Matter Compostable Food Storage Container 5ct

A · Very low PFAS

Lower-concern choice; compostable fiber packaging avoids traditional PFAS coatings found in conventional containers.

Verdict: BuyPlant-based fiber packaging without traditional PFAS coatings; strong brand transparency on materials and compostability claims.

Footprint's compostable food containers are made from plant-based fiber without synthetic Teflon-family coating coatings, aligning with their PFAS-free positioning. Compostable certification provides third-party verification of material composition.

Brand says: “Footprint explicitly markets containers as PFAS-free and compostable, positioning against traditional food packaging coatings.

Why this grade

Category baseline

food packaging is a category where PFAS exposure is more common.

Hurts the grade

Brand-stated PFAS-free

The brand states the product is PFAS-free (self-declared).

Helps the grade

Safe base material

Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).

Helps the grade

The full breakdown

What it's made of and why it matters

Matter containers are molded from plant-based fiber pulp (typically sugarcane bagasse or similar agricultural residue), avoiding the plastic polymers and fluorinated coatings common in conventional food storage. This material composition eliminates the chemical architecture that normally requires PFAS water and grease barriers in competing products. Plant-fiber packaging is designed to break down in industrial composting environments within 90-180 days, reducing the persistent chemical exposure pathway of durable plastics.

The brand's record and disclosure

Footprint is a certified B Corp with public material sourcing standards and third-party compostability certifications (BPI, ASTM D6868). The company has published detailed product ingredient disclosures and maintains transparent supply chain documentation. No material controversies, recalls, or substantiated chemical safety violations have been reported for this product line as of public record.

How it compares in its category

Plant-fiber containers like this avoid the PFAS-heavy Teflon-family coating coatings found in most bleached paperboard and conventional plastic food storage. Compared to uncoated fiber containers, they retain structural integrity without relying on per- or polyfluorinated chemistry. They occupy a middle-ground cost and practical performance tier between fully compostable single-use alternatives and durable reusable plastics.

If you buy it

These containers are designed for cold to ambient-temperature foods; avoid prolonged microwave use or contact with hot liquids (above 50°C/122°F), as fiber softening accelerates at elevated temperatures and can compromise structural integrity. Store in cool, dry conditions to prevent mold growth in fiber interstices before use. After disposal, confirm access to industrial composting facilities in your area, as home composting may not reach temperatures necessary for reliable degradation. Do not reuse containers beyond their designed lifespan (typically 6-12 months of standard use).

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

Bacterial/fungal growth in cellulose matrix

Plant-based fiber is hygroscopic and can harbor microbial growth if stored in humid conditions before use or if containers are not dried after washing. This is a storage/maintenance issue rather than an inherent chemical hazard.

None known

Coating leachables (proprietary barriers)

Footprint does not disclose use of traditional synthetic binders or barrier coatings for these containers; no public reports of leaching from the plant-fiber matrix itself exist. Any water or grease resistance appears to rely on fiber density and surface treatment rather than fluorinated chemistry.

None known

Formaldehyde in processing resins

No evidence of urea-formaldehyde or phenol-formaldehyde binders in Footprint plant-fiber containers. Industrial pulp molding typically does not require these resins for structural integrity in this application.

Possible

Microplastic generation or fiber shedding

Fiber containers may shed small cellulose fragments during handling or extended food contact, particularly if abraded or degraded. Risk is low but present; fragments are biodegradable and not persistent microplastics in the synthetic sense.

None known

Ink/printing chemical transfer

Footprint uses food-contact-safe inks on branded containers; no substantiated reports of dye or pigment migration into stored food. Standard due diligence applies: avoid contact of printed surfaces with food when possible.

What we don’t know

This grade is a model-based estimate from public materials, coatings, and brand disclosure at 82% 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.

Formulations and coatings change between production runs. Always check the current label before buying.
