Snapware 10 Piece Airtight Plastic Food Storage Bowl Set
Lower PFAS concern for storage-only use; plastic bowls themselves typically PFAS-free, but brand transparency absent.
Snapware's standard plastic food storage containers are made from polypropylene, a material not typically treated with PFAS in manufacturing. However, Snapware provides no public PFAS disclosure or third-party certification.

Why this grade

No PFAS disclosure
No public statement about PFAS in this product.
Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
Snapware bowls are polypropylene (PP, plastic #5), a thermoplastic polymer chosen for food storage because it does not leach BPA, BPS, or phthalates under normal non-heating conditions. PP is microwave-safe at low power and does not degrade significantly when storing food at room temperature or refrigerated. The snap-on lids are also PP, which means the entire system remains chemically inert during typical use (storing leftovers, dry goods, or cold items).
The brand's record and disclosure
Snapware is a subsidiary of Newell Brands and has no documented recalls or safety controversies related to chemical leaching or material degradation. The brand does not publicly disclose detailed material sourcing, manufacturing standards, or third-party testing; this silence is common in the food storage category but limits independent verification. No certifications (such as BPA-free statements or food-grade compliance badges) are widely advertised, though PP itself is FDA-cleared for food contact.
How it compares in its category
Snapware is a mainstream mid-range option; competitors like Rubbermaid, OXO, and Pyrex offer similar PP or glass alternatives at comparable prices. Glass containers avoid plastic concerns entirely but are heavier and breakable. PP containers from any major brand carry the same low chemical leaching risk; Snapware's main differentiator is snap-closure durability, not safety. No major independent testing has flagged Snapware as riskier than peer products.
If you buy it
Store cold or room-temperature food only; avoid microwaving at high power or storing hot liquids, as sustained heat can degrade the plastic and marginally increase leaching risk. Replace lids every 2-3 years if snaps become loose or cracked, as damaged seals compromise airtightness and allow air exposure. Wash by hand or top-rack dishwasher in cool cycles; abrasive scouring can cause surface wear. Do not use for long-term storage of fatty or acidic foods (oils, vinegars, citrus) at room temperature, as these can slightly accelerate polymer degradation.
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/BPS leaching
Polypropylene does not contain BPA or BPS; these chemicals are not part of PP formulation. Risk is not applicable to this material class.
Phthalate migration
PP does not use phthalates as plasticizers. Risk is not applicable to polypropylene food containers.
Microplastic shedding from wear
All plastic food containers shed trace microplastics over time, especially if abraded by utensils or dishwashers. The risk is present but minor for storage-only use and increases only if containers are scratched or used for high-temperature applications.
Lid degradation and seal failure
Consumer reviews mention snap mechanisms loosening after 1-2 years of frequent opening/closing, reducing airtight integrity. This is a durability issue, not a chemical safety hazard, but compromised seals can allow air exposure and moisture infiltration.
Leaching from ink or colorants on exterior
No documented cases of ink or dye migration from Snapware container exteriors into food. PP itself does not absorb or transfer dyes into stored contents under normal use.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 78% 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.
