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.
Borosilicate glass is the gold standard for food-contact safety — chemically inert, handles extreme temperature changes, and zero chemical migration into your food.
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.
Food-grade polypropylene lids are FDA-approved and BPA-free by nature — one of the safest and most well-characterized plastics for food contact.
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 borosilicate glass container and polypropylene lid.
Confirmed BPA-free — polypropylene never contains BPA as an ingredient.
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.
SC Johnson has not published PFAS-free testing for Ziploc containers.
Rated to 500°F — the highest oven temperature in this category. Handles freezer-to-oven transitions, roasting, and baking with ease.
Not oven-safe — polypropylene cannot withstand oven temperatures and will deform above approximately 220°F.
Four-sided locking clips with silicone seal create a fully leakproof, airtight closure — safe for soups, sauces, and liquid 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 container and lid are fully dishwasher safe.
Both container and lid are fully dishwasher safe with no rack restrictions.
Four locking tabs require two hands to open and close — slightly frustrating for quick access but necessary for the leakproof seal.
One-handed press-to-snap operation — the easiest and fastest lid mechanism in this comparison. Ideal for quick fridge access with full hands.
Rectangular containers stack neatly when lidded — efficient for fridge and pantry organization.
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 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
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
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.
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 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 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"
Neither of these quite what you're looking for?
