Ziploc · Disposable Food Containers
Ziploc To Go Containers Variety Pack
Possible PFAS in grease-resistant coating; Ziploc silent on PFAS.
Ziploc To Go Containers likely contain polypropylene with a grease-resistant treatment that may include PFAS. Brand makes no public PFAS disclosures or certifications, leaving composition unclear.

The full breakdown
What it's made of and why it matters
Ziploc To Go Containers are polypropylene (PP), a thermoplastic that is generally resistant to leaching under normal cold storage. The stated grease-resistant coating is the critical variable: manufacturers typically use fluorinated compounds (PFAS-class substances) to achieve water and grease repellency on food contact surfaces. Polypropylene itself does not contain BPA or phthalates, but the durability and composition of the coating over time and with repeated use is not independently verified by public sources.
The brand's record and disclosure
Ziploc (owned by SC Johnson) has not publicly committed to PFAS-free formulations or published ingredient transparency for its grease-resistant coatings. SC Johnson's broader sustainability communications focus on recyclability and waste reduction, not chemical disclosure. No major recalls or regulatory actions against Ziploc food containers for chemical leaching have been documented in public records, but the company's silence on PFAS in food-contact coatings is consistent with industry-wide opacity on this issue.
How it compares in its category
Most reusable plastic food containers in the mass market use similar grease-resistant coatings and polypropylene bases. Alternatives include glass (heavier, fragile, no coating concern), silicone (fewer transparency concerns, higher cost), or uncoated polypropylene (loses grease resistance). Ziploc's main competitor, Rubbermaid, has similar material profiles and equivalent PFAS disclosure gaps. Containers marketed as PFAS-free exist but are less common in mainstream retail variety packs.
If you buy it
Reserve these containers for non-greasy, room-temperature or refrigerated foods; avoid using them for oily dressings, butters, or hot foods, which may stress the coating and increase leaching risk. Do not microwave, freeze, or wash in hot water, as thermal stress can degrade the grease-resistant coating over time. Replace containers after 1-2 years of regular use or if the coating shows visible wear, discoloration, or clouding. Hand-wash in cool water rather than dishwasher to extend coating life.
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.”
PFAS in grease-resistant coating
Grease-resistant food-contact coatings commonly use fluorinated compounds; Ziploc has not disclosed coating composition. Migration risk is highest with fatty foods and elevated temperatures.
Polypropylene polymer stability under stress
Polypropylene itself is chemically inert under normal cold storage. Degradation or leaching is not documented for this product at room temperature or refrigeration.
Coating degradation and microplastic release
Repeated washing, temperature cycling, and mechanical wear can break down the grease-resistant layer; degraded coating particles could theoretically enter food, but direct evidence in Ziploc containers is not publicly documented.
BPA or phthalates
Polypropylene formulations for food contact typically do not include BPA or phthalate plasticizers. No public recalls or warnings for these substances in Ziploc containers exist.
Migration at elevated temperatures
Polypropylene has a melting point around 130-171°C; microwave use or hot dishwashing may accelerate coating degradation and potential migration of coating components into food.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 55% 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.
