Bagasse Compostable Lunch Box 9x6 Inch White
Better choice than plastic, though the brand won't confirm coating details.
Made from sugar cane fiber waste, this lunch box needs no water-resistant coating since it's compostable. The material itself poses minimal PFAS risk.

What Bagasse Compostable Lunch Box 9x6 White is made of, ingredients and materials
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.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
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.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
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 & bisphenols
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.

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 present lower concern 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, lower concern 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.
