipping the retail carton bare. The retail carton is presentation; the shipper is protection. See insert packaging for the options.
Ordering and turnaround
Minimum order is 100 boxes, from about $0.48 per unit at bulk volumes, confirmed on your written quote. The die, the plates, design support, US shipping and a digital proof before printing are included, so a cavity cut to your exact bottle costs no more to tool than a near-standard size. We produce in West Chicago in the US and in Guangzhou in China. Three lanes are quoted per product: rush (expedited production plus air freight), standard (air) and cost saver (sea), from about 7 business days in production plus 2 to 5 days for delivery.
Send your bottle drawing, the bottle count per box and your quantity. Request a quote and we will return a cavity layout and a price.
