Square Soap Boxes

Square soap boxes solve a fit problem that long cartons have with square bars and round pucks. A round 3 in puck is 76 mm across, so a 4 oz bar carton at 64 mm wide cannot take it.

We size custom square soap boxes from your soap plus 3 mm in length and width and 2 mm in height. Full color square soap packaging runs on 300 to 350 GSM SBS or 350 GSM kraft. A square soap box with window uses 150 to 250 micron PET film or an open aperture that lets a bar breathe.

The Customized Boxes is a direct packaging manufacturer in Neptune, New Jersey with production in house. You approve a dieline and can test a plain sample before the full run. We cut square soap boxes to the bar or puck you make in SBS or kraft board, and the minimum is 100 boxes per size and design.

Which Soaps Fit in Square Soap Boxes?

Square bars, round pucks and small square guest bars all fit square soap boxes, because each one is as wide as it is long.

Square box sizes for three soap shapes, soap plus 3 mm, 3 mm and 2 mm
Soap Soap size Inside box size
Square bar, 2.5 x 2.5 x 1.25 in 64 x 64 x 32 mm 67 x 67 x 34 mm
Round 3 in puck 76 mm across x 25 mm 79 x 79 x 27 mm
Small square guest bar 51 x 51 x 25 mm 54 x 54 x 27 mm

A round puck sits in a square box with four small corner gaps that let your fingers lift it out. That equal footprint is also what makes the box so easy to stack and display.

Why Do Square Soap Boxes Stack and Display Well?

Square soap boxes stack and display well because all four sides are the same width and the lid is flat.

Twelve boxes at 67 mm square sit in a 4 by 3 tray of 268 by 201 mm with no gaps between them. A tidy stack still needs a face that shows the soap and a back that carries the label.

How Do You Lay Out the Window and Label on Custom Square Soap Boxes?

Put the window on the face and the label panel on the back, because a square box has only one large face on each side. A round stamped puck reads best through a round window of 60 mm cut into a 79 mm face.

That size leaves about 9 mm of board on each side and clears the 6 mm edge rule we use on soap boxes with window.

A moisturizing or scent claim makes the bar a cosmetic, so the back panel lists ingredients in descending order. A bar that meets all three parts of 21 CFR 701.20 counts as true soap and answers to the CPSC instead. With both panels planned you can pick the lid that keeps the box square.

Which Lid Styles Keep a Square Soap Box Square?

A tuck end and a two piece lid and base both keep the box square, and a pillow box does not. A tuck end folds from one flat sheet of board and costs the least per box.

A two piece box in rigid greyboard lifts off like a cap and suits a single bar sold as a gift. A pillow box bulges into two curved faces, so it neither stacks nor shows a flat window. Sets of square bars move to soap gift packaging with a cavity for each bar, and single boxes are ready to order.

Square soap box questions buyers ask before ordering

Send us your bar or puck size if your question is not answered below.

What is the minimum order for square soap boxes?

The minimum is 100 boxes per size and per design. A square bar box and a puck box are two sizes and count separately. It comes down on rigid, corrugated and larger sizes.

Can a round soap bar go in a square box?

Yes. A round 3 in puck of 76 mm fits a square box 79 by 79 by 27 mm inside.

Can custom square soap boxes have a round window?

Yes. A 60 mm round window on a 79 mm face keeps about 9 mm of board on each side.

Why is a pillow box not used as a square soap box?

A pillow box bulges into two curved faces, so it cannot hold a square shape or stack flat. Use a tuck end or a two piece lid and base instead.
