Bentgo Kids Stow & Go Lunch Box
Lower concern. Bentgo does not disclose PFAS; polypropylene itself typically lower risk.
Bentgo Kids lunch boxes are primarily polypropylene and stainless steel with no known PFAS-containing coatings. Brand is silent on PFAS; no third-party testing found, but core materials carry lower inherent concern.

What Bentgo Kids Stow & Go Lunch Box is made of, ingredients and materials
This lunch box is constructed primarily from polypropylene (PP), a thermoplastic polymer assigned resin code 5. Polypropylene is a food-contact approved plastic in the United States and Europe, resistant to warping at moderate temperatures, and does not contain BPA or BPS by its base formulation. The stainless steel hinges and latches are inert and do not leach into food. No ceramic, enamel, or non-stick coatings are mentioned in available product descriptions, eliminating those specific risks.
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 during heating
While polypropylene is microwave-safe at low-to-moderate temperatures, repeated high-heat exposure or damage can accelerate plastic degradation. Avoiding microwave heating of the assembled lunch box mitigates this concern.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
BPA & bisphenols
Polypropylene does not inherently contain BPA or BPS. No recalls or test reports of BPA/BPS presence in Bentgo Kids products have been documented.
Source, FDA ↗Phthalate plasticizers
Polypropylene is a rigid plastic that typically does not require phthalate plasticizers. No evidence of phthalate use in this product line exists in public records.
Stainless steel corrosion or nickel leaching
Stainless steel hinges and latches on food-contact products are standard and do not leach measurable nickel or iron into dry food or typical beverages stored in the compartments.
Colorant or additive toxicity
No specific dye, pigment, or additive composition has been disclosed by Bentgo or flagged in safety reviews. Polypropylene colorants in food-contact applications are typically regulated under FDA compliance frameworks.
The full breakdown
The brand's record and disclosure
Bentgo has not published detailed material safety data sheets or third-party certifications (such as BPA-free testing reports) in widely accessible form, though the brand markets the product as BPA-free on packaging. No recalls or contamination incidents involving this lunch box model have been reported to the Consumer Product Safety Commission or media outlets. The company's silence on PFAS reflects a common industry position rather than a red flag unique to Bentgo.
How it compares in its category
Polypropylene lunch boxes are among the most common food-storage containers sold and represent a middle ground, more durable than single-use plastics but less inert than glass or stainless steel. Compared to compartmentalized lunch boxes made from lower-grade plastics or those with non-stick (Teflon-type coating) coatings, polypropylene is a lower-concern base material. The sealed latch design (relying on mechanical closure, not adhesives or special coatings) is consistent with standard food-container engineering.
If you buy it
Avoid microwave heating of the filled lunch box; remove food and transfer to microwave-safe dishes. Hand-wash in warm soapy water; polypropylene can degrade slightly under hot dishwasher cycles and prolonged high heat. Replace the box if the plastic becomes visibly cracked, cloudy, or develops persistent odors, as these signal advancing material degradation. Store away from direct sunlight when empty to slow oxidative breakdown of the polymer over years of use.
