Plant-Fiber 29 oz Fiber Lunch Trays — Why the Material Matters
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 29 oz fiber lunch trays. The interior is lined with a thin PLA bioplastic film — itself plant-based, made from corn or sugarcane starch — to provide a grease and liquid barrier without resorting to PFAS chemistry. The result is a foodservice container that does not compromise on heat, structure, or end-of-life recovery.
The 10.0 × 7.0 × 1.5 in profile and 29 oz capacity fit single-portion entrées, sides, salads, parfaits, and school-lunch components. The case of 400 is sized for catering, school dining, hospital foodservice, hotel banquets, and operators transitioning out of foam.
Where this container earns its place on the line
- Saucy hot menu items — pasta in sauce, curries, gravy-rich plates, BBQ, stew — the PLA film stops soak-through.
- Catering with mixed wet and dry components — single tray for entrée plus side without compromise.
- Frozen meal-prep with sauces — freezer-safe lining survives cold storage and thaw.
- Ghost kitchens and delivery brands — 30-minute travel without bottom failure on saucy plates.
- Hospital and senior-living trayed meals — reheat-in-place for soft, saucy, or moisture-rich dishes.
- Dressed salads and grain bowls — the lining contains dressing migration during transport.
Five problems this SKU is engineered against
1. Soak-through on saucy or wet menu items
The PLA film on the inside surface stops liquid migration so the bottom stays dry through service, transport, and reheat — for sauced pasta, curries, BBQ, dressed salads, and stew.
2. 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.
3. Plastic-in-the-microwave concerns
Foodservice teams reheating prepared meals don’t want plastic film against hot food. This container is microwave-safe at reheat temperatures and plant-based PLA replaces conventional PE film for the grease barrier.
4. 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.
5. PFAS food-packaging laws tightening every year
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 ban intentionally added PFAS in food packaging. These do not contain added PFAS at any stage of manufacture.
Build, materials, and operator features
- No added PFAS — meets every U.S. state PFAS food-packaging law as of 2026.
- PLA bioplastic lining — plant-based film bonded to the food contact surface for grease and liquid barrier.
- Unbleached plant fiber body — denser than coated paperboard; holds shape under heavy or saucy meals.
- Hot food safe to 220°F — soups, stews, hot pastas, curries, casseroles, baked dishes.
- Microwave safe at reheat temperatures — reheat without transferring.
- Freezer safe — does not embrittle below 0°F; meal-prep ready.
- Liquid and grease resistant — PLA film barrier on top of naturally oil-resistant fiber.
- Composts in 2–4 months in a commercial composting facility, ≤12 months in home compost.
- Case of 400 — 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.

Frequently asked questions
How many compartments does this fiber lunch tray have, and what fits in each?
This fiber lunch tray has 3 compartments — designed for plated foodservice with separated entrée, sides, and a small accompaniment. Typical use cases include school lunch programs (entrée + 2 sides), hospital trayed meals, airline-style catering, and bento-style takeout. Each compartment is sealed-bottom so there is no cross-contamination of dressings or sauces between sections.
Does this fiber lunch tray hold up under saucy or steaming hot dishes?
Yes. The body is rated for hot food up to 220°F. The PLA lining is stable up to that temperature in food contact. Hot pastas, curries, soups (with a lid), stews, and baked entrées hold without warping.
What is the composting timeline for these fiber lunch trays?
In a commercial composting facility (ASTM D-6400 conditions), it breaks down in 2 to 4 months. In a properly maintained home compost system (TÜV AUSTRIA OK compost HOME), it takes 6 to 12 months depending on temperature, moisture, and turning frequency.
How big is the fiber lunch tray — will it fit in a standard takeout bag?
Outer dimensions are 10.0 × 7.0 × 1.5 in (25.4 × 17.8 × 3.8 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.
What is the case and pallet configuration for these fiber lunch trays?
Yes. They stack tightly when empty (400 per case, 40 cases per pallet for 16,000 units per pallet) and stack safely with a lid when filled. The footprint fits standard foodservice slots and delivery bags.
Do these fiber lunch trays qualify for school district biobased and PFAS-free procurement requirements?
Yes. They meet PFAS-free, biobased, and compostable procurement requirements many state school systems now mandate: no added PFAS, double TÜV compostability (HOME and INDUSTRIAL), USDA Biobased, ASTM D-6400, NSF Certified Compostable. Documentation is available on request.
Do you sell matching lids for these fiber lunch trays?
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.
Can I microwave food in the fiber lunch tray?
Yes, the fiber lunch tray is microwave safe at reheat temperatures. Reheat without transferring to another plate. Avoid using in conventional ovens above the rated heat tolerance or under broilers.
Do these meet California AB 1200 and New York PFAS food packaging regulations?
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.
