Tupperware Freezer Mates Plus Food Storage Container
Lower PFAS concern; rigid plastic storage containers rarely use fluorinated coatings, but verify via Tupperware directly if reassurance needed.
Tupperware Freezer Mates Plus are rigid polypropylene food storage containers with no known Teflon-family coating or Teflon-type coating coatings. The brand makes no PFAS claims or disclosures.

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
Tupperware Freezer Mates Plus containers are rigid polypropylene (PP, #5 plastic), a thermoplastic polymer chosen for freezer durability and chemical resistance. PP does not require Teflon-type coating or fluorinated coatings for non-stick function and does not contain BPA or phthalate plasticizers in modern formulations. The material is inherently stable below its melting point (around 160°C) and does not leach monomers or degradation products during normal refrigerator and freezer storage.
The brand's record and disclosure
Tupperware has not published detailed chemical composition disclosures or third-party material certifications for individual SKUs, though the company does market products as BPA-free. The brand has faced no major recalls or safety warnings specific to Freezer Mates Plus containers. Tupperware's parent company underwent bankruptcy restructuring in 2024, but no chemical safety lapses have been publicly documented for this product line.
How it compares in its category
Rigid PP containers like this occupy a middle safety tier: they avoid BPA and phthalates better than older polycarbonate or flexible PVC alternatives, but offer less transparency than glass or stainless steel. Freezer-specific containers are lower risk than microwave-safe products because freezer temperatures do not accelerate leaching. This product is functionally equivalent to store brands and Rubbermaid PP freezer containers in terms of chemical safety profile.
If you buy it
Keep containers away from direct heat sources and do not microwave (polypropylene softens around 120°C). Replace lids if they become cloudy, warped, or cracked, as degraded plastic can shed microparticles. Wash by hand or in the cool cycle of a dishwasher; avoid abrasive scrubbing that can scratch surfaces and create nucleation sites for degradation. Store away from strong solvents and oils, which can slowly diffuse into PP and weaken its structure over years.
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.”
Microplastic shedding from mechanical wear
Freezer-use containers experience less thermal cycling than everyday products, reducing microplastic risk. Visible wear to the lid snap or container walls warrants replacement to minimize ingestion of wear particles.
BPA or BPS leaching
Tupperware's modern PP formulations are documented as BPA-free; no evidence of BPS substitutes in this product line has emerged in public records.
Aluminum leaching
This is a polypropylene container with no aluminum components; hazard does not apply to this product.
Phthalate plasticizers
Modern polypropylene rigid containers do not require phthalates for flexibility. No regulatory or independent testing has flagged phthalates in Tupperware PP food storage products.
Odor transfer and staining from residual food films
Users commonly report that PP containers absorb odors and turmeric stains over time, a cosmetic rather than health issue. This is a property of polypropylene, not a manufacturing defect specific to Tupperware.
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.
