Rubbermaid Premier Food Storage Containers with Easy Find Lids (20-Piece Set)
Lower PFAS concern for basic food storage, but Rubbermaid offers no transparency on manufacturing processes.
Rubbermaid Premier containers are made from polypropylene plastic, a material not inherently associated with PFAS in typical food storage applications. The brand does not disclose PFAS practices or claim PFAS-free status.

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
These containers are polypropylene (PP), a thermoplastic polymer rated food-safe by FDA for temperatures up to around 100-120°C (212-248°F). PP is one of the more chemically inert plastics for food contact because it does not contain BPA, BPS, or phthalates by design. However, the integrity of any plastic depends on the quality of additives (colorants, stabilizers, impact modifiers) used during manufacturing, which Rubbermaid does not publicly disclose in detail.
The brand's record and disclosure
Rubbermaid (owned by Newell Brands) has no major food-storage-related recalls in recent public records for this product line and maintains FDA compliance statements. The company does not publish detailed materials disclosure documents, third-party certifications (such as BPA-free labeling), or manufacturing process transparency beyond standard claims. No independent toxicity controversies specific to this product series are documented in consumer safety databases.
How it compares in its category
Polypropylene is mid-range for food storage: safer than older polycarbonate or melamine products, but less transparent than glass or stainless steel alternatives. Rubbermaid Premier sits at the commercial-grade end of the PP market; its main advantage is durability and price, not material innovation. Competitors like OXO and Pyrex offer similar PP options or glass upgrades, with slightly better labeling practices.
If you buy it
Never microwave these containers (PP warps above 100-120°C and may release unstable additives); hand-wash or use the top-rack dishwasher cycle only. Replace containers if lids become cloudy, brittle, or discolored, as this signals polymer degradation. Store acidic foods (tomato sauce, citrus, vinegar) in glass instead, as acidity can leach additives from plastic over time. Inspect for cracks or surface damage before first use, as manufacturing defects can expose users to fill material or adhesives.
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 and phthalates
Polypropylene is chemically formulated without BPA or phthalates by material class. No recalls or testing failures are on record for Rubbermaid Premier containers in this category.
Microplastics from heating or degradation
Heating PP above its glass transition temperature (around 100-120°C) or repeated thermal cycling can cause shedding of polymeric particles. Microwaving is the primary risk; dishwasher high-heat cycles may accelerate lid degradation over years of use.
Additive leaching (colorants, stabilizers, flame retardants)
Rubbermaid does not disclose the specific additives used in these containers. Prolonged contact with acidic or fatty foods can promote leaching of UV stabilizers or processing aids, though risk is low under normal storage conditions (room temperature, neutral to mildly acidic foods).
Coating or lid adhesive contamination
No documented issues with adhesives in the Easy Find Lid system. However, manufacturing defects in lid seals could theoretically expose consumers to uncured epoxy or cyanoacrylate residue; visual inspection at purchase mitigates this.
Bacterial growth from improper sealing or maintenance
If lids do not seal properly (common wear issue in 20-piece sets with multiple lids), trapped moisture can promote mold or bacterial growth inside the container. Regular inspection and replacement of warped lids is essential for food safety.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% 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.
