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 freezer-to-oven transitions without shattering, and zero chemical migration.
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.
OXO does not disclose the specific plastic type used in the lid. While it includes a silicone gasket and is BPA-free, the lack of material transparency is a concern since the lid contacts your food directly.
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 plastic lid components.
Confirmed BPA-free — polypropylene never contains BPA as an ingredient.
OXO has not published PFAS-free testing for the silicone gasket or lid — common across most brands in this category.
SC Johnson has not published PFAS-free testing for Ziploc containers.
Borosilicate glass goes from freezer to preheated oven without needing to thaw first — full versatility for reheating, baking, and roasting.
Not oven-safe — polypropylene cannot withstand oven temperatures and will deform above approximately 220°F.
Four locking tabs with a silicone gasket create a fully leakproof, airtight seal — safe for soups, sauces, and anything you need to 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 refrigerator access but the trade-off for a 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.
Stacks neatly in the fridge or freezer and nests in the cabinet when stored without lids.
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.

Convenience and cost matter more to you than eliminating plastic from food storage
The main thing to know
OXO does not disclose the specific plastic type used in the lid. While it is BPA-free with a silicone gasket, buyers who want full material transparency should consider alternatives like Glasslock that disclose PP lids.
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 prefer one-handed convenience — the 4-tab locking mechanism requires two hands
You need a budget-friendly set — at $14.99 per single container, a full set adds up quickly
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
