Low PFAS risk; polypropylene lunch box unlikely source.
Sistema's plastic food containers are typically polypropylene, a commodity plastic with lower inherent PFAS risk. No PFAS treatment common in standard food storage; brand makes no claims either way.

What Sistema Lunch Stack Rectangle To Go is made of, ingredients and materials
This is a polypropylene (PP) food storage container, a thermoplastic polymer chosen for food contact because it does not contain BPA or common phthalates by design. Polypropylene is considered a lower-concern plastic for food storage compared to polycarbonate or vinyl. The main material risk with PP is leaching of unreacted monomers or additives under high heat or prolonged contact with fatty or acidic foods, though this remains uncommon under normal lunch-box use (room temperature, short storage windows).
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
Prolonged heating, scratching, or UV exposure can cause polypropylene to shed microparticles. Normal lunch-box use (room temperature, hand-washing) presents low risk; avoid microwave and direct sunlight for long-term storage.
Source, EPA ↗Mold and bacterial growth in seals
Multi-piece stacking containers with hinges and snap closures can trap moisture and food residue in crevices. Regular disassembly, thorough drying, and prompt washing reduce this risk; it is not unique to Sistema.
Leaching of unreacted monomers or additives under heat or prolonged fatty-food contact
All PP containers carry a theoretical low risk of monomer or additive migration if exposed to high heat or stored with oily foods for extended periods. Room-temperature, short-term lunch storage minimizes this concern.
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 require BPA as a building block. No recalls or testing concerns on record for Sistema PP containers in this regard.
Source, FDA ↗Phthalates
Polypropylene is inherently rigid and does not typically require phthalate plasticizers. No public reports of phthalate contamination in Sistema lunch containers.

The brand's record and disclosure
Sistema is a New Zealand-based food-storage brand with a long retail presence and no established recalls or safety controversies in public record related to plastic leeching or chemical contamination. The brand does not publicly disclose detailed ingredient or additive lists, and takes no visible stance on PFAS avoidance. No third-party testing or certifications (e.g., BPA-free labeling) are noted for this specific product line on available packaging or retailer sites.
How it compares in its category
Polypropylene lunch containers are a middle-ground option, safer than polycarbonate in terms of BPA risk, but less transparent on additives than glass or stainless-steel alternatives. Sistema containers are broadly comparable to other mass-market PP lunch boxes (e.g., Rubbermaid, Lock & Lock) in material and price tier. The Cocomelon branding and rolling puppy toy indicate this is a licensed, child-focused product; no additional safety claims or certifications specific to children appear to differentiate it.
If you buy it
Do not microwave or expose to high heat; store at room temperature and hand-wash with mild soap. Avoid prolonged contact with oily, acidic, or hot foods; use for room-temperature or mildly warm items (below 60 C / 140 F). Inspect regularly for cracks, discoloration, or warping; replace if the container becomes brittle or develops odors. Ensure all seals and hinges function properly to prevent mold growth from moisture if used daily.
