Key takeaways

-   A bagasse clamshell is a one-piece hinged food box molded from sugarcane fiber, with the lid and base formed together and a locking tab; a bagasse burger box is a compact clamshell sized for burgers and sandwiches.
-   The most common sizes are about 6 × 6 in (15 × 15 cm) for burgers, 9 × 6 in (23 × 15 cm) for meals and wraps, and 8 × 8 or 9 × 9 in square boxes, often with two or three compartments.
-   Bagasse clamshells are the most direct replacement for expanded polystyrene (EPS) foam boxes, which are banned as food containers on the EU market under the Single-Use Plastics Directive.
-   Ekoroll bagasse clamshells are home compostable and 100% bagasse (TÜV AUSTRIA OK compost HOME), PFAS-free, water- and oil-resistant, and suitable for hot and cold food.
-   Test clamshells in a delivery bag with your hottest, greasiest dish: check that the tab stays locked, the lid does not collapse with steam and fries stay crisp.

A bagasse clamshell is a one-piece hinged food box molded from sugarcane fiber, with the lid and base formed together and a locking tab; a bagasse burger box is a compact clamshell sized for burgers and sandwiches. To choose one, start from the menu: pick the footprint for the portion — about 6 × 6 in for a burger, 9 × 6 in for meals and wraps, 8 × 8 or 9 × 9 in for full combo meals — add compartments if sides and sauces must stay apart, and test the closed box in a delivery bag.

This guide covers clamshell formats and sizes, which box suits which dish, hot and greasy food in delivery, bagasse compared with paper and foam boxes, the EU rules that apply and what to ask a supplier.

## What Is a Bagasse Clamshell?

Bagasse is the fiber left after sugarcane stalks are crushed for their juice. The fiber is pulped, formed in heated molds under pressure and trimmed. A clamshell is molded in one piece: base, hinge and lid together, with a locking tab that holds the lid shut. Ekoroll bagasse clamshells are **100% bagasse**, **home compostable** (TÜV AUSTRIA OK compost HOME; the certificate is held by the producing mill and a copy is available on request), **PFAS-free**, **water- and oil-resistant**, **microwave- and freezer-safe** and suitable for **hot and cold food**.

## Clamshell Formats and Sizes

| Format | Typical size | Best for |
| --- | --- | --- |
| Burger box | about 6 × 6 in (15 × 15 cm) | Single burgers, sandwiches, pastries |
| Rectangular clamshell | about 9 × 6 in (23 × 15 cm), roughly 800–1,200 ml | Meals, wraps, kebabs, mixed takeaway |
| Square clamshell, 1 compartment | about 8 × 8 in or 9 × 9 in | Large burgers with fries, full meals |
| Square clamshell, 2 or 3 compartments | about 8 × 8 in or 9 × 9 in | Mains with sides and salad, combo menus |
| Rectangular clamshell, 2 compartments | about 9 × 6 in | Main and side, rice and curry |

Sizes vary by range; ask for the current size list and test with your own portions.

## Which Clamshell for Which Dish?

-   **Burgers:** a 6 × 6 in burger box for a single burger; a square 8 × 8 or 9 × 9 in box when fries go in the same box.
-   **Burger and fries combos:** a square box with two compartments keeps fries away from the burger’s juices and sauces.
-   **Kebabs, wraps and grills:** a rectangular 9 × 6 in clamshell gives length for wraps and skewers.
-   **Mains with rice and salad:** a three-compartment square box keeps hot and cold parts apart.
-   **Very saucy dishes and curries in delivery:** a compartment clamshell or a dedicated [leak-resistant container](https://ekoroll.com/en/products/eco-packaging/leak-proof-bagasse-containers).

## Hot, Greasy Food and Delivery

Hot burgers and fried food release steam and grease. Three things keep them right in a bagasse clamshell:

1.  **Let very hot food breathe for a moment** before closing, so steam does not soften the bun or fries.
2.  **Separate wet and crisp items** with a compartment layout.
3.  **Do not overfill** — the locking tab must close without pressure on the food.

Test before ordering: pack your hottest and greasiest dish, close the box, put it in a delivery bag with drinks and other boxes, carry it for a typical trip, then check the tab, the base and the crispness of fries.

