What is a six corner box?
It is a one-piece tray and lid cut from a single sheet of board. Glue is applied at six points while the box is still on the folding line, so you never touch adhesive yourself.
When you lift the walls, the corners pull into shape at once. The lid stays joined along the back edge and closes with a tuck flap at the front.
That makes it one of the quickest styles to put together on a busy counter. Staff can open a whole stack during a quiet moment and keep them ready under the till. It sits in our wider range of printed retail boxes alongside tuck end and window styles.
Who orders six corner boxes?
Most enquiries come from businesses that pack by hand and need dozens of boxes ready before opening time.
The common thread is a product that is placed in from the top and lifted out the same way. Anything long, tall or narrow usually suits a different style better.
- Bakeries and cake makers boxing slices, cupcakes and whole cakes
- Clothing shops folding shirts, jumpers and scarves into a neat tray
- Gift and hamper sellers who want a lid that lifts rather than a slide-out drawer
- Chocolatiers and sweet shops filling shallow trays by layer
- Event planners preparing favour boxes for weddings and birthdays
How does it compare with other lidded styles?
A six corner box shares a family look with mailers and two piece boxes, but it behaves differently at the packing bench.
| Style | Lid | Set-up time | Best use |
|---|---|---|---|
| Six corner box | Hinged, tucks at front | A few seconds | Counter service and gift wrap stations |
| Mailer box | Hinged, locks with ears | Fold and lock by hand | Posting goods to customers |
| Two piece lid box | Separate lid | Two parts to match | Premium gifts and keepsakes |
| Tuck end box | End flaps | Fast, but opens from the end | Tall or narrow retail items |
What size six corner box do I need?
Measure the item, or the stack of items, and add a little clearance. For cakes and baked goods, 10 mm on each side is usually enough to stop icing touching the walls.
For gift sets, lay every item out on a table in the order you want and measure the whole group. Remember any card, ribbon or tissue that also has to fit.
For clothing, fold the garment the way it will be sold and measure the folded bundle. Height matters most here, because a lid that will not close flat looks careless.
Our step-by-step guide on how to measure a box properly shows where inside dimensions are taken. Give sizes in mm, cm or inches and we will work with whichever you use.
Which board works best for this style?
Folding board suits light contents such as cupcakes, chocolates and folded tops. It takes fine print well and keeps the walls slim.
E flute corrugated, about 1.5 mm thick, is the step up when the box carries a heavy cake or a filled hamper. It adds stiffness to the floor without making the box bulky.
B flute is possible for larger trays, though most six corner orders stay with folding board or E flute. If you are unsure, tell us the weight and we will suggest a board on the quote.
White folding board shows bright colours most accurately. Kraft has a warm brown base, so pale inks look softer on it and dark inks read best.
Print and finish options
The lid top is the main panel people see, so most designs put the logo there. The front tuck flap is a handy spot for a short line or a social handle.
You can choose plain, one colour, two colour or full colour CMYK, outside only or inside as well. Uncoated kraft gives a natural, bakery feel, while matte or gloss lamination helps on white board.
Foil stamping, spot UV and embossing work well on the lid for gift ranges. Plan your artwork around the fold lines using Design Your Box on our site before you send files.
Packing tips for six corner boxes
Set up a day's worth of boxes at the start of a shift and stack them open. The glued corners hold their shape, so stacks stay square.
For cakes, slide a board or a doily under the cake first so it can be lifted out cleanly. Close the lid gently and press the tuck flap home with two fingers rather than pushing the lid centre.
If you add tissue for clothing, fold it over the garment before closing so the edges do not catch in the tuck.
A sticker or a band of ribbon across the front stops curious hands lifting the lid on a display shelf. It also tells the customer nobody has opened the box since it was packed.
Common mistakes to avoid
Most problems we see with this style come from measuring or planning artwork too quickly. A few minutes of checking saves a reprint.
- Measuring the cake board rather than the decorated cake, then finding the lid presses on piping
- Choosing a tall wall for a flat product, which leaves items sliding about
- Placing text across the back hinge where it will crease every time the lid opens
- Picking folding board for a heavy hamper that really needs E flute
- Forgetting inside print until after the proof is approved
Can six corner boxes be posted?
They are built for hand-over and counter use, so the tuck front is not meant to survive a parcel network alone. For posting, place the box inside an outer carton or tape the lid closed.
If most of your orders go by post, a locking mailer box made to size is usually the better buy. Many shops order both: six corner boxes for the counter and mailers for online sales.
Shops that sell both in person and online often keep the same artwork on both box styles. Customers then recognise the brand whether the parcel arrives by post or is handed over the counter.
Ask for both on one quote if you need them. We can match the print colours across the two styles so they sit well together on a shelf.

Six Corner Boxes: questions
12 answersWhy is it called a six corner box?
The name comes from the six glue points added during manufacture. They are what let the box pop up from flat without any tape.
Do I need glue or tape to assemble them?
No. The corners are already glued, so you lift the walls and the box takes shape. Tape is only needed if you post it without an outer carton.
Are six corner boxes good for cakes?
Yes, they are a common bakery choice. Allow clearance above the tallest decoration, and choose E flute if the cake is heavy or tiered.
Can I add a window to the lid?
Yes. A cut-out window can be placed in the lid so customers can see the contents. Mention it when you ask for a quote.
Will the boxes stack when filled?
They stack well when the contents sit below the lid line. Keep heavier boxes at the bottom and avoid stacking very tall piles of iced goods.
Can you print inside the lid?
Yes. Inside print can go on the underside of the lid and on the tray floor, which gives a nice surprise when the box opens.
What is the smallest size you can make?
Small trays around 100 mm square are often requested for single cupcakes and favours. Send your size and we will confirm it on the quote.
Do they arrive flat?
Yes. They come flat with the corners already glued, which saves shelf space until you need them.
Should I line the tray for oily food?
For buttery pastries or anything moist, a sheet of greaseproof paper or a cake board keeps marks off the box floor. Dry or wrapped items can sit straight on the board.
How long until I receive my order?
Production is 4–6 business days after proof approval, then tracked delivery takes 2–3 business days.
Can I order one plain batch and one printed batch?
Yes. Many shops keep plain kraft for everyday use and a printed run for gifts or seasonal ranges. We can quote both together.
What if the boxes arrive damaged?
Send photos within 10 days of delivery. We will reprint or refund any misprinted, damaged or faulty boxes.
