34oz Compostable Eco Friendly Container Trays
Skip until the brand discloses waterproofing chemistry used.
Compostable containers labeled eco-friendly often rely on fluorinated coatings for grease and moisture protection. This brand makes no statement about PFAS content or waterproofing method.

What 34oz Compostable Eco Container Trays is made of, ingredients and materials
These containers are marketed as compostable resin (likely polylactic acid/PLA or polyhydroxyalkanoate/PHA blend) with added waterproofing treatment. The waterproofing agent is not specified by the brand, which is the critical gap, compostable plastics alone are hydrophilic and break down in moisture, so a coating or chemical additive is necessary to make them water-resistant for food use. Without knowing what that coating is, you cannot assess leaching risk or whether it degrades into the food during heating or acidic/fatty food contact.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
Vague safety claims only
Uses vague language ("eco-friendly", "clean") without a specific PFAS statement.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
PFAS
Compostable resins require a waterproofing additive or coating. The brand does not specify what this is. PFAS and other fluorinated compounds are standard in the food packaging industry for this purpose; leaching risk into fatty or hot foods cannot be ruled out without composition data.
Source, ATSDR ↗Microplastics
If the waterproofing coating is a thin polymer layer or paraffin wax, repeated heating, cutting, or contact with acidic foods may cause flaking or shedding into food. No data exists on the durability of the brand's specific coating formulation.
Source, EPA ↗Composting claim unverified
The container is labeled compostable but may only break down in industrial high-heat facilities; home compost and most municipal programs will not accept it. If it ends up in landfill or environment, the waterproofing coating may persist and leach for years.
What’s reassuring
BPA & bisphenols
PLA and PHA resins are generally free of BPA by design, but some compostable blends include additives for flexibility. The brand has not disclosed whether additives are present or tested. Heating or prolonged contact with acidic liquids increases theoretical leaching risk for any plasticizer present.
Source, FDA ↗Heavy metals
Compostable resins sometimes contain colorants or reinforcing agents (calcium carbonate, talc) that may carry trace metals. No third-party testing or certification (e.g., NSF, FDA) is publicly available for this product to rule this out.

The brand's record and disclosure
The brand has not published material safety data sheets (MSDS), third-party test results, or detailed composition information for this product line publicly available. The brand shows no transparency on waterproofing chemistry or certifications beyond generic 'compostable' claims. No established recalls or controversies are on record, but silence on composition is a red flag in a category where PFAS and other water-repellent chemicals are common industry practices.
How it compares in its category
Compostable food containers occupy a murky middle ground, they avoid persistent plastics like polystyrene or polycarbonate, but many brands still use PFAS-based waterproofing (perfluorinated compounds) to meet grease and moisture barriers. Better-documented alternatives from larger brands (Footprint, World Centric) publish waterproofing ingredient lists; some use silicone or paraffin wax instead. The brand's silence puts it at a disadvantage compared to competitors willing to disclose what's in their coatings.
If you buy it
Do not use these containers for hot or oily foods until the brand confirms the waterproofing additive. Heat and fat accelerate leaching from unspecified coatings. Store dry food only at room temperature. Composting claims are only valid if your facility accepts the specific material (PLA or PHA), and many municipal programs do not. Request a full MSDS and waterproofing ingredient list from the brand before purchase; if they refuse, choose a competitor with published safety data.
