Rubbermaid Premier 20-Piece Food Storage Set

C · Moderate

Lower PFAS risk for rigid food storage; verify lid material independently.

Verdict: BuyPolypropylene food storage with no established hazard record; lower leaching risk at typical use; verify lid seals over time.

Rubbermaid Premier food storage sets use polypropylene plastic, a commodity resin without intentional PFAS additives in standard formulations. However, Rubbermaid makes no public PFAS disclosure.

The full breakdown

What it's made of and why it matters

Rubbermaid Premier containers are rigid polypropylene (PP, #5 plastic), one of the safer food-contact plastics with no BPA or phthalates intentionally added. PP does not leach harmful chemicals under normal cold and room-temperature storage; the plastic is inherently stable and approved by FDA for food contact. Lids are typically PP or a PP-elastomer blend; lid degradation or seal failure over years of use is a wear concern, not a chemical one.

The brand's record and disclosure

Rubbermaid (owned by Newell Brands) does not publicly disclose detailed chemical content or third-party safety testing for this product line. The brand has no widely documented recalls or health controversies tied to Premier food-storage containers specifically. Rubbermaid is not known for aggressive transparency on PFAS or phthalate phase-out, but also has no pattern of non-compliance with US food-contact regulations.

How it compares in its category

PP rigid containers are considered mid-range for safety among food-storage options. Glass alternatives (Pyrex, Anchor Hocking) eliminate all plastic leaching risk but cost more and break easily. Other PP brands (Glad, Sistema, Pyrex Premiere) are broadly comparable; Rubbermaid's main differentiator is durability reputation, not chemical safety. BPA-free and phthalate-free claims are industry standard now and not a competitive advantage.

If you buy it

Store cold and room-temperature foods only; do not microwave in these containers (check lid manufacturer guidance separately). Replace lids every 3-5 years or when seals no longer hold tight, as wear is the primary failure mode. Hand-wash or top-rack dishwasher only; avoid harsh scouring that may degrade plastic surface. Keep away from direct sunlight and heat sources, which accelerate minor polymer degradation over decades.

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.”

None known

BPA/BPS and phthalates

Polypropylene (#5) is not manufactured with BPA or common phthalates; no such contamination is documented in Rubbermaid Premier containers. Regulatory food-contact approval implies absence of intentional addition.

Possible

Microplastics from container degradation

Mechanical wear (scratches, abrasion) or photodegradation over many years can shed microscopic particles, but this is typical for all rigid plastic food storage and is not specific to Rubbermaid's formulation. Risk is minimal with proper care and periodic replacement.

Possible

Leaching from lid seals and gaskets

Lid elastomers (often silicone or rubber blends) may contain trace contaminants or off-gas compounds, especially if lids are old or exposed to heat. Rubbermaid does not publish lid material composition. This is a general concern for any plastic food-storage system with removable lids, not unique to this brand.

Possible

Mold or bacterial growth in lid crevices

Rubbermaid Premier lids have multiple sealing ridges that trap moisture and food particles if not cleaned thoroughly. This is a maintenance issue, not an inherent material hazard, but improper washing creates a microbial risk.

None known

Chemical migration from prolonged high-temperature exposure

PP containers are not meant for hot food or dishwasher heat cycles; Rubbermaid Premier is labeled for cold storage. No leaching incidents are documented at intended-use temperatures. Misuse (boiling water, oven) could theoretically accelerate minor degradation but is outside design scope.

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.
