Case Mate Waterproof Floating Pouch
Waterproof pouch coating unknown; skip if PFAS-concerned.
Case Mate does not disclose the waterproof treatment chemistry. Waterproof coatings often contain PFAS, but no public lab testing or PFAS claims found for this product.

The full breakdown
What it's made of and why it matters
Case-Mate Waterproof Floating Pouches use TPU (thermoplastic polyurethane) as the base material, a flexible polymer chosen for water resistance and durability in wet conditions. The waterproof coating applied to this TPU is not disclosed in public specifications, making it impossible to rule out problematic additives. TPU itself is considered safer than PVC for food-adjacent use, but the unidentified surface treatment introduces a gap in the safety picture.
The brand's record and disclosure
Google/Case-Mate does not publish detailed material safety disclosures or ingredient transparency for this accessory line. No independent certifications (such as Oeko-Tex or FDA compliance claims) appear in available product documentation. The brand has not publicly addressed PFAS use in waterproof coatings, which is a significant omission given widespread industry reliance on fluorinated water-repellents.
How it compares in its category
Waterproof pouches vary widely in coating strategy: some use silicone-based water barriers (lower concern), others rely on fluorinated polymers or PFAS-containing treatments (higher concern). This product sits in the middle of the transparency spectrum, offering no clear advantage over competitors that explicitly state PFAS-free status or natural coatings. Budget alternatives and premium eco-focused brands often provide better disclosure.
If you buy it
Use the pouch for phones, keys, and documents in wet environments, not for prolonged food storage. Avoid exposing it to direct heat (sun-baking, oven) which can degrade TPU and any coating. Inspect regularly for peeling or cracking of the waterproof layer; replace if compromised. Rinse with fresh water after saltwater or chlorine exposure to extend life.
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.”
Unspecified waterproof coating composition
The waterproof treatment is not publicly identified; it may contain fluorochemicals, silicones, or other polymers. Without disclosure, potential leaching into stored items cannot be ruled out.
TPU polymer degradation under heat or UV
TPU can degrade, plasticize, or off-gas volatile organic compounds when exposed to sustained heat or direct sunlight, particularly if the waterproof coating begins to fail and expose the base material.
Microplastic shedding during use
As TPU ages or the coating fragments, microscopic polymer particles may shed into stored contents, especially if the pouch is flexed repeatedly or contents are damp.
Bacterial or mold growth if not dried
Waterproof pouches trap moisture; if sealed while damp or stored in humid conditions, internal surfaces can harbor microorganisms. This is a maintenance issue, not a material defect, but relevant to safe use.
Lack of food-contact certification
The pouch is not marketed for food storage and carries no FDA or equivalent clearance for indirect food contact; using it to store food or drinking vessels carries unknown risk from coating leachables.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 45% 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.
