Compare Food Storage Containers
Which scores higher on safety? R3 breaks it down.
The most important dimensions, side by side.
Borosilicate glass is the gold standard for food storage — chemically inert, thermal shock-resistant, and FDA-approved. It will not leach chemicals into your food at any temperature, and it can handle sudden temperature changes that would crack regular glass.
Borosilicate glass is the gold standard for food-contact safety — chemically inert, handles extreme temperature changes, and zero chemical migration into your food.
Amazon Basics does not disclose the specific plastic type used for the lids. While the lids are marketed as BPA-free, the lack of material transparency is a concern since the lid contacts your food directly. The blue silicone gasket ring is a good sign, but the lid body plastic remains unknown.
Food-grade polypropylene lids are FDA-approved and BPA-free by nature — one of the safest and most well-characterized plastics for food contact.
Both borosilicate glass containers and plastic lids are confirmed BPA-free by Amazon Basics.
Confirmed BPA-free for both the borosilicate glass container and polypropylene lid.
Amazon Basics has not published PFAS-free testing for the lid seal. This is typical across most food storage brands in this category.
No PFAS-free testing has been published for the lid seal — common across the entire category. The silicone gasket is not a PFAS risk by material nature.
Oven-safe to 450°F without the lid. Borosilicate glass handles sudden temperature changes better than soda-lime glass, so moving from freezer to oven is less risky.
Rated to 500°F — the highest oven temperature in this category. Handles freezer-to-oven transitions, roasting, and baking with ease.
Four-sided locking clips with a silicone gasket ring provide the best leak protection in this category. You can transport soups, sauces, and liquids with confidence.
Four-sided locking clips with silicone seal create a fully leakproof, airtight closure — safe for soups, sauces, and liquid transport.
Glass containers are fully dishwasher safe. Lids can go in the dishwasher but hand washing is recommended for longevity of the silicone gasket.
Both glass container and lid are fully dishwasher safe.
Each lid has four locking tabs that must be clipped open and shut individually. This requires two hands and takes longer than snap-on lids — the trade-off for that excellent leak protection.
Four locking tabs require two hands to open and close — slightly frustrating for quick access but necessary for the leakproof seal.
Both rectangular and round containers stack neatly with their flat lids, making good use of fridge and cabinet shelf space.
Rectangular containers stack neatly when lidded — efficient for fridge and pantry organization.
Everything you need to make the call - who each one is for, and who should skip it.
Go for it if you...
You want the best glass material available for food storage at a budget-friendly price under $25
You transport food regularly and need the most leak-resistant locking clip seal system
You want borosilicate glass that handles freezer-to-oven temperature changes without cracking
You are comfortable with the BPA-free claim on the lid even though the specific plastic type is not disclosed
You want the safest material combination available — borosilicate glass with disclosed food-grade PP lids
You need leakproof containers for transporting soups, sauces, or meal prep
You want the highest oven temperature rating in this category at 500°F
You prefer large 8-cup containers for batch cooking and family meal prep
The main thing to know
The lid plastic type is not disclosed. Despite having the best container glass material (borosilicate), the unknown lid composition holds this product back from a top safety score. If Amazon Basics disclosed the lid plastic as PP, the overall score would jump significantly.
At $15 per container, this is 5x more expensive per piece than the Pyrex Simply Store 12-pack. The premium is justified for families who prioritize material safety and transport, but budget-conscious buyers can get safe glass storage for much less.
Skip this if you...
You need full material transparency on all food-contact surfaces including the lid plastic
You want quick one-handed access to containers and find four-tab locking lids frustrating for daily use
You prefer silicone or PP lids with explicitly disclosed material composition
You are on a budget — at $15/piece, a full set of containers adds up quickly
You prefer one-handed convenience — the 4-tab locking mechanism requires two hands
You want a variety of container sizes — this set only includes 8-cup containers
