EcoQuality Hinged Clamshell Takeout Containers
Grease-resistant coating source remains unclear, higher risk present.
EcoQuality clamshells feature an undisclosed grease-resistant coating common to takeout containers. The brand offers no PFAS disclosure or testing; conventional takeout packaging often contains fluorinated additives.

What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
PFAS
Unspecified coating on grease-resistant pulp containers frequently contains PFAS (perfluorinated compounds) to achieve water and oil repellency. Migration into fatty or hot foods is well documented in peer-reviewed studies, though no specific batch testing for this product is public.
Source, ATSDR ↗Chlorine-based bleach residues in pulp fiber
Conventional pulp bleaching uses chlorine dioxide or elemental chlorine, which can leave trace chlorinated organics (dioxins, chlorinated hydrocarbons) if process water is not fully treated. No recall history for this brand, but no disclosure of bleach source or residue limits.
Coating degradation and microparticle release
Grease-resistant coatings degrade over time, especially when exposed to heat, oils, or acid; peeling or flaking releases microscopic particles into food. Visual inspection before use is the only consumer-level control.
Microplastic or polymer fragments from coating wear
If the grease coating is synthetic polymer-based (Teflon-type coating, polyacrylate, or polyurethane), mechanical wear during handling or heating can generate fine particles that may be ingested with food.
What’s reassuring
Heavy metals
No contamination reports or FDA enforcement actions on record for Durable Packaging clamshells. Pulp-based containers carry lower risk of intentional heavy metal addition compared to ceramic or plastic containers.
Source, FDA ↗The full breakdown
What it's made of and why it matters
EcoQuality clamshells are molded food-grade pulp (likely bleached wood fiber) with an applied grease-resistant coating of unknown chemical composition. The coating is the critical unknown, manufacturers typically use either PFAS-based fluorochemicals (like Teflon-type coating or polyhydroxyalkanoates) or non-fluorinated alternatives (wax, clay, or plant-based polymers) to repel oils and moisture. Without disclosure, you cannot verify which family the coating belongs to, creating uncertainty about migration into fatty foods.
The brand's record and disclosure
Durable Packaging does not publicly disclose coating chemistry or PFAS content for this product line, nor are they known for third-party certifications (e.g., Cradle to Cradle, OK Compost) that would verify alternatives with lower concern. No recalls or contamination reports are on record for this specific product. The company's silence on ingredient sourcing is typical for commodity pulp packaging but limits your ability to make an informed choice.
How it compares in its category
Pulp clamshells dominate the compostable takeout market and generally carry lower chemical risk than polystyrene foam or plastic clamshells (which carry BPA or phthalate concerns). However, grease-resistant pulp containers vary widely, some use PFAS coatings, others use alternatives with lower concern for PFAS presence. This product sits in the mid-risk zone because the coating is unspecified; branded 'eco' claims do not guarantee PFAS-free formulation.
If you buy it
Use these containers for dry or room-temperature foods whenever possible; avoid prolonged contact with hot, fatty, or acidic foods, which increase coating migration risk. Replace containers if the interior surface shows visible wear, discoloration, or greasing through the fibers (signs of coating breakdown). Compost after single use if your facility accepts pulp; do not microwave or use for extended storage of oils or meats.
