Plant-Fiber Fiber Bento Boxes — 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 fiber bento boxes. 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.
Standard capacity in a 14.0 × 10.0 × 16.0 in footprint — designed to hold an entrée portion, a sandwich plus garnish, a saucy side, or a parfait. Cases of 300 stack tightly in the back of house and travel cleanly in delivery bags.
Where this container earns its place on the line
- Catering and event foodservice — single-portion service for boxed lunches, banquet plating, or buffet line setup.
- Meal-prep and ready-meal brands — freezer safe; meal-prep ready.
- Bakeries and delis — pastries, sandwiches, grab-and-go assemblies.
- Quick-service restaurants and cafes — single-portion entrées, sides, salads, fruit cups, parfaits.
- Hospital and senior-living foodservice — microwave-safe so kitchen staff can plate, deliver, and reheat in the same container.
- Hotels and corporate dining — clean visual presentation for breakfast assemblies, mid-meeting service, lunch buffets.
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. 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.
3. 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.
4. 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 has no film at all in the food path.
5. 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.
Build, materials, and operator features

Frequently asked questions
Will the fiber bento box survive reheating in the microwave on the line?
Yes, the fiber bento box 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.
What are the exact dimensions of this fiber bento box?
Outer dimensions are 14.0 × 10.0 × 16.0 in (35.6 × 25.4 × 40.6 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.
How do I confirm the PFAS-free claim on these fiber bento boxes?
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.
Which menu types work with this 5-compartment configuration?
This fiber bento box has 5 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.
How many fiber bento boxes fit on a pallet?
Yes. They stack tightly when empty (300 per case, 28 cases per pallet for 8,400 units per pallet) and stack safely with a lid when filled. The footprint fits standard foodservice slots and delivery bags.
Which lids fit this fiber bento box?
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.
What is the maximum hot-food temperature for this fiber bento box?
Yes. The body is rated for hot food up to 220°F. Hot pastas, curries, soups (with a lid), stews, and baked entrées hold without warping.
Which state PFAS food-packaging laws do these fiber bento boxes satisfy?
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.
How long does the fiber bento box take to compost?
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.
