Good Grips POP Food Storage Container
Lower concern for a basic rigid plastic food container, but lack of material transparency is a minor red flag.
Good Grips POP containers are standard rigid plastic food storage, likely polypropylene or similar base polymers, which don't inherently contain PFAS. The brand provides no explicit PFAS disclosure or certification, which is common for basic food containers.

The full breakdown
What it's made of and why it matters
Good Grips POP containers are rigid polypropylene (PP), a thermoplastic polymer chosen for food contact because it resists leaching under normal conditions. Polypropylene has no inherent BPA or phthalate additives in its base formula, though some manufacturers add plasticizers or UV stabilizers whose composition is rarely disclosed on packaging. The 'airtight' seal likely relies on a rubber or silicone gasket; these materials can degrade over time and should be inspected for cracks or discoloration. The plastic itself is inert in cold and room-temperature storage but can soften or leach additives if exposed to heat above 100-110°C (boiling water or dishwasher heat cycles).
The brand's record and disclosure
Airtight is a lesser-known brand in the rigid food container space and maintains minimal public transparency on material sourcing, additive content, or third-party testing. No major recalls or safety controversies are documented in public databases for this specific product line. The brand does not publish material safety data sheets (SDS) or PFOA/PFAS declarations on its consumer website, which is typical for budget-tier container makers but leaves end-users without confirmation of manufacturing standards. No BPA-free or certification claims (such as FDA compliance statements) are prominently advertised.
How it compares in its category
Polypropylene rigid containers occupy the middle ground of food storage safety: they are chemically more stable than thin flexible plastics (like PVC cling film) and equivalent to or slightly less transparent than glass. Major brands (OXO, Rubbermaid, Sistema) offer similar PP containers but with documented FDA compliance statements and more detailed material labeling. The Airtight brand's lack of public accountability makes direct comparison difficult; it likely meets baseline US food contact regulations, but offers fewer assurances than premium competitors. Price positioning suggests this targets budget-conscious buyers; durability and gasket longevity are unknowns without long-term user reviews.
If you buy it
Avoid filling these containers with hot or boiling food or liquid; cool to room temperature first to prevent leaching of additives and gasket degradation. Hand-wash rather than dishwasher-wash to extend gasket life and reduce thermal stress on the plastic. Replace the container or gasket if you notice cloudiness, cracking, persistent odors, or a loose seal, typically after 2-3 years of regular use. Store in cool, dark places away from direct sunlight to slow UV-induced brittleness; do not use for long-term storage of acidic foods (vinegar, citrus) or oils, which can soften PP over months.
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 and plasticizer leaching
Polypropylene base resin does not contain BPA, but unknown additives used to improve flexibility or UV resistance may include bisphenol compounds or phthalates. No independent testing of this specific brand is publicly available; risk is low under cold/room-temperature storage but increases with heat exposure or storage of fatty/oily foods.
Microplastics when heated
If food or liquid stored in this container is heated above 100-110°C (e.g., reheating in a dishwasher or accidentally on a stove), the PP can soften and potentially release microplastic particles. This is primarily a concern if containers are repeatedly heated or if gaskets degrade and fragment.
Gasket/seal degradation
The rubber or silicone gasket is the weak point in long-term safety and seal integrity. Over time, gaskets may develop cracks, shrinkage, or mold growth if not cleaned properly, compromising airtightness and potentially allowing odor absorption or microbial contamination. Brand-specific gasket longevity data is not published.
Material transparency and additive disclosure
Airtight brand does not publicly disclose the specific additives, stabilizers, or processing aids used in manufacturing, which is a minor red flag for consumer safety assessment. This is a category-wide issue for budget brands; it does not indicate a known hazard but reflects lack of third-party accountability.
Odor and stain absorption
Polypropylene is slightly porous and can absorb strong odors and fat-soluble stains (tomato sauce, curry) over time, though this is cosmetic rather than a chemical safety issue. Persistent odors may indicate partial polymer degradation or microbial colonization in scratches.
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.
