Genpak Hinged Container 8 oz. AD08
Skip. Polystyrene food containers often treated with PFAS for grease resistance.
Genpak AD08 is a polystyrene hinged food container. No PFAS disclosure provided; grease-resistant polystyrene packaging commonly contains PFAS coatings. Safer alternatives include glass or ceramic.

The full breakdown
What it's made of and why it matters
Genpak AD08 is a hinged clamshell container molded from polystyrene (PS, #6 plastic). The "grease-resistant" marketing suggests a surface treatment, most likely fluorinated coating (PFAS-based), which is standard industry practice for food-contact polystyrene to prevent oil and moisture penetration. Polystyrene itself is brittle and degrades over time with UV, heat, and mechanical stress, but the primary concern here is what that coating contains.
The brand's record and disclosure
Genpak is a major foodservice packaging manufacturer but does not publicly disclose whether this product line uses PFAS-based grease treatments or alternatives. No major recalls or contamination incidents are on record for this specific SKU. The company has not published commitments to phase out PFAS in foodservice containers, unlike some competitors. This silence is typical for mid-tier packaging suppliers but represents a transparency gap.
How it compares in its category
Polystyrene hinged clamshells are among the cheapest foodservice options and widely used despite environmental and chemical concerns. Many competing brands (e.g., Eco-Products, Footprint) now offer molded fiber or cardboard hinged containers that avoid polystyrene and PFAS treatments altogether. For equivalent cost, compostable clamshells have become more available. Polystyrene clamshells remain common but are increasingly viewed as a legacy choice.
If you buy it
Do not heat food in these containers above 160-170°F (71-76°C), as polystyrene softens and may leach monomers. Keep away from direct sunlight and do not reuse for non-food storage. For temporary food storage only; do not rely on these for long-term or frequent reheating. Consider the likelihood that the grease-resistant coating contains PFAS before purchasing if food contact frequency is high or if you have dietary sensitivity to fluorinated compounds.
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.”
BPA and polystyrene monomers (styrene leaching)
Polystyrene itself does not contain BPA, but can leach residual styrene monomer and oligomers, especially when exposed to heat, acidic foods, or fats. This container's brief food-contact window (hinged clamshell for takeout) limits exposure, but single-use heat exposure (warm foods) poses measurable risk.
Microplastics from degradation
Polystyrene is brittle and fragments under mechanical stress or UV exposure. While the AD08 is a single-use item, fragments can enter food if the lid is cracked or material degrades before disposal.
Fluorinated coating leachates (PFAS alternative or PFAS itself)
Genpak does not disclose the identity of its grease-resistant treatment. Industry standard for polystyrene clamshells is Teflon-type coating or PFOA-related coatings, but some manufacturers have switched to fluorine-free alternatives. Without disclosure, assume traditional PFAS-based treatment is possible.
Heat-induced softening and monomer release
Polystyrene containers are documented to soften and release styrene at temperatures above 160°F. Warm soups, gravies, or heated bakery items can trigger leaching. This product's use in foodservice (typically 120-160°F foods) keeps risk in the moderate range but does not eliminate it.
None known - phthalates
Polystyrene is not typically formulated with phthalate plasticizers. Phthalate risk is minimal for this material class.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 42% 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.
