Biodegradable Take Out Container Small Single Comp 6x6x3 - CASE

C · Moderate

Lower concern, plant-fiber food containers typically avoid PFAS, but no brand disclosure confirms it.

Verdict: BuyPlant-fiber molded pulp avoids known leaching hazards; no brand safety issues on record; suitable for cold and moderately warm food.

Biotrem's molded fiber containers are made from renewable plant fibers and are marketed as compostable and biodegradable. The material class, uncoated or minimally coated fiber, does not typically require PFAS-based water or grease barriers.

The full breakdown

What it's made of and why it matters

Biotrem containers are molded from plant fiber (typically bagasse from sugarcane processing or virgin wood pulp), compressed without plastic lining or synthetic coatings. This material class does not leach BPA, phthalates, or other endocrine-disrupting chemicals common to plastic food packaging. The fiber matrix is inherently resistant to degradation at room temperature and during storage of dry or cold foods, eliminating the chemical migration risk that drives concerns with petroleum-based alternatives.

The brand's record and disclosure

Biotrem maintains minimal public safety disclosure on their website; no third-party certifications (FDA, NSF, BPAC) are visible in mainstream sources. The brand does not explicitly address PFAS, heavy metals, or off-gassing, a common silence among smaller compostable-packaging producers. No recalls, contamination incidents, or regulatory warnings for Biotrem products appear in public records. Their positioning emphasizes compostability and sustainability rather than chemical safety, which is typical for the segment but limits transparency.

How it compares in its category

Molded-fiber containers rank below plastic clamshells (BPA/BPS risk) and above waxed-paper boxes (potential PFOA coatings in some brands). Unlike polystyrene foam or polypropylene, fiber pulp does not off-gas volatile organic compounds into food under normal storage. Biodegradability and compostability are strengths, but they do not address chemical safety; however, the base material profile is cleaner than single-use plastic competitors for short-term food contact.

If you buy it

Use for cold and room-temperature foods (salads, dry goods, bakery items); avoid prolonged contact with hot liquids above 65 degrees Celsius, as heat may accelerate minor fiber degradation and particle shedding. Do not microwave; direct flame contact risks charring. Replace containers if visible mold, softening, or moisture damage occurs, particularly in humid storage. Compost or discard after use; do not reuse for repeated food contact.

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.”

Possible

Microfiber shedding from fiber degradation

Molded pulp can shed small fibers if wet, compressed, or stored in high humidity. While food-contact-grade pulp is generally food-safe, visible debris or soft spots indicate deterioration and should trigger replacement. No recalls specifically for Biotrem on this issue are on record.

Possible

Mold and microbial growth if wet-stored

Plant-fiber containers absorb moisture and can support mold if stored in damp conditions before use or if pre-filled food releases condensation. Proper dry storage and prompt use mitigate this. No brand-specific contamination incidents are documented.

None known

Formaldehyde resins in binding agents

Food-grade molded pulp typically uses minimal synthetic binders; if present, formaldehyde levels in food-contact pulp are regulated to very low thresholds in most jurisdictions. No reports of excess formaldehyde off-gassing from Biotrem containers exist.

None known

Heavy metals in pulp feedstock (lead, cadmium)

Bagasse and virgin wood pulp carry no inherent heavy-metal risk if sourced from uncontaminated agricultural or forestry inputs. Biotrem does not disclose feedstock origin, but no contamination events are on public record. Standard food-contact material regulations would flag any batch with measurable heavy metals.

None known

Bleach residues (chlorine compounds)

Molded pulp may be chlorine-bleached during manufacturing to whiten and sterilize. Food-contact-grade pulp is rinsed extensively; regulatory limits on residual chlorine are strict. No testing data for Biotrem bleach residues is publicly available, but no incidents suggest noncompliance.

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.
