Sistema Nest IT Meal Prep Food Storage Containers
Lower PFAS concern for basic food storage; no coating or treatment claims suggest minimal risk.
Sistema Nest IT containers are primarily polypropylene plastic with no disclosed nonstick, water-resistant, or stain-resistant treatments, typical for affordable meal-prep boxes. PP is not inherently linked to intentional PFAS use, though the brand offers no PFAS disclosure.

No PFAS disclosure
No public statement about PFAS in this product.
Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
Sistema Nest IT containers are polypropylene (PP), a thermoplastic polymer rated for food contact and considered one of the safer plastics for storage. Polypropylene has a melting point around 130°C (266°F) and does not contain BPA or phthalates in its base formulation. The material is chemically stable at room temperature and during cold/refrigerated storage, which is the primary use case for meal prep containers. Lids typically include gasket seals, usually silicone or rubber, which do not introduce known contaminants if they remain intact.
The brand's record and disclosure
Sistema is a New Zealand-based manufacturer that has not made public statements about PFAS use or avoidance in this product line, nor has it published third-party safety certifications specific to chemical migration testing. The brand is known for practical, durable food storage design and does not have widely documented recalls or safety controversies related to chemical leaching. No formal evidence of antimicrobial coatings or stain-resistance treatments has been identified on the Nest IT line, reducing likelihood of intentional additive hazards. The brand's silence on disclosure does not indicate a safety failure, but reflects a market segment where transparency is not yet standard.
How it compares in its category
Polypropylene food storage containers are mid-range in safety compared to glass (inert but fragile) and stainless steel (inert, durable, but more expensive). They outperform older polycarbonate or polyethylene terephthalate (PET) alternatives in terms of chemical stability. The Nest IT design includes snap-lock lids rather than soft silicone seals on the entire perimeter, which reduces surface area for seal degradation and potential leachate pathways. Among mass-market plastic meal prep lines, this product sits in the standard PP category with no reported added risk factors.
If you buy it
Do not use these containers for hot foods or in the microwave above 80°C (176°F); polypropylene can warp and leach chemicals when exposed to sustained heat. Hand wash or use the top rack of a dishwasher (many PP containers yellow or degrade in high-heat cycles; check manufacturer guidance). Inspect seals and lids quarterly for cracks, cloudiness, or permanent discoloration; replace if gaskets harden or separate. Store away from direct sunlight and strong solvents (bleach, vinegar in high concentration) to extend polymer life and prevent brittleness.
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 / Bisphenol A and phthalates
Polypropylene does not contain BPA or ortho-phthalates in its base formulation. No evidence of these chemicals in Sistema Nest IT containers has been reported or identified in public recalls.
Microplastics from degradation when heated
Repeated heating above polypropylene's safe temperature (80°C) or microwave use can cause crazing, warping, and particle shedding. Risk is avoidable through adherence to temperature limits and hand washing where possible.
Mold and bacterial growth in seals
Snap-lock gaskets and recessed lid channels can trap moisture and food residue if not thoroughly cleaned. Regular disassembly and drying of seals reduces this risk significantly.
Leaching from lid coatings or colorants
No antimicrobial or non-stick coatings are documented on this product line. Pigments used in colored containers are not documented as problematic for this brand, though full color-additive transparency is lacking.
Off-gassing or odor from new plastic
New polypropylene containers may emit a mild plastic smell on first use. This typically dissipates within hours to days and is not indicative of chemical migration; airing containers before first food use is a reasonable precaution.
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.
