Good Grips POP Food Storage Container
Lower concern, rigid plastic food storage typically avoids PFAS, but OXO provides no public statement.
OXO's POP containers are rigid polypropylene plastic with plastic snap-lids, a category with lower inherent PFAS risk compared to nonstick cookware or water-resistant coatings. OXO does not publicly disclose PFAS content or commitments. No independent lab data or third-party certification is publicly available for 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
Good Grips POP containers are rigid polypropylene (PP, #5 plastic) with polypropylene snap lids. Polypropylene is a relatively inert, non-leaching plastic at normal refrigerator and room temperatures, with a melting point around 167°C. Unlike softer plastics like PVC or polycarbonate, PP does not contain bisphenols (BPA/BPS) or phthalate plasticizers in its base formulation. The rigid structure and snap-closure design minimize edge degradation compared to flexible storage bags.
The brand's record and disclosure
OXO has published a chemical policy addressing restricted substances and maintains informal third-party certifications through supply-chain audits, though formal independent testing data is not publicly disclosed for this specific SKU. The brand has no documented recalls or safety violations related to food storage toxicants in recent years. OXO does not publish a dedicated PFAS transparency statement, consistent with many housewares manufacturers who treat PFAS as a non-issue in rigid plastic food storage.
How it compares in its category
Polypropylene rigid containers occupy the safety middle ground in food storage: safer than older polycarbonate or PVC alternatives, equivalent to glass in toxicant risk, but less durable than glass. OXO's engineering (vented lids, stackability) is standard for the mid-market segment. Competitive products (Rubbermaid, Pyrex, Sistema) use identical or similar PP formulations with equivalent risk profiles.
If you buy it
Keep containers out of direct heat sources and do not microwave filled containers at high power; warm water (not boiling) is safe. Replace lids if cracked or warped, as degraded seals allow odor absorption but not leaching risk. Hand-wash rather than dishwasher if longevity is a priority, though dishwasher exposure does not pose acute toxicant release. Store acidic foods (tomato sauce, citrus) briefly; while PP is stable, extended acidic contact may slightly soften older or thin-walled lids over years.
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 formulations do not use bisphenol monomers. No BPA or BPS is present in the base plastic or typical additives for food-contact PP.
Phthalate plasticizers
Rigid polypropylene does not require phthalate softeners. OXO does not disclose additive packages, but phthalates are not standard in PP food-storage production.
Microplastic shedding
Normal mechanical wear of snaps and repeated lid flexing can generate PP microparticles over years, especially if frozen/thawed or dishwashed repeatedly. Frequency is low under typical use and risk to consumers is considered negligible.
Lid degradation and odor/stain trapping
Polypropylene lids are prone to softening, warping, and permanent staining/odor absorption after repeated hot dishwashing or prolonged use with strong-smelling foods. This is a durability issue, not a toxicant release risk.
Off-gassing (VOCs)
Polypropylene has minimal volatile organic compound emissions at room and refrigerated temperatures. No formaldehyde-release resins are used in rigid PP formulations.
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.
