Huhtamaki Soup Food Containers w/Vented Lids
Avoid or contact Huhtamaki. Grease-resistant food containers often contain PFAS.
Huhtamaki soup containers use molded fiber with water and grease-resistant coating typical of food service ware. Such coatings historically contain PFAS, though Huhtamaki makes no public disclosure.

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
Molded fiber food containers with 'grease-resistant' coatings typically contain legacy PFAS formulations (PFOA, PFOS, or shorter-chain replacements). Hot or acidic foods like soups accelerate migration into the product. Huhtamaki has not disclosed coating chemistry or PFAS status.
Source: ATSDR ↗Thermal breakdown of coating
If accidentally heated (microwave exposure), fluorochemical coatings may degrade and release degradation byproducts into food. No data on this specific product is publicly available, but the risk exists for any PFAS-coated molded fiber used in hot service.
Microplastic and fiber shedding
Molded fiber containers can shed microscopic paper fibers and coating particles, especially if the interior coating is compromised or worn. This is more a durability and cleanliness concern than acute toxicity, but repeated use or rough handling increases shedding risk.
Coating adhesion loss over time
Molded fiber coatings (particularly PFAS-based) are known in industry literature to delaminate or peel with storage, moisture exposure, or repeated use cycles. Peeling coating can shed into food.
No independent food safety certification
The product does not carry public certifications (e.g., NSF, FDA premarket notification, or third-party PFAS testing). This is not proof of hazard but reflects lack of transparent safety assurance to consumers.
The full breakdown
What it's made of and why it matters
Huhtamaki Soup Food Containers use molded fiber (pressed paper pulp) as the base material, which is inherently compostable and food-safe. The critical component is the liquid repellent coating applied to the interior surface, which in this product class is almost certainly a fluorochemical (PFAS-based) formulation designed to prevent grease and moisture from penetrating the porous fiber. This coating directly contacts hot or warm food, creating a potential migration pathway for PFAS into liquids and semi-solid foods, especially soups where extended contact time increases leaching risk.
The brand's record and disclosure
Huhtamaki is a major global food packaging manufacturer but maintains public silence on PFAS content in their food containers and has not published commitments to phase out fluorochemical coatings. The company does not offer transparent ingredient disclosure or third-party certification for PFAS-free formulations on this product line. No major recalls or documented contamination incidents specific to this brand are on public record, but the absence of proactive communication about a known hazard in an industry under regulatory scrutiny is a transparency red flag.
How it compares in its category
Most disposable molded fiber food containers in the market contain PFAS-based water and grease repellent coatings, making this a category-wide issue rather than a Huhtamaki-specific failure. However, some manufacturers (such as Footprint and smaller eco-focused brands) now offer PFAS-free alternatives using plant-based or non-fluorinated repellent systems, though availability and cost vary regionally. Choosing uncoated fiber containers for dry foods or certified PFAS-free options for liquids shifts risk significantly lower.
If you buy it
Do not heat these containers in microwave or oven, as elevated temperature accelerates PFAS migration from the coating into food. Use only for room-temperature or briefly warm foods (under 40 degrees Celsius / 104 degrees Fahrenheit); soups should be transferred to ceramic or glass vessels before heating or cooling. Replace containers immediately if the interior coating shows peeling, discoloration, or visible wear, as degradation increases leachable material. Consider these a single-use product; do not reuse or wash and reuse, as this degrades the coating further.
