Rubbermaid Premier Food Storage Container 3 Cup Grey 4 Pack
Lower-concern food storage; rigid plastic containers rarely need PFAS, but Rubbermaid hasn't publicly disclosed their PFAS stance.
Rubbermaid Premier containers are rigid polypropylene food storage, a commodity plastic category with lower inherent PFAS risk compared to coated cookware or grease-resistant coatings. No public PFAS claim or third-party verification from Rubbermaid exists.

Why this grade
Category baseline
food packaging is a category where PFAS exposure is more common.
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
Rubbermaid Premier containers are polypropylene (PP), a thermoplastic chosen for food storage because it is more chemically stable than softer plastics like PVC or low-density polyethylene. Polypropylene does not leach BPA or phthalates under normal conditions; these additives are not required in rigid PP formulations. The snap-seal lid is also typically polypropylene or a similar food-grade plastic, designed to minimize air exchange and reduce migration risk.
The brand's record and disclosure
Rubbermaid (owned by Newell Brands) does not publish detailed PFAS or chemical composition transparency reports for consumer food storage lines. The brand has no documented recalls or safety findings specific to the Premier food storage line. Rubbermaid products generally meet FDA food contact standards, but the company has not publicly committed to PFAS-free manufacturing or third-party chemical disclosure, leaving some uncertainty about non-intentional PFAS contamination.
How it compares in its category
Polypropylene containers sit in the middle of the food storage spectrum: safer than flexible plastics (which leach more readily) but with less transparency than premium brands like Pyrex or stainless steel alternatives. Rubbermaid Premier is positioned as mid-tier; competitors like OXO and Sistema offer similar polypropylene options with marginal differences in design and durability. Rival glass containers eliminate plastic leaching entirely but break more easily and cost more.
If you buy it
Keep containers away from direct heat above 200 degrees Fahrenheit (polypropylene's safe limit is around 200-220F); do not microwave on high heat repeatedly or store hot foods. Inspect the seal and container walls regularly for cracks, cloudiness, or warping; replace every 2-3 years or sooner if damage appears. Hand-wash when possible; dishwasher cycles may gradually degrade the lid seals over time. Store in a cool, dark place away from direct sunlight to slow plastic 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 typically contain BPA or BPS, and no reports exist of these chemicals migrating from Rubbermaid Premier containers into food.
Phthalate plasticizers
Rigid polypropylene formulations do not require phthalates; none are known to be present in this product line based on available materials data.
Microplastics shedding during use
Repeated heating, thermal stress, or mechanical wear (scratches, stacking) can cause microscopic PP particles to migrate into food; risk increases with age and improper care. This is a general concern for all rigid plastic food storage, not specific to Rubbermaid.
Coating or lid degradation over time
Snap-seal lids on polypropylene containers may lose elasticity, crack, or cloud with repeated washing and thermal cycling, though this is a durability rather than acute toxicity issue.
Mold or bacterial growth in seals
Food residue trapped in lid grooves or seal channels can harbor bacteria if containers are not dried thoroughly after washing; this is a hygiene issue independent of material chemistry.
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.
