Amazon Essentials Case-Mate Waterproof 2L Dry Bag With Built-In Phone Pouch Phone Pouch With Strap
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes vinyl/PVC, with no water-repellent coating named. Water resistance on products like this usually comes from the material and its seals rather than a surface treatment. The brand has published no PFAS statement for it.

What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Microplastics
Over many years of UV exposure or mechanical stress, vinyl can fragment into fine particles. Risk is low during normal use as a protective case but increases if the material is creased repeatedly or stored in direct sunlight for extended periods.
Source, EPA ↗Bacterial or mold growth in sealed compartment
Waterproof sealing traps moisture if the bag is closed while wet inside. Risk is low if contents are dry and air circulation is adequate. Rinse and fully dry before sealing for extended storage; store in a cool, dry place to prevent microbial growth on trapped organic material.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
BPA & bisphenols
PVC dry bags are not typically treated with phthalate plasticizers; modern rigid vinyl used for waterproof cases relies on the polymer backbone alone. No leaching into food, skin, or water has been documented for this product class at room temperature.
Source, FDA ↗Volatile organic compound (VOC) off-gassing
Cured vinyl is not a significant VOC source at room temperature. Any odor on opening is residual from manufacturing and dissipates within days. No formaldehyde or solvent release has been reported for dry bag products in this category.
Heavy metals
Case-Mate dry bags typically use carbon black or standard organic dyes, not cadmium or lead-based pigments. No recalls or positive test results for heavy metals in Case-Mate cases are on public record.
Source, FDA ↗The full breakdown
What it's made of and why it matters
This dry bag is constructed from vinyl (PVC), a rigid, sealed polymer chosen for water resistance through material density and mechanical seals, not surface treatments. PVC itself is chemically inert when cured and does not leach plasticizers into air or skin during normal use at room temperature. The waterproof integrity comes from the welded or heat-sealed seams and roll-top closure, not a separate coating that could degrade.
The brand's record and disclosure
Case-Mate is a consumer electronics accessories brand owned by Incipio Group; no major chemical safety recalls or certifications are on public record for their dry bags. The brand does not publish materials safety data or PFAS statements, which is typical for low-risk commodity cases. No third-party testing of Case-Mate dry bags for leachables or off-gassing has been widely published.
How it compares in its category
Vinyl dry bags are standard in the market and fabric alternatives treated with water-repellent coatings may be linked to PFAS or formaldehyde concerns. Unlike silicone or rubber variants, PVC does not off-gas significantly at room temperature. This product sits in the middle tier, functional and non-toxic, but without premium material certifications (e.g., eco-labels or third-party testing) that some competitors offer.
If you buy it
Store at room temperature away from direct sunlight to prevent vinyl brittleness over years of storage. Do not expose to sustained heat above 60 degrees Celsius (140 Fahrenheit); do not leave in hot cars. Inspect seams and closures annually for wear; replace if cracks appear or seal no longer holds water. Rinse and air-dry after use in saltwater or chlorinated pools to extend life.
