Glad Food Storage Containers To Go Lunch 32 oz (4 Containers)
Lower-concern option; basic food-storage plastic with no known PFAS risks but no brand transparency.
Glad's To Go lunch containers are polypropylene plastic, a commodity material not typically treated with PFAS coatings. Glad makes no public PFAS claims or disclosures. No third-party testing or certification data is publicly available for this specific product line.

Why this grade
Category baseline
food packaging is a category where PFAS exposure is more common.
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
These containers are polypropylene (PP, #5 plastic), a thermoplastic polymer chosen for food storage because it is chemically stable at room temperature and resistant to many household substances. PP does not contain BPA, phthalates, or other legacy plasticizers that were common in older food plastics. However, polypropylene can degrade and leach if exposed to prolonged heat, high temperatures, or certain solvents, making proper use critical.
The brand's record and disclosure
Glad is owned by Clorox and manufactures a broad range of food-storage and waste products. The brand does not publicly disclose detailed material sourcing, additive lists, or independent safety certifications for these containers. No major recalls or chemical safety scandals specific to Glad food-storage containers are on public record. The brand's silence on PFAS and material transparency is typical of the mass-market food-storage category but leaves consumers without third-party verification.
How it compares in its category
Polypropylene lunch containers are standard and among the safest single-use food-storage plastics available. They compare favorably to PET (#1) and PVC (#3) in terms of chemical stability. Premium alternatives (glass, stainless steel) eliminate plastic leaching risk entirely but add cost and weight; budget plastic alternatives may use less-vetted additives or colorants. Glad's offering sits in the middle-market tier without certification marks (BPA-free labels alone do not verify other additives).
If you buy it
Do not microwave these containers or fill them with hot food; PP softens above 160°F and may leach additives when heated. Use for cold or room-temperature items only. Hand-wash rather than dishwasher (heat and detergent exposure accelerates degradation). Replace containers if you notice cloudiness, cracks, or odors, as these signal polymer breakdown. Avoid prolonged contact with fatty foods, oils, or acidic items if containers are very old, as these can accelerate leaching.
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.”
Heat-induced leaching and polymer breakdown
Polypropylene begins to soften and may release additives or oligomers when exposed to temperatures above 160°F. Microwave heating or storage of hot foods significantly increases this risk.
Additive migration (non-plastic specificity)
Glad does not publicly disclose colorants, UV stabilizers, or processing aids used in these containers. Common additives in budget PP containers (e.g., hindered-amine light stabilizers, antimony compounds as catalysts) can migrate in trace amounts, though no specific reports exist for Glad containers.
Microplastic fragmentation over time
Repeated washing, stacking, and mechanical stress can cause microscopic PP particles to flake into food, especially if containers are used for years. Risk is low for normal use but increases with damage or age.
Degradation from fatty or acidic foods
Oils, vinegars, and citric acids can soften polypropylene and increase leaching of additives or polymer chains. This is a concern primarily for long-term storage (weeks or months) rather than typical lunch-box use.
Contamination from mold or bacterial growth if not dried fully
Food-storage containers with poor drainage or residual moisture can harbor mold or bacteria, especially in lids. This is a hygiene issue rather than a material hazard but is relevant to Glad's design with interlocking lids.
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.
