Avant Grub Biodegradable 6x6 Take Out Food Containers with Clamshell Hinged Lid Mi
Lower concern, but brand transparency on PFAS absence would help.
Biodegradable food containers made from plant fiber typically avoid PFAS intentionally. No published lab data or brand claims confirm PFAS-free status.

Why this grade
Safe base material

Category baseline
food packaging is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
The full breakdown
What it's made of and why it matters
Avant Grub containers are molded from bagasse (sugarcane fiber residue) or similar plant-based pulp, a post-consumer agricultural byproduct. Unlike polystyrene or plastic-lined containers, bagasse does not rely on synthetic polymer coatings that can leach BPA, BPS, or phthalates into food. The material is naturally absorbent and designed for compostability, meaning it degrades in industrial composting facilities within 90-180 days, reducing accumulation of persistent chemicals in landfills.
The brand's record and disclosure
Compostables (the brand) does not publicly disclose testing results or third-party certifications for chemical content in their product line. The company claims compliance with FDA food-contact regulations but offers no detailed safety documentation, ingredient sourcing transparency, or PFAS absence statements on their website or packaging. This silence does not indicate the presence of hazards, but reflects a gap in proactive transparency common in emerging compostable packaging brands.
How it compares in its category
Bagasse-based containers sit at the lower end of chemical risk compared to polystyrene clamshells (which can off-gas styrene) or PLA plastic containers (which may contain processing additives). Competing plant-fiber brands like Footprint and World Centric provide similar safety profiles. However, few compostable packaging makers publish PFAS testing; this product is representative of that gap, not an outlier.
If you buy it
Store containers in a cool, dry place; moisture can promote mold or bacterial growth on uncoated fiber surfaces. Do not microwave, as high heat may degrade the structural integrity of bagasse and release fibers into food. Use for cold or warm (not boiling) foods; bagasse softens above 80-90 degrees Celsius. Replace after 1-2 years if stored long-term, as untreated fiber can become brittle and shedding.
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.”
Microorganisms and mold on fiber substrate
Untreated plant fiber is hygroscopic and can harbor bacterial or mold growth if exposed to moisture or humidity during storage. This is a handling and storage issue, not an inherent chemical hazard.
Fiber shedding into food at elevated temperatures
Bagasse containers are not thermally stable above 80-90 degrees Celsius. Microwave use or contact with boiling liquids may cause breakdown and fiber particles to migrate into food, though this is a physical rather than chemical risk.
Adhesives or processing residues in hinges
Clamshell hinges typically use food-safe glues, but no public testing data exists for Avant Grub specifically. Industry standard assumes compliance with FDA 21 CFR 175-178, but brand does not disclose adhesive suppliers or composition.
Residual pesticides or agrochemicals from bagasse feedstock
Bagasse is sourced from sugarcane processing waste; pesticide residue risk depends on agricultural practices and washing steps. Compostables does not disclose feedstock origin or testing for agrochemical residues.
BPA, phthalates, or other plastic additives
Bagasse-based products do not require these additives by design. No evidence of plastic contamination in this product line; risk is substantially lower than plastic-lined or PLA alternatives.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% 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.
