Guide Series Waterproof Case 3600
Skip until Plano discloses waterproof treatment chemistry.
Plano's Guide Series 3600 is a waterproof storage case with unknown protective coatings. No PFAS disclosure or third-party testing publicly available; waterproof treatments often contain PFAS.

The full breakdown
What it's made of and why it matters
The Guide Series 3600 is a rigid polymer (likely polypropylene or similar polyolefin) storage case with an applied waterproof coating. The polymer base itself is generally stable and does not leach BPA or phthalates under normal conditions. However, the waterproof treatment coating is the material of concern: waterproof coatings on plastic cases often contain fluorinated compounds (PFAS family) to repel water, and Plano has not publicly disclosed the specific chemistry of their coating, making full hazard assessment impossible.
The brand's record and disclosure
Plano Molding is a long-established manufacturer of polymer storage products but has not released transparent ingredient disclosure or third-party testing data for waterproof coatings on consumer cases. The company has no known public PFAS phase-out commitment or independent certifications (such as GREENGUARD or similar) specific to this product line. Absence of disclosure is not proof of hazard, but it prevents informed risk assessment.
How it compares in its category
Hard polymer storage cases without waterproof coatings (uncoated or mechanically sealed alternatives) avoid the coating hazard entirely. Cases from brands with explicit PFAS-free or fluorine-free waterproofing statements offer more transparency. The Guide Series 3600 sits in a middle ground: common construction, but opaque chemistry, making direct comparison difficult without competitor disclosure data.
If you buy it
Store food, drinking water, and sensitive items only if you accept the unknown PFAS exposure risk from the waterproof layer. Avoid prolonged contact between moist food and the interior coating; wipe dry after use. Do not heat the case or store items above 60C (140F), as warming can increase any leaching from the coating. Replace if the waterproof layer begins to peel, crack, or cloud, as degradation may release particles and coatings.
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.”
PFAS in waterproof coating
Waterproof polymer case coatings commonly use fluorinated PFAS compounds; Plano's silence on this specific product prevents confirmation, but the hazard class is standard for this application.
Coating degradation and leaching
Over time and with heat, polymer coatings can flake or leach components; no specific data on the Guide Series 3600, but degradation is a known risk for coated plastic containers.
Polymer leaching (base material)
The polypropylene base itself is chemically stable and does not release BPA or common phthalates under normal storage conditions; no hazard identified for the uncoated polymer.
Migration to stored contents
If the waterproof coating contains PFAS or other migrants, contact with stored food or water over time could transfer trace amounts; risk depends on coating formulation and storage duration.
Off-gassing or volatile organic compounds
Rigid plastic cases do not typically off-gas VOCs like soft plastics or foams; the Guide Series 3600 is not expected to emit volatile compounds under normal indoor conditions.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 35% 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.
