Compare Food Storage Containers
Ziploc Food Storage Meal Prep Containers with SmartSnap Technology (Deep Square, 3-Pack) scores higher on safety - here's why.
The most important dimensions, side by side.
Soda-lime glass is chemically inert and FDA-approved — safe for daily food contact. Pyrex US uses tempered soda-lime (not borosilicate), so avoid sudden freezer-to-hot-oven transitions.
Food-grade polypropylene is FDA-approved for food contact and BPA-free by nature — but it's still plastic, which means some chemical migration is possible under heat or prolonged storage.
BPA-free polypropylene lids are FDA-approved and safe at normal storage temperatures — a reliable plastic choice for food-contact lids.
Same food-grade polypropylene as the container — FDA-approved and BPA-free. The SmartSnap mechanism is built into the plastic lid with no separate gasket.
Confirmed BPA-free for both the glass containers and polypropylene lids.
Confirmed BPA-free — polypropylene never contains BPA as an ingredient.
Pyrex has not published PFAS-free testing for the lid material — common across most brands in this category.
SC Johnson has not published PFAS-free testing for Ziploc containers.
Oven-safe to 425°F in a preheated oven — suitable for reheating and light baking, but avoid broiling or rapid temperature changes.
Not oven-safe — polypropylene cannot withstand oven temperatures and will deform above approximately 220°F.
Snap-on lids push on without locking — adequate for refrigerator storage but will not prevent leaks during transport.
SmartSnap provides a click-close seal with positive engagement — leak-resistant for most daily use, though not as reliable as multi-tab locking clip designs.
Both glass containers and PP lids are dishwasher safe — containers on any rack, lids on the top rack.
Both container and lid are fully dishwasher safe with no rack restrictions.
Simple one-handed snap lids lift on and off effortlessly — the easiest daily use in this comparison.
One-handed press-to-snap operation — the easiest and fastest lid mechanism in this comparison. Ideal for quick fridge access with full hands.
Containers stack flat when lidded — efficient for both fridge organization and cabinet storage.
Square design stacks efficiently in the fridge and pantry. Containers nest inside each other when empty.
Everything you need to make the call - who each one is for, and who should skip it.
Go for it if you...
You primarily store leftovers in the refrigerator and want a safe glass alternative to plastic
You want the simplest possible daily use — one-handed snap lids open and close effortlessly
You need an affordable 12-container glass set for under $28
You trust the Pyrex heritage brand and want easy replacement lid availability
You want the most convenient daily-use container with one-handed snap-close lids
You need the most affordable option — under $6 per container is hard to beat
You pack lunches for kids and need lightweight, shatter-proof containers
Convenience and cost matter more to you than eliminating plastic from food storage
The main thing to know
The snap-on lids are not airtight or leakproof. Pyrex Simply Store is designed for home refrigerator use — if you pack lunches or transport food, these lids will shift and leak.
Every surface that contacts your food is polypropylene plastic — the container, the lid, and the seal mechanism. While PP is FDA-approved and BPA-free, families seeking to reduce plastic food contact should look at glass alternatives.
Skip this if you...
You need leakproof containers for transporting lunches, soups, or liquids
You want borosilicate glass — Pyrex US uses soda-lime glass since 1998, which has thermal shock limitations
You want PFAS-free verification on lid materials
You want to reduce plastic contact with your food — glass options exist at similar per-piece prices
You need oven-safe containers for fridge-to-oven cooking
You want PFAS-free verification or detailed material disclosure beyond "BPA-free"
