Bentgo Salad Container
Lower concern for typical salad container; no PFAS-prone features, but brand offers no transparency.
Bentgo Salad containers are food-contact plastics without disclosed nonstick, water-resistant, or stain-resistant treatments, the primary PFAS vectors. The brand does not claim PFAS-free status or hold third-party verification. No public lab data exists.

Why this grade
Category baseline
food packaging is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
Bentgo Salad Containers are constructed from polypropylene (PP) or a similar food-grade thermoplastic, materials chosen for rigidity, transparency, and low chemical leaching under normal use. Polypropylene does not require a chemical non-stick coating (unlike cookware), so there is no Teflon-type coating or similar Teflon-family coating present. The container's design for cold salad storage means it is not exposed to high temperatures that would accelerate polymer degradation or monomer migration into food.
The brand's record and disclosure
Bentgo is part of Bento Box Co, a relatively smaller consumer container manufacturer. Public records show no major recalls or safety violations specific to Bentgo salad containers. The brand does not provide explicit third-party certifications (e.g. FDA, BPA-free claims) in widely accessible marketing materials, nor do they offer detailed PFAS stance documentation. This silence on chemical transparency is a compliance gap but not evidence of hazard; many polypropylene container makers share this limited disclosure posture.
How it compares in its category
Salad containers in this segment (Rubbermaid, Sistema, OXO, Bentgo) are functionally similar: plastic, stackable, cold-storage focused. Bentgo's price and durability are mid-range. Competitors with explicit BPA-free labeling or third-party certifications (e.g. Rubbermaid Brilliance) offer stronger transparency, but this does not imply Bentgo containers contain BPA; polypropylene inherently excludes it. Bentgo is neither a premium safe-choice brand nor a budget discount option with known defects.
If you buy it
Use only for cold or room-temperature foods; do not microwave or expose to hot liquids, as polypropylene softens above 100C and may degrade. Hand wash or use the top rack of dishwashers at moderate temperature. Inspect the container every 12-18 months for stress cracks, cloudiness, or warping, signs of polymer fatigue; replace if observed. Store away from direct sunlight and strong chemical odors to minimize off-gassing and degradation.
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 / BPS leaching
Polypropylene does not require BPA or BPS as a base monomer or hardener. No recalls or test reports document these compounds in Bentgo salad containers. Risk is negligible at normal cold storage use.
Phthalate esters (plasticizers)
Polypropylene formulations may include trace phthalate or non-phthalate plasticizers for flexibility; disclosure on Bentgo products is absent. For cold salad storage, leaching is minimal. Heating would increase risk; as-advertised use does not present established hazard.
Microplastic shedding
Repeated washing, stacking, and wear can cause degradation of polypropylene surfaces, releasing microparticles. Salad containers experience moderate mechanical stress. No product-specific data exists, but this is a potential hazard common to all plastic food storage over time.
Coating or ink migration (lids, labels, graphics)
Bentgo containers feature printed graphics on lids and edges. No recalls or testing reports document ink or adhesive leaching. FDA food-contact plastic regulations govern such inks, and compliance is presumed; however, brand does not publish testing certificates.
Polymer degradation under UV or heat stress
Exposure to direct sunlight, hot dishwashers, or storage near heat sources can embrittle polypropylene and release small amounts of oligomers or residual monomers. This risk is low for typical kitchen storage but increases with misuse (e.g. outdoor storage, high-temp dishwashing).
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.
