Rubbermaid Premier Food Storage Container 10 Piece Set
Lower-concern food storage; no PFAS risks typical of this polymer class, but no public brand commitment.
Rubbermaid Premier containers are polypropylene plastic, a common, non-fluorinated polymer not inherently formulated with PFAS. Food-storage containers of this type carry minimal legacy PFAS risk compared to nonstick cookware or water-resistant apparel.

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
Rubbermaid Premier containers are polypropylene (PP, plastic #5), a food-contact-grade thermoplastic chosen specifically for food storage because it resists degradation at moderate temperatures and does not leach BPA or similar estrogenic compounds. Polypropylene is one of the more chemically stable food-contact plastics; it does not hydrolyze readily and lacks the known endocrine-disrupting additives found in older polycarbonate formulations. The lids typically contain polypropylene or polyethylene (PE), with seals of elastomer or silicone, all materials with established safety profiles for cold and room-temperature food contact.
The brand's record and disclosure
Rubbermaid (owned by Newell Brands) does not publish detailed material safety datasheets or third-party certification claims on these containers. The brand has no known recalls specific to chemical leaching from Premier food-storage lines. Rubbermaid containers sold in North America comply with FDA food-contact regulations, but the company does not voluntarily disclose compliance testing or commit publicly to PFAS-free formulations across its product lines, a silence common among mainstream plastic manufacturers.
How it compares in its category
Polypropylene food-storage containers from mainstream brands (Rubbermaid, Tupperware, Glad, Lock & Lock) are considered chemically safer than older melamine or polycarbonate alternatives. Unlike glass containers, PP does not risk breakage; unlike uncoated metal, it does not corrode. Rubbermaid Premier sits in the mid-market tier: cheaper than specialty brands making explicit BPA/PFAS-free claims, but backed by decades of market presence and FDA compliance, making it materially equivalent to many competitor offerings.
If you buy it
Store cold and room-temperature foods only; avoid direct microwaving in the container (transfer to glass or ceramic) since repeated heating of polypropylene can accelerate aging of seals and closure mechanisms. Do not expose to oils, vinegar, or high-fat foods for extended periods, as PP can absorb lipophilic compounds over weeks. Wash by hand or on gentle dishwasher cycles; inspect seals annually for cracks or discoloration and replace if degraded. Expect practical lifetime of 3-5 years with regular use before seals lose integrity.
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.”
Microplastics migration under heating
Polypropylene is microwave-unsafe; repeated heating above 65°C (150°F) can accelerate polymer chain breakdown and potential particulate migration into food, though risk is low for cold storage use as intended.
Seal degradation and bacterial retention
Elastomer or silicone seals degrade over time and with repeated thermal cycling; worn seals can trap moisture and food residue, creating conditions for microbial colonization if containers are not fully dried after washing.
Additive leaching (UV stabilizers, antimicrobials)
No public reports of problematic additive migration from Rubbermaid Premier containers; polypropylene formulations are relatively stable, but brand does not disclose full additive lists or UV/antimicrobial stabilizer composition.
BPA or BPS contamination
Polypropylene does not inherently contain BPA; no recalls or warnings specific to estrogenic compound leaching from this product line. However, brand does not certify BPA-free status explicitly.
Staining and odor retention
Polypropylene can absorb odors and pigments from strongly colored or aromatic foods (e.g., turmeric, tomato sauce) over time; while not a chemical hazard, persistent staining may indicate surface degradation where residue can harbor pathogens.
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.
