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-contact safety — chemically inert, handles extreme temperature changes, and zero chemical migration into your food.
Tempered soda-lime glass is chemically inert and FDA-approved for food contact. It will not leach chemicals into your food at any storage temperature. Avoid extreme temperature swings like freezer-to-hot-oven to prevent thermal shock cracking.
Food-grade polypropylene lids are FDA-approved and BPA-free by nature — one of the safest and most well-characterized plastics for food contact.
Rubbermaid calls the lid material 'StainShield' but does not disclose the specific plastic type. While it is marketed as BPA-free, the lack of transparency on lid composition is a concern since the lid directly contacts your food.
Confirmed BPA-free for both the borosilicate glass container and polypropylene lid.
Both the glass containers and StainShield lids are confirmed BPA-free by Rubbermaid.
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.
Rubbermaid has not published any PFAS-free testing for the Brilliance Glass lid seal. This is common across most food storage brands in this category.
Rated to 500°F — the highest oven temperature in this category. Handles freezer-to-oven transitions, roasting, and baking with ease.
Oven-safe to 450°F without the lid — suitable for reheating, baking, and light roasting directly from the refrigerator.
Four-sided locking clips with silicone seal create a fully leakproof, airtight closure — safe for soups, sauces, and liquid transport.
The snap-seal lids provide airtight, leak-proof closure that handles soups and sauces reliably. A solid choice for packed lunches and meal prep transport.
Both glass container and lid are fully dishwasher safe.
Glass containers and lids are both dishwasher safe. Place lids on the top rack for best longevity.
Four locking tabs require two hands to open and close — slightly frustrating for quick access but necessary for the leakproof seal.
The lids snap shut with latches on two sides, requiring both hands to fully seal. Slightly less convenient for quick fridge grabs, but the payoff is a reliably airtight closure.
Rectangular containers stack neatly when lidded — efficient for fridge and pantry organization.
Rectangular containers with flat lids stack neatly in the fridge and cabinet, making efficient use of shelf space.
Everything you need to make the call - who each one is for, and who should skip it.

You prefer large 8-cup containers for batch cooking and family meal prep
You want glass containers with leak-proof lids that can go from freezer to oven to dishwasher

The main thing to know
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.
The lid material is Rubbermaid's proprietary 'StainShield' plastic with no disclosed resin type. While it is BPA-free, the lack of material transparency is why this glass container scores lower than you might expect.
Skip this if you...
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
You want full material transparency on every food-contact surface including the lid
You prefer borosilicate glass for better thermal shock resistance when moving between extreme temperatures
You want the most affordable glass storage option and are fine with press-fit lids
Neither of these quite what you're looking for?
