For most meal preppers, the best leakproof food storage container is the Rubbermaid Brilliance — a clear Tritan system with latching, gasketed lids rated 100 percent leakproof by manufacturer specs, and owners consistently confirm it survives a bag commute with soup inside. If you prefer glass, Glasslock is the durable oven-safe workhorse, Pyrex Freshlock is the budget locking-lid alternative, and the OXO Good Grips Smart Seal (Glass) earns its premium price with a removable, easy-clean silicone gasket. For dry pantry goods, the OXO Good Grips POP line is the airtight standard. Not sure which fits your routine? Our interactive food storage finder narrows it down in under a minute.
Our picks at a glance
- Rubbermaid Brilliance — best for most people: lightweight, latch-sealed Tritan plastic owners consistently call genuinely leakproof and stain-resistant.
- Glasslock — best oven-safe glass: tempered glass rated to 450°F with four-tab locking lids and a reputation for shrugging off drops.
- Pyrex Freshlock — best budget glass: a trusted glass base with BPA-free locking lids at the friendliest price here.
- OXO Good Grips Smart Seal (Glass) — best premium glass: borosilicate bases plus a removable silicone gasket, so nothing funky hides in the lid.
- OXO Good Grips POP — best for dry goods: push-button airtight canisters for flour, rice, and snacks (not for liquids or the microwave).

Rubbermaid Brilliance
What it is: A clear, BPA-free Tritan plastic system with dual latching lids, a built-in gasket, and vents under the latches for splatter-free microwaving, commonly sold as a 10-piece (5-container) set.
Why it leads: Manufacturer specs rate the latched lids as 100 percent leakproof, and owners consistently report carrying soups and saucy leftovers sideways in a bag without spills. Reviewers also repeatedly note that tomato sauce doesn't stain the Tritan like ordinary plastic. It's dishwasher- and freezer-safe, light enough for a backpack, and stacks cleanly.
Owner-reported caveats: The seal only works when both latches are fully clicked — the most common complaint pattern involves lids that weren't seated. Heavy turmeric or oily chili can leave a faint tint over time.
Who should skip it: Anyone wanting oven reheating or avoiding plastic entirely — choose Glasslock or OXO Smart Seal glass instead.
Glasslock
What it is: Korean-made tempered glass containers with four-tab locking lids and silicone gaskets. The oven-safe line is rated by the manufacturer to 450°F (base only); the popular 18-piece set mixes rectangles, squares, and rounds.
Why we picked it: Glasslock is the pattern-of-record for durability in owner reviews: people consistently describe surviving counter drops, years of dishwasher cycles, and freezer-to-microwave routines without seal failure. The glass resists stains and odors completely, and the tabbed lids seal tightly enough for transporting liquids.
Owner-reported caveats: Lids are stiff out of the box and break in with use. A minority of long-term owners report chipping at the rim, so inspect edges periodically. Heat the glass base only — never the lid.
Who should skip it: Commuters counting ounces (glass is heavy) and anyone with limited hand strength who'd find stiff latches frustrating.
Pyrex Freshlock
What it is: Pyrex's locking-lid line — tempered glass bases with BPA-free lids using four locking tabs and a gasket. It's the leakproof sibling of the snap-only Simply Store line, sold individually (~$10 for a 4-cup round) and in sets (~$30–$40 for a 10-piece).
Why we picked it: It's the cheapest way into a genuinely locking glass seal from a brand stocked at nearly every major retailer. Manufacturer specs cover microwave, freezer, and dishwasher use, and owners consistently report the seal handles packed lunches without weeping.
Owner-reported caveats: Lids are bulkier to store than flat snap lids, and the bases aren't oven-rated like Glasslock or OXO's borosilicate. Double-check the listing — Simply Store lids look similar but don't lock.
