What Rubbermaid Lunchblox Entrée Kit, Green is made of, ingredients and materials
The Lunchblox Entrée Kit uses polypropylene (PP, plastic #5), a thermoplastic polymer chosen for food storage because it resists moisture, is dishwasher-safe, and does not readily leach chemicals at normal use temperatures. Silicone seals (typically FDA-compliant food-grade silicone) provide an airtight barrier without relying on Teflon-type coating or problematic adhesives. Polypropylene has no reported leaching of BPA, BPS, or phthalates in normal food-contact use, making it one of the more chemically inert single-use plastics.
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.
Microplastics
Polypropylene can shed microparticles if scratched, cracked, or exposed to prolonged heat and mechanical stress. Risk is minimized by careful handling and replacement of visibly damaged containers; heating above manufacturer limits increases degradation risk.
Source, EPA ↗Silicone seal degradation and microbial growth
Silicone seals can degrade, discolor, or harbor bacteria if not cleaned thoroughly after each use or if stored wet. Inspect seals regularly and replace the container if seals no longer seal airtight or show permanent discoloration.
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 contain BPA, BPS, or phthalates as manufacturing additives; no leaching reported in normal food contact or after washing. No recalls or independent testing alerts on record for this product.
Source, FDA ↗Lead
Polypropylene food containers are not typically colored with lead or cadmium pigments under current FDA food-contact regulations. No specific recalls or safety warnings for Rubbermaid Lunchblox pigmentation on record.
Source, ATSDR ↗Off-gassing or volatile organic compounds (VOCs)
Polypropylene has minimal VOC off-gassing compared to other plastics; any slight odor from new containers typically dissipates within days of use and does not indicate a safety concern.
The full breakdown
The brand's record and disclosure
Rubbermaid (Newell Brands) does not publicly disclose detailed PFAS statements for individual products, but the company has faced no significant recalls or regulatory actions related to chemical leaching from Lunchblox containers. The product line has been in market for over a decade without documented safety incidents tied to material degradation or contaminant migration. Rubbermaid maintains FDA compliance for food-contact plastics but does not prominently advertise chemical testing results on consumer-facing materials.
How it compares in its category
Polypropylene food containers like Lunchblox occupy a middle tier of chemical safety in the lunch-kit market, safer than older polycarbonate (which contains BPA) and PVC, but less extensively third-party tested than some specialty brands (e.g., Pyrex glass or stainless steel alternatives). Silicone seals are standard across mid-range reusable containers and carry lower leaching risk than traditional rubber gaskets. The Lunchblox line's multi-compartment design and durability position it as a common school and office choice with no specific safety red flags versus comparable polypropylene competitors.
If you buy it
Avoid heating polypropylene above 100 degrees Celsius (212 Fahrenheit); hand-wash or use the top rack of the dishwasher to extend seal life and reduce thermal stress to the plastic. Replace containers if seals become loose, brittle, or discolored, as degraded silicone seals can fail to prevent leakage and microbial growth. Do not use with hot liquids or fatty foods at high temperature; room-temperature or gently warmed foods are safest. Inspect for cracks or stress marks periodically; intact plastic is the baseline for food safety.
