8×8″ Compostable Fiber Clamshell Containers for Foodservice & Catering

Sugarcane bagasse is the agricultural by-product left over after juice extraction — burning it pollutes, landfilling it wastes biomass, but molding it into food packaging captures that material as a renewable input. That is the body of these fiber clamshell containers. There is no plastic film, no wax coating, and no PFAS — the unbleached fiber itself is dense enough to resist oil and grease, and to compost cleanly as a single material. The result is a foodservice container that does not compromise on heat, structure, or end-of-life recovery.

Outer dimensions are 8.0 × 8.0 × 3.1 in — sized to fit standard foodservice slots, delivery bags, and catering carts. Each case ships 200 units, 45 cases per pallet for 9,000 units per pallet.

Where this container earns its place on the line

• Sustainability-minded brands publishing impact reports — third-party-certified compostable, biobased, and PFAS-free for transparent claims.
• Operations on commercial composting programs — industrial compostable; integrates into the existing organics bin.
• Procurement teams scoring USDA Biobased preference — USDA Certified Biobased Product, eligible under federal BioPreferred procurement.
• Operators displacing foam under city/state foam bans — drop-in replacement that survives hot food, unlike PE-coated paperboard.
• Buyers under state PFAS bans — no added PFAS — meets California AB 1200, New York Hazardous Packaging Act, Washington, Colorado, Maryland, Minnesota laws.
• Buyers with multi-state operations — single SKU compliant across the patchwork of state food-packaging laws.

Five problems this SKU is engineered against

1. Foam container bans without a true replacement

Polystyrene foam was the workhorse of school cafeterias and quick-service venues for decades. Foam is now banned or restricted in 11 U.S. states and over 250 municipalities. Most “alternatives” are PE-coated paperboard (still plastic, still not compostable) or thicker plastic (still landfill). A plant-based compostable container is the only fully sustainable substitute that survives hot food.

2. Grease resistance without synthetic coatings

Unbleached plant fiber is naturally oil and grease resistant — the barrier is the fiber itself, not a synthetic coating that fails after 30 minutes on the line.

3. Procurement asking for documentation

Buyers with sustainability mandates need certificates: USDA Biobased, ASTM D-6400, FDA food contact, NSF Certified Compostable, TÜV AUSTRIA. All applicable certifications are listed below; lab/cert documents are available on request for B2B accounts.

4. Multi-state compliance complexity

Operators running locations across 6+ states cannot stock a different SKU per jurisdiction. This product clears the strictest of the state PFAS and biobased food-packaging rules currently in force, so a single SKU works in California, New York, Washington, and any state that follows.

5. Compost contamination at the back of house

Single-material recovery — fully compostable with no plastic film, no wax, and no PFAS to separate from the fiber.

Build, materials, and operator features

• No added PFAS — meets every U.S. state PFAS food-packaging law as of 2026.
• Unbleached plant fiber body — denser than coated paperboard; holds shape under heavy or saucy meals.
• Hot food safe to 200°F — soups, stews, hot pastas, curries, casseroles, baked dishes.
• Oil and grease resistant — barrier is the natural fiber itself, no synthetic coating.
• Composts in 2–4 months in a commercial composting facility (industrial compostable).
• Case of 200 — sized for catering, school dining, and operator-scale foodservice.
• Gluten-free and allergen-friendly material.
• Unbleached natural fiber color — pairs with any branded sticker, ribbon, or sleeve.

Compliance, compostability, and food-contact certificates

• OK compost INDUSTRIAL (TÜV AUSTRIA) — disintegrates and biodegrades in a commercial composting facility within 12 weeks.
• ASTM D-6400 (ASTM International) — meets the U.S. industry standard for industrial compostability.
• FDA Food Contact Compliant (U.S. Food and Drug Administration) — conforms to U.S. Code of Federal Regulations for direct food contact.
• BPI Certified Compostable (Biodegradable Products Institute) — third-party industrial compostability certification.

Frequently asked questions

Do these fiber clamshell containers contain any added PFAS?

Yes. No PFAS chemicals are added at any stage of manufacturing. Grease and oil resistance comes from the unbleached plant fiber itself, not from PFAS coatings. They meet PFAS-restriction laws in California, New York, Washington, Colorado, Maryland, Minnesota, Connecticut, Rhode Island, Vermont, Hawaii, and other states banning intentionally-added PFAS in food packaging.

Can I serve hot food directly in the fiber clamshell container?

Yes. The body is rated for hot food up to 200°F. Hot pastas, curries, soups (with a lid), stews, and baked entrées hold without warping.

Are these fiber clamshell containers compliant with state PFAS bans nationwide?

Yes. Because no PFAS is intentionally added, they comply with California AB 1200 / AB 1201, New York’s Hazardous Packaging Act, and parallel laws in Washington, Colorado, Maryland, Minnesota, Connecticut, Rhode Island, Vermont, and Hawaii. Lab test reports are available for B2B accounts on request.

What footprint does this fiber clamshell container take on the prep line?

Outer dimensions are 8.0 × 8.0 × 3.1 in (20.3 × 20.3 × 7.9 cm). This footprint fits standard takeout bags, hot bags, delivery cubes, and most foodservice tray slots. Stack height in storage scales linearly with case quantity and shape.

Are these fiber clamshell containers stackable for storage and transport?

Yes. They stack tightly when empty (200 per case, 45 cases per pallet for 9,000 units per pallet) and stack safely with a lid when filled. The footprint fits standard foodservice slots and delivery bags.

Are these suitable for K-12 school lunch programs?

Yes. They meet PFAS-free, biobased, and compostable procurement requirements many state school systems now mandate: no added PFAS, TÜV AUSTRIA OK compost INDUSTRIAL, USDA Biobased, ASTM D-6400, NSF Certified Compostable. Documentation is available on request.

How fast do these fiber clamshell containers break down in commercial composting?

In a commercial composting facility (ASTM D-6400 conditions), it breaks down in 2 to 4 months. This product is industrial compostable only — it will not meaningfully break down in a backyard compost pile.

What lid options work with this fiber clamshell container?

Three lid options typically fit foodservice containers in this size range: clear PLA dome lids for visible merchandising of salads, parfaits, and bakery; clear PLA flat lids for stackable delivery; and matching plant-fiber lids for opaque, plant-based compostable closure. Lids are sold separately by the case — pair by capacity and footprint.
