Clamshells are hinged-lid bagasse boxes — the canonical compostable burger box, sandwich box, dosa wrap, and event-catering takeaway format. Sizes from a 5 × 5-inch single-burger box to a 10 × 6-inch 2-compartment combo. The 7 × 5-inch burger clamshell is the cloud-kitchen high-volume SKU; the 8 × 8 and 9 × 9 with 3-compartment variants cover combo meals (main + side + dip in one box).
Clamshells solve two problems containers don't: the hinge holds the lid attached so it doesn't get lost in delivery, and the deeper box profile fits taller items (burgers, sandwiches, dosa folds) without crushing. They're slightly more material per unit than equivalent-volume containers, but the convenience pays off for cloud kitchens where the customer is opening the box at home with one hand on the phone.
Made by manufacturing partners certified for FDA food-contact compliance, BPI, EN 13432 and ISO 22000; PFAS-free per manufacturer test reports. Microwave-safe at 700–1000 W for 3 minutes (lid open). HSN 4823 at 18% GST.
Bagasse clamshell vs disposable plastic vs PE-coated paper
| Dimension | Disposable plastic | PE-coated paper | Bagasse (PulpyWare) |
|---|---|---|---|
| Source | Petroleum-derived virgin polymer | Virgin paper + polyethylene plastic liner | Sugarcane juice residue — agri-waste, no virgin pulp |
| Compostability | Never composts — 450+ years to break down | Paper rots, PE liner persists as microplastic | ~90 days in commercial composting; longer at home |
| PFAS / forever-chemicals | None added (uses plastic itself) | Many brands use PFAS for oil/grease repellency | PFAS-free per our manufacturers' test reports |
| Microwave safety | Most plastic deforms above 80 °C | PE liner can leach plasticisers when heated | Tested at 700–1000 W for 3 minutes — fibre stays inert |
| Oil & sauce hold | Excellent (it IS plastic) | Excellent — but at the cost of the lining | Excellent for 1 hour — natural fibre absorbs no oil |
| End-of-life | Landfill or ocean — non-degradable | Not recyclable (lined paper isn't accepted in most MRFs) | Backyard compost, municipal organics, or biogas |

Who's buying clamshell containers from PulpyWare?
Burger chains & QSR
7×5-inch burger clamshell is the cloud-kitchen high-volume SKU — sized for a stacked burger with a small fries side. The hinge keeps the lid attached so it doesn't get lost in delivery. Bengaluru and Mumbai chains use 6,000 units/month per outlet.
Café takeaway
8×8 single-compartment for dosa, wraps, sandwiches; 9×9 3-compartment for breakfast combos (main + side + dip). Cafés like that the matte fibre surface photographs well — no shiny plastic glare in the Instagram shot.
Event catering
Hand-out boxes at corporate events, food courts, festival catering. The 8×8 single is the canonical event format — a sandwich + chip bag fits, the lid clicks shut, and the customer walks away. Free shipping above the HORECA threshold.

Frequently asked questions
Are bagasse clamshells leakproof for burger juices and sauces?
The hinge keeps the lid attached but the seam isn't fully liquid-tight — small amounts of burger juice or oil are fine for the duration of delivery. For very saucy items (a wet biryani), switch to a leakproof container-with-lid instead. The clamshell shines for solid items with light sauce.
What's the difference between a 1-compartment and 3-compartment 8 × 8 clamshell?
Same outer footprint (8 × 8 inch, 200 pcs/carton) but the 3-compartment has two raised dividers inside, splitting it into one large bay (main) and two smaller bays (side + sauce). Pick 3-compartment when you want presentation separation; pick single when you have one large item like a sandwich.
Can I microwave a clamshell with food in it?
Yes — open the lid first, then microwave at 700–1000 W for 3 minutes. The fibre is rated for the temperature. Closed-lid microwaving traps steam and weakens the hinge over time.
Which clamshell size for a typical Indian burger menu?
7 × 5-inch single compartment is the standard burger box — sized for a stacked burger with a small side of fries. The 8 × 8 single is the next step up for double-stack burgers. The 8 × 8 3-compartment is for the burger + fries + dip combo.
How are clamshells priced for high-volume cloud-kitchen reorders?
Verified HORECA buyers see ~20% off D2C list. The 7 × 5 burger clamshell at 6,000 boxes/month is where the gap is most meaningful. NET-15 invoice terms, dedicated POC. Apply at /wholesale/.
