Candles combine the two things parcel networks are worst with: glass and heat. Almost every damaged candle is either a vessel that broke because it could move, or a wax surface that slumped because it got warm. Packaging can fix the first properly and manage the second.
The method
- Measure the vessel at its widest point, which on a tumbler is the rim and on a tapered jar can be the shoulder. Include the lid if it ships fitted.
- Choose a retention insert. A die cut corrugated fitment or a moulded pulp tray that grips the vessel and keeps it off the base and the walls. This does more than any amount of loose fill.
- Set the internal box size as the vessel plus the insert walls on both sides. The insert is part of the dimension, not an afterthought.
- Pick the board from the filled weight, not from the box size. Filled glass is heavy for its volume, and a multipack of three is a different board decision from a single.
- Close and label. Fragile marking helps a little, an upright orientation marking helps more, since a candle on its side with a soft wax surface is a refund.
Retail box and shipper are two boxes
A printed candle box that sells on a shelf is doing a different job from the carton that survives a parcel network. Plenty of brands use the retail box inside a plain shipper with a fitted insert. If you want a single box to do both, it has to be built to ship, which means a heavier board, a locking closure and a finish that tolerates handling. That is the same trade-off described on what SIOC packaging is.
Heat, and what to do about it
There is no board grade that stops wax softening. What you can do is manage exposure: ship faster in hot months, avoid holding parcels over a weekend in a warm hub, and tell the customer when to expect it so it is not sitting on a doorstep at midday. Choosing the production and freight lane deliberately helps here, because a rush lane using expedited production plus air freight spends less time in transit than a cost saver sea lane. Rush carries a premium of about 7 to 25% depending on the job, and that is a seasonal decision rather than a permanent one.
Multipacks and sets
Two candles loose in one box will find each other. Every multipack needs a divider between vessels, and the divider has to reach the full internal depth, not half of it. For gift sets with a candle plus a matchbox, a card and a lid, lay the set out flat first, measure the arrangement, and give the small hard items their own recess so they do not sit against the glass.
Ordering
The minimum 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 fitment cut to your exact vessel diameter is not an extra tooling line. Production is quoted per product in three lanes, rush (expedited production plus air freight), standard (air) and cost saver (sea), from about 7 business days, plus 2 to 5 for delivery. Two plants make the work, West Chicago and Guangzhou.
Send the vessel dimensions, the filled weight and whether you ship singles or multipacks with your quote request, and say which months are your peak so the lane can be planned around the heat. To order candle packaging directly, custom candle boxes is the product page.
