Custom Soap Boxes

Sleeves and tuck cartons for soap

Most soap packaging is a sleeve or a tuck carton, both cut from one sheet of paperboard.

A sleeve is an open tube of board with one glued seam. The bar slides in from either end and the ends stay open, so the soap stays on show and can breathe.

A tuck carton is a closed box with a flap at each end. It encloses the bar completely and is cut and creased flat in the same way. Both ship flat and are assembled, or slid on, at packing. The creases are cut into the same die as the outline, so a bar-sized box needs only one tool.

• Sleeve: open ends, one glued seam
• Tuck carton: closed, flap at each end
• Both arrive flat, ready to fold

Sleeve, tuck carton or window?

The choice is about how much of the bar to show and how much to cover.

A sleeve is the lightest option and the quickest to pack, and it suits a bar that already has a wrapper or a natural finish. A tuck carton hides the soap and gives more space for text, so it suits a bar that is sold in a gift set.

A window lets the buyer see the colour and texture of the soap. An open cut-out also lets scent escape and dust in. A film-covered window keeps the soap clean, but it adds a second material and makes recycling harder.

Measuring a handmade bar

Handmade soap is not a standard size, so measure a bar after it has cured, not when it comes out of the mould.

Cold-process soap loses water as it cures and shrinks a little. A bar measured on the day it was cut will sit loose in a box built around it. Measure several finished bars and use the largest, because batches differ.

A sleeve should slide on without force but not fall off when the bar is turned over. A gap of a millimetre or so each side is a sensible starting point, and we draw it around your cured bar's measurements so you can check the fit on the dieline and digital proof. Rounded and irregular bars sit better in a sleeve than in a tight carton.

A box or a paper band?

A band uses far less material. A full sleeve or carton gives more protection and more room to print.

A belly band is a strip of paper around the middle of the bar. It holds a label and a barcode and leaves the soap on show. It gives no cover for the ends, and none for the soap's scent.

A sleeve or carton protects the corners and edges, which are what chip first, and carries more text. If the label must carry a full ingredient list, there is usually not enough room on a band.

Oils, scent and damp

Soap gives off moisture, and scented soap gives off oil. Uncoated board takes both in.

Fresh and fragrant soap can leave a faint oil mark on uncoated or recycled board, and the board may soften if it stays damp. A varnish, or a barrier coating on the inside surface, slows this. Where the box touches the soap, settle the coating before approving the board.

Uncoated and kraft board look natural and suit handmade soap, but colours print darker and duller on them. Keep artwork simple: one or two solid colours read better than fine detail. We leave room on the panels for the ingredients and any warnings your soap must carry, and lay them out on the proof.

Soap carton or rigid gift box?

A soap carton is the pick for a cured bar sold on a shelf. A rigid gift box is the pick for heavy sets and gift collections.

Paperboard does not like wet soap. A bar that is still soft, or one that sweats in humid weather, will mark the box and may stick to it. Let the soap cure fully, and keep stock somewhere dry, before it goes into board.

A carton is also not a shipping pack. Posted on its own, it arrives crushed at the corners, so for the post it travels inside a mailer. For heavy sets a rigid gift box or a corrugated box is the better format, and for a single bar a simple wrap and label can be enough.