## Bagasse vs Paper vs Foam Burger Boxes

|  | Bagasse clamshell | Paper / kraft burger box | EPS foam box |
| --- | --- | --- | --- |
| Construction | One-piece molded fiber with hinge and tab | Folded paperboard, flat-packed | Molded expanded polystyrene |
| Rigidity | Rigid; holds shape in delivery bags | Lighter; depends on board | Light and rigid |
| Steam and grease | Water- and oil-resistant fiber (Ekoroll bagasse) | Depends on the barrier coating | Resists grease |
| Branding | Plain, embossed or custom-shaped with dedicated molds | Full-color logo print is easy | Limited |
| Storage | Nested stacks | Flat-packed, compact | Nested stacks |
| EU market | No plastic layer | Plastic-lined boxes count as single-use plastic food containers | EPS food containers are banned |
| Best for | Hot burgers and meals in delivery | Counter service, branding | — (not allowed in the EU) |

Many brands use both bagasse and paper: paper or kraft [burger, taco and fries boxes](https://ekoroll.com/en/products/eco-packaging/burger-taco-fries-boxes) for branded counter service, bagasse clamshells for delivery. See also our guide to [paper takeaway boxes wholesale](https://ekoroll.com/en/blog/paper-takeaway-boxes-wholesale).

## EU Rules for Burger Boxes and Clamshells

1.  **Single-Use Plastics Directive (EU) 2019/904.** Article 5 bans food containers made of expanded polystyrene, including boxes with or without a cover used for food eaten immediately from the container. Food containers made wholly or partly of other plastics, including plastic-lined paper and bio-based plastics such as PLA according to the Commission’s guidelines, fall under consumption-reduction measures and extended producer responsibility.
2.  **Packaging and Packaging Waste Regulation (EU) 2025/40.** Since 12 August 2026, food-contact packaging containing PFAS above set limits may not be placed on the EU market. Ekoroll bagasse is PFAS-free.
3.  **Food contact.** Ask every supplier for a declaration of compliance under Regulation (EC) No 1935/2004.

## What to Ask a Supplier

-   **Exact dimensions** of base and lid, and capacity in ml.
-   **Compartment layouts** available for each footprint.
-   **Closure:** how the locking tab holds in delivery; ask for samples to test.
-   **Documentation:** home or industrial compostability certificate and its holder, PFAS status, food-contact declaration.
-   **Packing:** units per sleeve and carton, carton size and weight.
-   **Custom development:** whether new footprints or layouts can be made with dedicated molds, and the minimum order for them.
-   **Lead time and minimum order:** confirmed in the quote.

## Frequently asked questions

### ### What is a bagasse clamshell?

A bagasse clamshell is a one-piece hinged food box molded from sugarcane fiber. The lid and base are formed together and close with a locking tab, so the box is filled, closed and handed over in one movement. Clamshells are used for burgers, meals, wraps, fries and mixed takeaway, in single- and multi-compartment versions.

### ### What size is a bagasse burger box?

The standard burger box is about 6 × 6 inches (15 × 15 cm), sized for a single burger or sandwich. Larger burgers, burgers with fries and meals use 8 × 8 or 9 × 9 inch square boxes or a 9 × 6 inch rectangular box. Exact dimensions vary by range, so check with a sample and your own burger.

### ### Can bagasse clamshells hold hot and greasy food?

Yes. Bagasse clamshells are used for hot food such as burgers, grills, fries and fried chicken, and Ekoroll bagasse is water- and oil-resistant and PFAS-free. For very wet or saucy dishes in delivery, choose a compartment layout or a leak-resistant container and test it with your own food.

### ### Do bagasse clamshells replace foam boxes?

Yes. Bagasse clamshells are the most direct alternative to expanded polystyrene (EPS) foam takeaway boxes. Under Article 5 of the EU Single-Use Plastics Directive, food containers made of EPS are banned from the EU market, so fiber clamshells are what most operators switch to.

### ### Bagasse burger box or paper burger box?

Both work. Bagasse burger boxes are molded in one piece with a hinge, are rigid and resist steam and grease without a coating, which suits hot burgers in delivery. Folded paper or kraft burger boxes are lighter, flat-packed and easy to print with a logo, which suits counter service and branding. Many brands choose by channel: paper for the counter, bagasse for delivery.

### ### Are bagasse clamshells microwave safe?

Ekoroll bagasse is microwave- and freezer-safe and suitable for hot and cold food. Reheat for a short time and do not use clamshells in a conventional oven or under a grill.
