Bagasse Compostable Lunch Box 9x6 Inch White
Lower-concern choice: bagasse is a plant fiber with no inherent PFAS risk, but brand silence on coatings leaves small uncertainty.
Bagasse lunch boxes are made from agricultural waste (sugar cane fiber) and do not typically require fluorinated water-resistant treatments because they are designed for composting, not reuse. Biopac UK provides no public disclosure of PFAS testing or claims, which is standard for this material category.

Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
Bagasse is the fibrous residue left after sugar cane juice extraction, pressed and molded into pulp-based food containers. Unlike plastic or ceramic, bagasse has no synthetic polymer matrix, plasticizers, or glazes that typically leach chemicals into food. The material is inherently biodegradable and compostable, with no known migration of toxic compounds under normal food contact conditions. This product appears to use unbleached or minimally processed bagasse, which reduces chemical processing inputs.
The brand's record and disclosure
Biopac UK has not published detailed material safety data sheets or third-party certifications visible in public records for this specific product line. The brand markets the range as compostable and eco-focused but does not explicitly disclose coating additives, bleaching agents, or adhesives used in manufacture. No recalls or safety complaints for Biopac bagasse containers are on record. The lack of transparency on processing chemicals is a minor gap, though bagasse itself carries minimal inherent toxicity risk.
How it compares in its category
Bagasse containers are safer than polystyrene foam (which can leach styrene) and polypropylene (which may degrade and shed microplastics under heat). They avoid the PFAS-coating concern present in some compostable plastics marketed as grease-resistant. Compared to wax-coated paper or molded-fiber products, bagasse requires fewer chemical additives for water resistance. Among plant-fiber lunch boxes, bagasse is a middle-ground choice: safer than plastic alternatives but with less disclosure than some certified compostable brands.
If you buy it
Do not microwave or expose to high heat above 120°C (248°F), as pulp degradation and potential fiber shedding can occur. Hand wash rather than dishwasher to preserve structural integrity; the material softens with repeated high-temperature water exposure. Replace after visible wear, splitting, or mold growth (typically after 50-100 uses). Store in a dry environment to prevent premature decomposition; moisture can trigger mold before intended composting.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Bleaching agents or processing chemical residues
Bagasse pulp is often bleached or treated with adhesives during manufacture. Biopac does not disclose specific agents used; chlorine-based bleaches or formaldehyde-containing binders are possible but not confirmed for this product.
Microplastic or fiber shedding
Unlike synthetic plastics, bagasse can gradually degrade and shed cellulose fibers, especially if overheated or abraded. Risk is low under normal use but increases with repeated hot-water washing or microwaving.
Mold or bacterial growth if stored wet
Plant-fiber containers retain moisture and can support mold colonization if not dried and stored properly. This is a usage issue rather than a manufacturing hazard but common in compostable pulp products.
Adhesive or coating toxins (unspecified)
Bagasse containers typically use food-safe starch or plant-based glues, but Biopac's product label does not specify the adhesive type. No evidence of toxic adhesives in this product class, but brand transparency is limited.
BPA or BPS in coatings
Bagasse is not typically coated with epoxy or polycarbonate-based resins that contain BPA/BPS. Risk is negligible unless a synthetic polymer layer has been added, which is not indicated in available product information.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 78% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
