Tupperware Bento Style Lunch Box & Water Bottle
Lower concern; standard plastics unlikely to contain PFAS, but no brand transparency.
Tupperware lunch boxes use conventional plastics without known PFAS coatings. Brand provides no PFAS disclosure, limiting full assurance.

What Tupperware Bento Style Lunch Box & Water is made of, ingredients and materials
The lunch box is polypropylene (PP) plastic, a commodity thermoplastic with a melting point around 130°C. The water bottle is stainless steel (typically 18/8 or 18/10 grade), an inert metal alloy. Polypropylene is widely used for food storage because it does not leach BPA or phthalates under normal conditions. Stainless steel does not leach metals into cold or room-temperature liquid under normal use.
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.
Coating degradation and leaching from plastic container
Polypropylene degrades when exposed to high heat or prolonged UV light. Microwave use or hot-fill conditions may accelerate softening and potential migration of oligomers; degraded plastic should be replaced.
Microplastic generation from wear
Repeated washing, abrasion, or degradation of the polypropylene container may generate microscopic plastic particles, particularly if the surface is scratched or the plastic becomes brittle with age.
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 or BPS as manufactured. No recall or contamination report exists for this product line.
Source, FDA ↗Phthalate plasticizers
Polypropylene is a rigid plastic that does not require phthalate plasticizers. No data suggests phthalate contamination in Tupperware polypropylene products.
Heavy metals
Food-grade stainless steel (18/8 or 18/10) is chemically stable and does not leach iron, chromium, or nickel into cold beverages under normal conditions. No recalls or contamination reports for this product.

The brand's record and disclosure
Tupperware has not published detailed PFAS or chemical transparency reports, and its stance on hazardous substance disclosure remains opaque. The company has faced no major recalls specific to BPA, phthalates, or heavy metals in this product line on public record. As a mature consumer brand, Tupperware typically adheres to FDA food-contact regulations, but voluntary disclosure beyond compliance is limited.
How it compares in its category
Polypropylene lunch boxes are a standard, lower-concern alternative to older polycarbonate (BPA-containing) designs. Stainless steel bottles are considered the most inert option for beverage storage and avoid concerns tied to plastic liners in metal bottles. This combination positions the set in the middle-to-lower risk tier for food-storage products; it avoids higher-concern materials like melamine or unlined aluminum.
If you buy it
Do not microwave the polypropylene box with food inside; polypropylene softens above 100°C and may leach compounds when heated. Hand-wash or use dishwasher on low heat. Replace the lunch box if the plastic shows cracks, cloudiness, or warping, as degradation can increase leaching risk. The stainless steel bottle requires no special care but should be dried thoroughly after washing to prevent corrosion at seams.
