Bentgo Easylunchboxes 4-Compartment Oval Bento Lunch Box
Lower concern. Rigid plastic bento box without nonstick or water-repellent coatings.
Bentgo bento boxes are made from polypropylene plastic, which does not require PFAS coatings. No nonstick, stain-resistant, or water-repellent treatments typical of PFAS products are marketed.

What Bentgo Easylunchboxes 4-Compartment Oval is made of, ingredients and materials
The Bentgo EasyLunchboxes are injection-molded polypropylene (PP, #5 plastic) with silicone gasket seals. Polypropylene is a commodity plastic chosen for food contact because it resists degradation from moderate heat and acidic foods better than some alternatives. The absence of a nonstick or water-repellent coating (unlike cookware) eliminates the main vector for PFAS intentional addition. Silicone seals provide the airtight function and are inert at normal use temperatures.
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.
Microplastic shedding with wear
Repeated heating, freezing, and abrasive cleaning can degrade polypropylene surfaces and gaskets, potentially releasing fine plastic particles into food. This is a material-class concern rather than a product-specific defect, but risk increases with age and use intensity.
Additive leaching (colorants, stabilizers, UV absorbers)
Colored polypropylene (if this box is tinted) may contain mineral pigments or organic colorants; opaque white polypropylene often includes titanium dioxide or other stabilizers. Migration at room temperature is typically low, but no independent testing of this product exists in public records.
Silicone seal degradation
Silicone gaskets can absorb oils, odors, and stains over time and may harden or crack from UV exposure or thermal cycling. Degraded seals compromise both airtightness and may shed silicone particles if severely compromised, though this is not common with properly maintained seals.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
BPA & bisphenols
No publicly available information indicates BPA or BPS use in this polypropylene formulation. Many reusable lunch containers market BPA-free status, but EasyLunchboxes does not explicitly state this; absence of disclosure does not confirm absence of concern, only lack of transparent communication.
Source, FDA ↗Phthalates
Polypropylene typically does not require phthalate plasticizers; however, no independent test results for this specific product are on record. Risk is lower than with PVC or flexible PET, but brand does not publish material specifications.

The brand's record and disclosure
EasyLunchboxes (Bentgo parent company) does not publicly disclose detailed material sourcing, third-party certifications, or chemical testing results for this product. No significant product recalls or chemical safety controversies have been established in public records for this bento box line. The brand markets the product as durable and leak-proof but does not emphasize food-safety certifications such as BPA-free labeling or independent testing documentation, which is typical for mid-market reusable lunch containers.
How it compares in its category
Rigid polypropylene bento boxes are the industry standard for reusable lunch containers and are generally considered lower concern for migration than flexible plastic films or thin-walled containers. Many competitors (Rubbermaid, Sistema, Pyrex glass alternatives) use the same or similar materials. Polypropylene's melting point (~130°C / 266°F) makes it durable for cold and room-temperature foods but unsuitable for direct microwave or hot-liquid use, a common trade-off in this category. This product sits in the mainstream tier for material choice and lacks premium certifications that some higher-end brands offer.
If you buy it
Do not use in microwave, especially with hot foods or oil, as polypropylene can soften and may leach additives if warmed repeatedly. Hand wash or use gentle machine cycles; avoid abrasive scrubbers that degrade the surface and may increase microplastic shedding. Inspect seals every 6-12 months for cracks or discoloration; replace the box if gaskets harden or crack. Avoid prolonged contact with alcohol or strong solvents. Store in a cool, dry place away from direct sunlight, which can degrade polypropylene over years.
