Rubbermaid Pack + Go Sandwich & Salad Container
Lower PFAS concern, but Rubbermaid remains silent on PFAS practices.
Polypropylene food containers are not inherently fluorinated. No public evidence Rubbermaid adds PFAS treatments to this product, but the brand discloses nothing about PFAS or chemical policy.

Why this grade
Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
Category baseline
food packaging is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
The full breakdown
What it's made of and why it matters
This container is polypropylene (PP), a thermoplastic polymer commonly used in food storage because it resists cracking and maintains structural integrity across temperature ranges. PP does not contain BPA by chemical nature and is generally considered one of the more stable plastics for food contact. The sandwich and salad design includes snap-lock lids, typically made from the same PP resin, which reduces complexity and cross-material leaching risks.
The brand's record and disclosure
Rubbermaid is a major food-storage manufacturer owned by Newell Brands and has no public recalls or documented safety violations for this product line. The company does not publish detailed PFAS sourcing or testing data (the 'silent' stance noted), which limits transparency but does not indicate a known problem. Rubbermaid products generally meet FDA food-contact regulations and carry standard polypropylene certifications, though the brand could be more proactive in disclosing polymer composition and processing details.
How it compares in its category
Polypropylene containers occupy the middle-to-lower-risk segment of food storage: safer than older polycarbonate (BPA risk) and PVC (phthalate risk), but less inert than borosilicate glass. This Rubbermaid model is typical of mass-market PP lunch containers and performs similarly to competitors like Sistema and OXO. Brand reputation and snap-lock durability give it a slight edge in category consistency, though no material advantage over other PP options.
If you buy it
Avoid prolonged microwave heating or direct dishwasher exposure to degraded seals; use on low-heat settings only or transfer contents to glass before heating. Replace the lid if visible cracks or clouding develop, as these indicate polymer breakdown and possible microplastic shedding into food. Hand wash with mild soap and cool water to extend life. Do not use for hot foods (above 40C/104F) or oily/acidic liquids stored long-term, which accelerate leaching.
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
Polypropylene does not contain BPA or BPS by composition. No documented contamination in Rubbermaid Pack + Go line.
Phthalates
PP-based containers do not require phthalate plasticizers. Rubbermaid has no reported phthalate issues in this product category.
Microplastics from heating or degradation
Repeated microwave use or mechanical wear (cracks, cloudiness) can cause PP to shed microparticles into food. Risk is low under normal use but increases with age and thermal cycling.
Additive leaching (non-BPA)
Polypropylene may contain processing aids or colorants that can migrate at elevated temperatures or into fatty/acidic foods. Risk is minor under standard cold-to-warm food storage but not zero.
Lid seal degradation
Snap-lock PP lids are known to lose elasticity and hermetic seal over time with repeated washing, allowing air contact and potential food spoilage or odor absorption rather than chemical toxicity.
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.
