Rubbermaid Klip It Lunch Food Storage Container
Lower PFAS concern, rigid PP food storage is not a typical PFAS risk category, but verify if any gasket/seal coatings are disclosed.
Rubbermaid Klip It containers are rigid polypropylene, a plastic type not commonly treated with PFAS. The brand makes no PFAS claims and no lab data is publicly available for this product. The main uncertainty is whether gaskets or lid seals contain any water-resistant coatings; if present and undisclosed, they warrant caution.

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 Klip It containers are polypropylene (PP, #5 plastic), a rigid, heat-stable polymer that does not contain BPA or phthalates by design. PP has a melting point around 130°C (266°F) and is recognized as one of the safer food-contact plastics because it resists leaching at typical use temperatures. The main concern with PP is degradation if repeatedly heated near or above its limit, or if exposed to aggressive solvents or high-fat foods at elevated temperatures, which can cause microcracking and potential microplastic release.
The brand's record and disclosure
Rubbermaid (owned by Newell) does not publicly disclose PFAS-free certification or detailed material sourcing for this product line. The brand has not faced major product recalls or legal actions tied to chemical contamination in rigid food storage. However, the lack of proactive transparency about gasket coatings, colorants, or manufacturing processes means verification of non-PFAS additives is not available on the product label or official website.
How it compares in its category
Klip It containers are mid-range in the rigid PP food storage market. They perform similarly to Snapware and Pyrex glass alternatives in terms of base material safety, but Pyrex offers transparency advantage (borosilicate glass, no plastic leaching concerns). Compared to lower-cost grocery-store PP containers, Rubbermaid's build quality and lid closure reduce the risk of repeated microcracking. Higher-end alternatives like Glaslock or Caraway offer glass construction with full ingredient disclosure, but at 2-3x the price.
If you buy it
Store cold and room-temperature foods; do not microwave these containers (lids and seals are not microwave-rated). Hand-wash or use cooler dishwasher cycles to avoid thermal stress to the plastic. Replace lids if they become cloudy, brittle, or fail to seal properly, as seal integrity is critical to prevent moisture ingress and mold growth. Keep away from oils, vinegar, and acidic foods at warm temperatures, as these can accelerate minor leaching.
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.”
Microplastic release from thermal or mechanical degradation
PP containers can shed microplastics if heated repeatedly above 70°C (158°F), microwaved, or subjected to scratches and wear. Rubbermaid Klip It lids are not microwave-safe, reducing this risk under normal use, but prolonged hot-water washing or dishwasher heat cycles may accelerate lid degradation over years.
BPA or BPS in colorants or additives
Polypropylene itself does not require BPA or BPS as plasticizers. No recalls or testing data suggest BPA contamination in Klip It products. However, brand does not certify BPA-free on packaging, leaving a minor verification gap.
Phthalates in plastic formulation
PP rigid containers do not rely on phthalates for flexibility. No public testing or recalls indicate phthalate content in Rubbermaid's rigid food storage line.
Gasket or seal coating leachables (unknown composition)
Klip It lids use rubber or synthetic gasket seals; Rubbermaid does not disclose the material or treatment of these seals. Seals could theoretically harbor PFAS-based water repellents or other additives, but no testing or complaints are on record for this product.
Mold or bacterial growth if seals weaken
If lid seals fail or become porous, containers may trap moisture and encourage mold or bacterial colonization. This is a maintenance issue, not a material hazard, but relevant to long-term 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.
