3-Comp 200 Pack Compostable Disposable Food Containers with Lids
Avoid until the brand reveals its coating chemistry publicly.
Compostable containers often use fluorine-free grease barriers, but this brand provides zero coating transparency. Compostability certification doesn't guarantee PFAS absence, as many compostable products contain PFAS alternatives in their grease layers.

Material
Compostable resin blend (likely PLA/PBAT) with grease-resistant coating
Brand disclosure
Brand is silent on PFAS
Lab data
No public lab test
What’s concerning
Waterproof / stain-resistant treatment
Water-repellent treatments have historically contained PFAS chemicals.
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
Category baseline
food packaging is a category where PFAS exposure is more common.
PFAS
Grease-resistant coatings on compostable food containers typically contain fluorinated chemicals; Compose's refusal to disclose coating chemistry is consistent with use of legacy or emerging PFAS alternatives. This is the primary non-PFAS hazard of concern for this product class.
Source: ATSDR ↗PLA polymer migration at elevated temperatures
PLA has a lower glass transition temperature than conventional plastics (around 140°F); exposure to hot foods or liquids can increase leaching of oligomers and residual monomers. No recalls or widespread reports exist, but use below recommended temperature limits is prudent.
What’s reassuring
Microplastics
No established reports of microplastic shedding from compostable food containers in normal use. Risk is primarily in landfill or marine persistence if not industrially composted, not in the food itself during intended use.
Source: EPA ↗Formaldehyde / VOCs
PLA/PBAT blends do not require formaldehyde-based resins or flame retardants. Off-gassing is not a documented concern for this material class, unlike conventional polystyrene or certain recycled plastics.
Source: ATSDR ↗Heavy metals
No known reports of heavy metal contamination in mainstream compostable food container products. Compose does not disclose pigment or additive sources, but no recalls or testing alerts exist for this brand.

What it's made of and why it matters
These containers are made from a blend of PLA (polylactic acid, corn-based) and PBAT (polybutylene adipate terephthalate, biodegradable polyester), designed to break down in industrial composting. The grease-resistant coating is the critical unknown: most food service compostable containers use fluorinated coatings (PFAS chemicals) to repel oils and prevent leaching, even though compostable materials themselves are less prone to leaching than conventional plastics. Compose has not publicly disclosed its coating chemistry, which is a red flag for transparency in this product class.
The brand's record and disclosure
Compose's public stance on PFAS and coating chemistry is silent across available sources. The brand does not list certifications like OK Compost or explicit non-PFAS commitments on its product pages. This lack of transparency is particularly concerning because grease-resistant coatings are the primary source of PFAS in food packaging, and compostable material manufacturers vary widely in their coating choices. Without third-party testing or manufacturer disclosure, you cannot verify whether this product contains legacy PFAS (like PFOA) or newer alternatives that may carry similar persistence concerns.
How it compares in its category
Compostable food containers are generally safer than conventional plastic in terms of BPA and phthalate exposure, since PLA/PBAT formulations do not require these chemicals. However, they still rely on grease-resistant coatings, and many competing brands (such as World Centric or Footprint) explicitly state non-PFAS coatings or carry OK Compost certification as a transparency marker. Compose's silence on this point places it below the transparency baseline of responsible competitors in the compostable segment.
If you buy it
Use these containers only for room-temperature or lukewarm foods; do not microwave or expose to hot liquids above 140°F, as heat can increase migration of coating chemicals into food or degradation of the base polymer. Compost them in an industrial facility (not backyard compost), since home conditions will not break down PLA/PBAT adequately. Replace any containers showing visible cracks, discoloration, or grease saturation, as these are signs the coating is failing. If the product ends up in landfill or marine environments, it will persist for decades despite the compostable label.
