Corelle Brands Snapware Total Solution Pyrex Glass Storage Container
Lower-concern choice; glass is inherently PFAS-free, but lid composition unclear.
This product pairs borosilicate glass containers, a material with no known PFAS risk, with plastic lids of unspecified composition. While the glass container itself presents lower concern, Snapware makes no public disclosure about PFAS in the lids.

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.
Uncoated safe material
Bare, uncoated material (cast iron, stainless, carbon steel, or glass) with no surface treatment to contain PFAS.
The full breakdown
What it's made of and why it matters
This product combines borosilicate glass (the container body) with a plastic lid assembly. Borosilicate glass is chemically inert, does not leach into food, and resists thermal shock better than standard soda-lime glass, making it suitable for oven and microwave use up to the manufacturer's stated temperature limits. The plastic lid is the variable component; Snapware has not publicly disclosed lid material composition (polypropylene vs. other polymers) or whether it contains BPA or similar plasticizers, which is a common gap in industry transparency for this product class.
The brand's record and disclosure
Snapware (owned by Newell Brands) does not publish detailed material safety data or third-party certifications for this specific container line. The brand has no widely documented safety recalls specific to chemical leaching from these glass containers, and no public stance on PFAS avoidance or BPA-free claims for lids. This silence is typical for major food storage manufacturers but limits independent verification of lid safety.
How it compares in its category
Glass storage containers are among the lowest-risk options in the food storage category because glass itself does not leach. Snapware's borosilicate formulation is comparable to Pyrex-branded containers and similar mid-tier offerings. Most competitors in this price range also leave plastic lid composition undisclosed, making this product neither notably safer nor riskier than equivalent glass container sets from OXO, Anchor Hocking, or store brands.
If you buy it
Do not microwave the lid itself; remove it before heating food. Avoid exposing lids to prolonged heat above 160-180°F, as plastic components may degrade and release compounds into food. Replace lids if they become discolored, cracked, or develop odors. Wash lids by hand rather than in high-temperature dishwasher cycles to extend their lifespan and reduce leaching risk. Store acidic foods (tomato sauce, citrus) in glass containers only, as plastic lids may absorb flavors or compounds over time.
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.”
Plastic lid composition and leachables (BPA, phthalates)
Snapware does not publicly disclose whether lids contain BPA or phthalate plasticizers. Standard polypropylene lids are generally low-risk, but without manufacturer confirmation, exposure risk cannot be ruled out, especially if lids contact hot or fatty foods.
Lid degradation over time
User reports and product reviews note that Snapware lids can develop cloudiness, cracks, or odor retention after extended use. Degraded plastic may increase leaching risk; replacement of worn lids is advisable.
Borosilicate glass thermal shock
No safety issues documented with borosilicate glass itself under normal use. Thermal shock (rapid temperature change) can crack the glass but poses no chemical hazard. Avoid placing frozen containers directly on hot stove surfaces.
Microwave safety of plastic lids
Lids are not rated for microwave use by Snapware. Heating lids in microwave may accelerate plastic degradation and increase leaching; removing lids before microwaving is necessary.
Dyes or pigments in lid seals or gaskets
No public reports of heavy metal contamination in Snapware container gaskets or seals. Most manufacturers in this category use food-grade silicone or rubber, but composition remains undisclosed for this brand.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 85% 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.
