The most common mistake on a lotion carton is starting from the fill volume. Fill tells you how much product is in the bottle, not how much space the bottle takes. The same fill appears in a tall slim cylinder, a squat oval and a wide tottle, and those three want three different cartons. Start from the bottle.
What the fill callout does and does not tell you
Retail fills cluster around a handful of figures, which is useful for planning a range but not for cutting a die:
- 1.7 fl oz, about 50 ml, travel and trial
- 4 fl oz, about 118 ml, small retail
- 8 fl oz, about 237 ml, the common shelf size
- 16 fl oz, about 473 ml, value and salon size
Those conversions come from the fluid ounce itself, at about 29.57 ml. None of them imply a footprint. Two 8 fl oz bottles from two moulds can differ by a large margin in diameter and height.
Measure the bottle in shipping condition
Take the bottle exactly as it will leave the filling line and measure three things.
- Height with the pump locked down. A lotion pump has a locked transport position and an extended dispensing position. The carton is sized to the locked height. If you size to the extended height the box is too tall and the bottle rattles.
- Width at the widest point. That is usually the shoulder or the base, and it includes the label. A wrap label with an overlapping seam adds thickness on one side, and a pressure sensitive label on a ribbed bottle adds more.
- Depth for oval and flat bottles. Oval and tottle bottles have two different cross-section measurements, and the carton has to respect both or the bottle will turn inside it.
Clearance and whether you need an insert
A carton that is a fraction too tight scuffs the label as the bottle goes in, and at line speed that becomes a reject rate. A carton that is too loose lets the bottle tip, which crushes the end panel in transit. If your bottle is significantly narrower than it is tall, or if the carton also has to hold a pump cap and a leaflet, a fitment stops the movement. Our note on box inserts covers when a fitment is worth the extra material and when clearance alone is enough.
Writing the spec
State the internal dimension as length x width x depth, in that order, and say explicitly that it is internal. Then confirm the same thing back from the supplier on the written quote. Cartons are commonly quoted internal, rigid boxes are sometimes quoted external, and the entire cost of a wrong die is the cost of not asking.
Ordering and turnaround
Minimum order is 100 boxes, and pricing starts from about $0.48 per unit at bulk volumes, confirmed on your written quote. The cutting die and the printing plates are included, together with design support, US shipping and a digital proof before anything prints. That is the practical argument for measuring properly rather than settling for a close size: an exact internal fit does not cost extra to tool. Three lanes run, rush (expedited production plus air freight), standard (air) and cost saver (sea), from about 7 business days, plus 2 to 5 for delivery. Production is at West Chicago and Guangzhou.
Send the three bottle measurements with your quote request and we will come back with the internal dimension and, if it needs one, a fitment.
