Plano Waterproof Storage Case
Waterproof storage; coating composition undisclosed, raises PFAS concern.
Plano does not disclose waterproof coating materials or PFAS status. Waterproof plastic cases commonly use water-repellent coating treatments that may contain PFAS; contact brand for specifics.

The full breakdown
What it's made of and why it matters
Plano Waterproof Storage Cases are constructed from polypropylene (PP) or polyethylene (PE) plastic with an applied waterproof coating. Polypropylene itself is considered a safer plastic for food and non-food storage, with no established leaching of bisphenols or phthalates under normal use. The critical unknown is the waterproof coating formulation: most durable water-barrier coatings rely on fluorinated compounds (PFAS) to achieve hydrophobic properties, though some manufacturers now use silicone or wax-based alternatives. Plano has not publicly disclosed the coating chemistry, which is the primary safety concern for this product.
The brand's record and disclosure
Plano Molding is a US-based manufacturer known for fishing and storage products with a long market history, but has not adopted publicly visible PFAS reduction commitments or material transparency initiatives comparable to brands like Hydro Flask or OtterBox. No major recalls or documented contamination incidents are on record for Plano storage cases. The company does not provide material safety data sheets (MSDS) or coating composition details on consumer product pages, which is a transparency gap for a product explicitly marketed as 'waterproof.'
How it compares in its category
Hard polypropylene storage cases are common across brands (Plano, Pelican, Stanley); most achieve waterproofing via coatings or gasket-seal systems rather than material choice. Pelican cases, which compete directly, are similarly opaque on coating composition but carry military/professional certifications that imply testing rigor. Plano's consumer-grade positioning and lower price point suggest less rigorous chemical screening. For budget waterproof storage, this product is typical in its hazard profile but worse in disclosure.
If you buy it
Store dry goods, electronics, or outdoor gear rather than food or items intended for child contact. Do not expose to prolonged heat above 140°F (60°C), as PP begins to soften and any coating degradation accelerates chemical release. Inspect gaskets and seams annually for wear; replace the case if cracks or white stress marks appear, indicating polymer degradation. Avoid dishwasher cleaning; rinse with cool water and air-dry to minimize coating stress and leaching risk.
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.”
Waterproof coating composition (fluorinated or non-fluorinated)
Undisclosed coating is the primary concern. If fluorinated (likely for cost/performance), PFAS leaching into stored liquids or high-humidity environments is a known risk; non-fluorinated coatings are available but require manufacturer confirmation.
Polypropylene degradation and secondary leaching
Polypropylene is chemically stable under normal storage conditions. No BPA, BPS, or phthalate concerns are established for PP-based cases. Risk rises only if coating degrades, exposing underlying polymer to moisture or heat stress.
Microplastics from wear and tear
Hard PP cases can shed micro-fragments if gaskets or internal surfaces are abraded. Risk is low for dry-good storage but increases if case is heavily used, dropped, or scratched; particles could contaminate food or water if stored items contact case interior.
Gasket and seal material toxicity
Gaskets are typically silicone or rubber. No hazard is documented for standard gasket materials in storage-case applications, provided they are not heated or exposed to solvents.
Off-gassing from adhesives or sealants
New cases may emit mild plastic odors (volatile organics) for 1-2 days. This is cosmetic and resolves quickly. No formaldehyde or persistent VOC concern is documented for Plano cases, but airing outdoors for 24 hours before use minimizes exposure.
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.
