Custom Printed Clamshell Burger Boxes with Press Tab Lid

What is a clamshell burger box?

A clamshell is a box shaped in one piece, with the lid joined to the base along a hinge. It opens and closes like a shell.

The clamshells in our photos have a deep square base, rounded corners and ribs across the lid. A small tab on the lid presses into a slot on the base to hold it shut.

Unlike a folded burger box, a clamshell needs no assembly. You take one off the stack, open it and fill it.

The press tab is easy to open with one thumb, so customers do not tear the box to get in. It also closes again if they want to save half for later.

How does a clamshell differ from a folded burger box?

Both carry a burger well, but they handle storage, speed and branding in different ways. This table sets the two side by side.

Which kitchens prefer clamshells?

Clamshells suit kitchens that value speed at the pass over storage space. They also suit wet food that might leak from a folded box.

They also help when staff numbers are low. One person can serve and box without stopping to fold, which keeps queues moving at busy events.

• Burger vans with no time to fold boxes during a rush
• Breakfast counters serving rolls, muffins and hash browns
• Cafés selling a hot lunch with gravy or sauce
• Event caterers handing out hundreds of hot portions
• Takeaways with saucy burgers like pulled meat or chilli

What size clamshell suits a standard burger?

Clamshells are measured closed, across the base and up to the top of the lid. A standard burger usually fits a box of about 150 mm square.

Remember that rounded corners and sloped walls take some space. The usable floor is smaller than the outside size, so check the inside base against your bun.

Our guide to food packaging sizes in the UK compares clamshells with folded box sizes if you are switching styles.

Why does the lid have ribs?

The ribs stiffen the lid so it holds its shape when boxes are stacked in a bag. Without them, a wide flat lid would flex under weight.

They also lift the inside of the lid slightly off the food. That stops a tall bun sticking to the lid when the customer opens it.

The deep base works the same way for the floor. Sauce gathers at the bottom instead of running out of a corner.

Can clamshell burger boxes be printed?

Branding depends on the material, and we confirm print options on your quote. Some clamshell materials take simple print, while others are best left plain.

Many shops use a plain clamshell and brand the order around it. A printed wrap on the burger, or a printed bag for the box, carries the logo instead.

If full colour print on the box itself matters most, a folded board box may suit you better. We can quote both so you can compare.

Heat, steam and grease in a clamshell

A closed clamshell holds heat well because the lid seals all round. That same seal traps steam, so crisp toppings soften on long trips.

For crispy chicken, leave the tab open for a few seconds before closing so the first burst of steam escapes. Or wrap the burger in paper, which takes up some moisture.

Food-contact materials are available on request for clamshells, with the material confirmed on your written quote. Tell us what you serve so we match it.

Can clamshells work with burger paper and bags?

Yes, and this is how most shops brand a plain clamshell. A printed sheet under or around the burger shows your logo the moment the lid opens.

A printed paper bag for the closed box adds a second layer of branding for collection orders. It also gives the customer a handle to carry it by.

Pairing the two keeps your costs on the box down while the customer still sees your name twice. Our range of burger and fast food packaging shows the papers and bags that go with it.

Pick paper sizes that fold inside the clamshell base without bunching. Too much paper lifts the burger and stops the lid closing flat.

How do you store and use clamshells?

Clamshells come nested, so plan shelf space before a large order arrives. These steps keep them clean and quick to use.

Stacking full clamshells too high in a hot bag is another error. The bottom lids are strong, but heat softens them over a long trip.

1. Keep nested stacks in their outer cartons until you need them.
2. Store them off the floor and away from the fryer and grill.
3. Pull one box at a time from the top of the stack.
4. Fill the base, then press the tab firmly until it clicks.
5. Write order notes on a sticker, not on the lid itself.

What do buyers get wrong with clamshells?

Underestimating storage is the top mistake. A box of nested clamshells takes far more room than the same number of flat board boxes.

Some buyers also expect full colour print as standard. Check branding options on the quote before you plan artwork around the lid.

Lastly, a clamshell sized by outside measurements alone can be too tight inside. Always compare the inside floor with your bun.
