Quantum QB600 Clear Compartment Storage Box
Lower concern storage product. No PFAS-typical use case identified.
Quantum QB600 is a clear polypropylene storage box with no known PFAS-related coatings or treatments. Manufacturer provides no PFAS disclosure; basic plastic storage carries minimal inherent risk.

No PFAS disclosure
No public statement about PFAS in this product.
The full breakdown
What it's made of and why it matters
The Quantum QB600 is polypropylene (PP), a thermoplastic polymer chosen for food and general storage because it resists moisture, has low density, and is recyclable. PP has a melting point around 130-171°C, making it unsuitable for hot foods or boiling-water dishwashing, but stable at room temperature and mild heat. Unlike polycarbonate or certain older plastics, PP does not contain BPA by design and is considered one of the safer commodity plastics for storage use.
The brand's record and disclosure
Quantum Storage Systems is a manufacturer of industrial and commercial storage products with minimal public transparency on material sourcing or chemical testing disclosure. No major recalls or chemical safety controversies are on record for this product line. The brand does not publish third-party certifications (e.g., FDA, NSF) for the QB600, and PFAS stance is undisclosed, though the lower-concern PFAS assessment reflects the lack of typical fluorochemical use in rigid storage containers.
How it compares in its category
Polypropylene storage boxes are standard in this category and are generally safer than older PVC or acrylic alternatives for food contact. Many competitors (Rubbermaid, Cambro, etc.) offer similar PP containers with comparable hazard profiles. The QB600's lack of published testing or certification is typical for basic industrial storage; more rigorous food-grade alternatives exist but carry higher cost and may offer minimal additional safety for dry goods storage.
If you buy it
Keep contents dry and store at room temperature or cool conditions; avoid prolonged exposure to direct sunlight, which can degrade polypropylene over decades. Do not use for hot liquids or foods above 60°C (140°F), and hand-wash rather than machine-wash to extend lid and hinge life. Inspect periodically for stress cracks, discoloration, or odor changes; replace if the container becomes brittle or cloudy, as this signals polymer degradation. Use for non-food dry storage (hardware, craft supplies, etc.) without additional concern.
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.”
BPA and BPS leaching
Polypropylene does not contain bisphenol A or BPS by formulation, and no recalls or contamination reports exist for this product. This is a recognized safety advantage of PP over polycarbonate and older plastics.
Microplastic shedding from degradation
Polypropylene can fragment under prolonged UV exposure or mechanical stress. For a storage box kept indoors, this risk is low, but if stored outdoors or in hot direct sunlight for years, microplastic particles may shed into contents; not established as a concern for the QB600 specifically.
Off-gassing and odor (volatile organic compounds)
New polypropylene containers may emit a mild plastic odor when first opened, typically polypropylene-specific rather than hazardous; odor dissipates within days to weeks with ventilation. No documented VOC or formaldehyde release is typical for PP, distinguishing it from some other plastics.
Phthalate plasticizers
Polypropylene is a rigid plastic that does not require phthalate plasticizers for flexibility. No evidence of phthalate contamination exists for this product category; phthalate hazard is relevant to soft vinyl or PVC, not PP.
Coating or ink toxicity (labeling/printing)
No information is publicly available on inks or labels used on the QB600. Standard commercial storage containers use FDA-compliant inks, but Quantum Storage provides no visible certification; risk is low for dry goods but unverified.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% 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.
