Rubbermaid Pack & Go 4.57cups/ 1.16quart Ribbon Bento Box with Mini Bite, Meal Prep Container with Compartments and Divi
Lower concern. Rigid PP food containers typically lack PFAS coatings.
Rubbermaid Pack & Go is a rigid polypropylene bento box with compartments. No PFAS disclosure found, but bare PP containers are not a known PFAS risk category.

What Rubbermaid Pack & Go 4.57cups/ 1.16quart is made of, ingredients and materials
This container is rigid polypropylene (PP), a thermoplastic rated for food contact by FDA. PP is one of the more chemically stable plastics at room temperature and does not contain the endocrine disruptors found in some alternatives like polycarbonate. The compartmented design keeps foods separated, which is convenient but also means more plastic-air interface where volatile compounds could theoretically migrate if misused.
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
Repeated mechanical stress (dropping, impact), UV exposure, and microwave heating accelerate PP embrittlement and surface shedding. Visible cloudiness or stress cracks signal potential particle release into food.
Source, EPA ↗Heat-induced degradation and volatiles
PP has a melting point around 165°C but degrades faster and may release volatile compounds if heated above 140°C, such as in dishwashers or microwaves. Hand washing and room-temperature storage minimize this risk.
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 bisphenol A or its substitutes; these are common in polycarbonate and some epoxy linings, not PP. No recalls or reports for this product.
Source, FDA ↗Phthalates
Rigid PP does not require phthalate plasticizers. Phthalate concern is high in soft flexible plastics (PVC, low-density PE) and is not established for Rubbermaid PP containers.
Source, ATSDR ↗Additive leaching (colorants, UV stabilizers)
PP food containers are regulated by FDA; manufacturers must use approved colorants and additives. No published testing or recalls for Rubbermaid bento boxes show leaching of pigments or stabilizers into food under normal storage and use.
The full breakdown
The brand's record and disclosure
Rubbermaid (Newell Brands) does not publicly disclose material sourcing or third-party testing results for this product line. The brand has not faced documented recalls or regulatory actions related to food container leaching. Rubbermaid has not committed to PFAS-free manufacturing in public statements, though rigid PP containers rarely require PFAS treatments.
How it compares in its category
Polypropylene bento boxes are middle-ground in food-storage safety. They sit between glass (more inert but fragile) and soft-sided silicone or thin plastics (higher leaching potential when flexed or heated). Rubbermaid's PP construction is typical for this price and durability tier; no material advantage or disadvantage versus peer brands using the same resin.
If you buy it
Do not microwave or dishwash at high temperature; PP softens above 140°C and can degrade or leach. Hand wash with mild soap and inspect regularly for stress cracks, cloudiness, or warping, which indicate material breakdown. Replace if cracks appear. Store away from direct sunlight to slow UV degradation. Use only for foods, not chemicals or cleaning products.
