Caraway Cream 6.6-Cup Non-Stick Glass Food Storage Container with Lid
Lower PFAS concern, glass container with stated non-PFAS lid, though third-party verification absent.
Caraway's glass food storage containers carry the brand's public commitment to avoiding PFAS in coatings and lids. The primary material (borosilicate glass) is inherently PFAS-free.
Brand says: “Caraway markets its products as PFAS-free and non-toxic; this container features glass with a BPA-free lid (typically silicone or polypropylene-based).”

Why this grade
Category baseline
food packaging is a category where PFAS exposure is more common.
Brand-stated PFAS-free
The brand states the product is PFAS-free (self-declared).
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
Caraway's container uses borosilicate glass, a heat-resistant silicate compound that does not leach chemicals into food at normal storage temperatures. The lid is stated to be non-PFAS, meaning it avoids the fluorinated compounds used in many competing non-stick food storage lids. Borosilicate glass is chemically inert and does not degrade when storing acidic, oily, or water-based foods over time, making it one of the safest container materials available for room-temperature and refrigerator use.
The brand's record and disclosure
Caraway has publicly committed to PFAS-free cookware and food storage as a core brand position, though third-party certification (such as SVHC or legal PFAS testing reports) has not been publicly disclosed for this specific container lid. The brand has faced no known recalls or regulatory warnings related to leaching or material degradation. Caraway's transparency about non-PFAS formulations is consistent with their cookware line, though consumers should note that 'non-PFAS' claims are not independently audited in publicly available databases.
How it compares in its category
Glass food storage containers are among the safest options available, with no known chemical leaching hazards. This product compares favorably to plastic alternatives (which carry BPA/BPS and phthalate risks, especially if heated) and ceramic-lined options (which may contain lead or cadmium in glazes). The non-PFAS lid sets it apart from many standard plastic food storage containers that use PFAS-based coatings; however, competing glass containers with silicone or standard polypropylene lids are similarly safe if PFAS-free.
If you buy it
Store only at room temperature or in the refrigerator; borosilicate glass is oven-safe but the plastic lid is not, so transfer contents to an oven-safe vessel if heating is needed. Inspect the lid regularly for cracks or wear, and replace if the seal degrades or the non-stick surface shows visible damage. Hand wash or use a gentle dishwasher cycle to avoid thermal shock. The glass itself will not degrade, but the lid's longevity depends on normal use without extreme temperature swings.
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.”
Lid material degradation over time
Caraway states the lid is non-PFAS, but the specific polymer composition and long-term durability of the lid material are not disclosed in public sources. Non-PFAS alternatives sometimes use less-established materials; monitor for visible wear, discoloration, or loss of seal integrity over 1-2 years of use.
Microplastics from lid shedding
No reports of microplastic shedding from Caraway lids exist in public databases. Borosilicate glass itself does not shed particles; risk would be limited to the lid material if it experiences mechanical damage or abrasion.
Thermal shock and glass breakage
Borosilicate glass is more resistant to thermal shock than standard glass, but rapid temperature changes (e.g., hot dishwasher to cold refrigerator) can still cause cracking. This is a physical hazard rather than a chemical one; follow manufacturer guidance on temperature transitions.
Lid seal integrity and bacterial growth
Any food storage lid can harbor bacteria if not cleaned thoroughly or if the seal is compromised. Caraway's lid design does not feature reported antimicrobial properties; standard dishwasher cleaning and visual inspection for seal damage are required for food safety.
Unlabeled lid polymer composition
While the lid is stated to be non-PFAS, the specific resin type (polypropylene, polyester, silicone, etc.) is not disclosed in publicly available product documentation. This limits independent assessment of potential leachates under edge-case conditions (e.g., acidic or oily foods stored long-term).
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 82% 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.
Formulations and coatings change between production runs. Always check the current label before buying.
