Custom Cake Slice Boxes in Australia: The Complete Buyer's Guide

By the Custom Food Boxes Australia team. Updated 2026-09-28

Everything you need to know before ordering custom cake slice boxes, from styles and sizes to board, printing and sustainability.

This guide is for bakeries, patisseries, home bakers and café kitchens looking at custom cake slice boxes. It covers what matters most before you order, with practical examples from Australian food businesses.

Custom cake slice boxes at a glance

Custom cake slice boxes are food-grade boxes made to your size, structure and artwork instead of picked from a generic range. They are used for slices of cake, cheesecake wedges, tart slices and café takeaway desserts, and they are a staple for bakeries, patisseries, home bakers and café kitchens across Australia.

A wedge shape matches a standard slice so it doesn't slide and topple in transit. That practical detail matters because a box that fails in transit costs you the food, the customer's goodwill and often a refund. A well-made box does the opposite: it protects the product, carries your brand into homes and offices, and gives people a reason to remember where the food came from.

You can see standard sizes and options on our Cake Slice Boxes page, or browse the wider range of bakery boxes.

Where cake slice boxes work best

Most orders for cake slice boxes come from businesses packing slices of cake and cheesecake wedges, but the same box often ends up doing several jobs across a menu or product range.

  • Slices of cake: the food often travels further than you'd expect, so strength counts.
  • Cheesecake wedges: a box that photographs well brings free exposure on social media.
  • Tart slices: the box has to hold its shape from the counter to the customer's table.
  • Café takeaway desserts: presentation matters as much as protection, so the print needs to be sharp.

If your range covers more than one of these, it is usually cheaper to settle on two or three standard sizes and print them all with the same artwork than to order a different design for every item.

Common cake slice boxes structures compared

The structure of the box decides how fast it folds, how well it protects the food and how it looks when opened. These are the styles we make most often for cake slice boxes:

  • Triangle wedge box: A triangular profile matches the shape of the food, so it can't slide around.
  • Window clamshell: The lid and base are one piece joined by a hinge, which makes packing fast and closing secure.
  • Tuck end box: Flaps tuck in to close the box without glue or tape, which keeps unit cost down.

If none of these fits, we can combine features, for example adding a window to a tuck box or an insert to a lid-and-base box. Your dieline is drawn around the food, so the finished box fits properly.

Size guide for cake slice boxes

These are the sizes customers ask for most often. They are a good starting point, but every box can be made to your exact dimensions.

Popular sizeCommon use
120 x 90 x 80 mmslices of cake
150 x 100 x 90 mmcheesecake wedges

CustomAny size to suit your product

As a rule, allow 5 to 10 mm of clearance on each side of the food and more on top if it has icing, toppings or a domed shape. Too much space lets food slide around; too little crushes it or smears it on the lid.

Best materials for cake slice boxes

The right board depends on the weight of the food, how far it travels and the look you want. For cake slice boxes the usual options are:

  • SBS paperboard: Solid bleached sulphate board gives a bright white surface for sharp, full-colour print. It is the usual choice for retail cartons and bakery boxes, and is commonly specified between 300 and 400 gsm depending on the weight of the food.
  • Kraft paperboard: Unbleached kraft has a natural brown finish that suits rustic, organic and eco-minded brands. It prints best with bold one- or two-colour artwork, because the brown base shifts lighter colours.
  • Board with a display window: A die-cut window, either open or covered with clear film, lets customers see the product. A film-free cut-out keeps the box a single material, which helps recycling.

The main risk to plan for with this type of packaging is grease from butter-rich bakes and condensation from warm products. Choose the board and any inside coating with that in mind, not just the print.

How your artwork gets printed

Most cake slice boxes are printed in one of three ways, and the right one depends on your quantity and artwork.

  • Offset CMYK: sharp full-colour print for photos, gradients and detailed designs. Best value on larger runs.
  • Spot colours (Pantone): exact brand colours that stay consistent between orders. Worth it if colour matching matters to you.
  • Digital print: no plates, so it suits short runs, test designs and seasonal versions.

On kraft board, bold one- or two-colour designs usually look better than full photos, because the brown base changes how colours appear. Our CMYK vs Pantone guide explains the difference in more detail.

Making cake slice boxes more sustainable

Paperboard cake slice boxes are one of the easier food packaging items to make sustainable, because the main material is widely recycled in Australia when it is clean.

  • Choose kraft or recycled-content board where the look suits your brand.
  • Use a film-free window or no window at all, so the box stays a single material.
  • Ask for water-based barrier coatings rather than plastic laminates where grease resistance is needed.
  • If you want compostable packaging, ask for certification to AS 4736 (industrial) or AS 5810 (home composting).
  • Add clear disposal instructions, such as the Australasian Recycling Label, so customers know what to do with the box.

Most states have also phased out many single-use plastic food items, so paper-based boxes help keep you ahead of the rules. Check your state's current list, as it changes.

Frequently asked questions about cake slice boxes

Are cake slice boxes recyclable?

Paperboard boxes are widely recyclable in Australia when clean. Heavy food waste or plastic laminates can make recycling harder.

Can I order different designs in one run?

Often, yes, if they share the same size and board. Ask us about splitting artwork across one order.

How long does it take to make cake slice boxes?

Production is typically 10–15 business days after artwork approval, plus delivery time to your location.

Can you print on the inside of cake slice boxes?

Yes, we can print inside and out. Keep inside print away from direct food contact, or use a barrier coating.
