Compare Food Storage Containers
Snapware Total Solution 6-Cup Rectangle Glass Food Storage Container scores higher on safety - here's why.
The most important dimensions, side by side.
Tempered soda-lime glass is chemically inert and FDA-approved — no chemicals leach into your food. Slightly more susceptible to thermal shock than borosilicate but perfectly safe for daily use.
Pyrex-branded soda-lime glass is chemically inert and FDA-approved — the same proven glass used in Pyrex Simply Store containers.
Food-grade polypropylene lids are FDA-approved and BPA-free by nature — a solid choice, though not as inert as silicone or glass lid materials.
Snapware does not disclose the specific plastic type in the lid. While the lid is BPA-free with a silicone gasket, the lack of material transparency is a concern for a direct food-contact surface.
Confirmed BPA-free across both the glass containers and polypropylene lids.
Confirmed BPA-free for both the glass container and plastic lid components.
Glasslock has not published PFAS-free testing for the lid silicone gaskets — a transparency gap but not unusual in 2026.
Snapware has not published PFAS-free testing for the lid seal — common across most brands in this category.
Oven-safe to 450°F via TEMPERMAX tempering technology — full versatility from fridge to oven.
Oven-safe to 425°F — handles reheating, baking, and roasting with the lid removed. Avoid sudden temperature changes.
The 4-tab locking clip system with integrated silicone gasket is the most leak-resistant design tested by expert reviewers — ideal for transporting soups and liquids.
Four-latch locking system with silicone seal creates a fully leakproof, airtight closure — safe for soups and liquids during transport.
Both glass containers and polypropylene lids are fully dishwasher safe — no hand-wash components.
Both glass container and lid are fully dishwasher safe.
The 4-tab locking design is very secure but requires snapping all four sides with two hands — slower than press-fit or one-handed snap designs.
Four locking tabs require two hands to open and close — slightly frustrating for quick refrigerator access but necessary for the leakproof seal.
Containers stack with lids on and nest with lids off — though the mixed shapes (round, square, rectangle) are less space-efficient than uniform sets.
Rectangular containers stack neatly in the fridge and cabinet.
Everything you need to make the call - who each one is for, and who should skip it.
Go for it if you...
You want glass containers with genuinely leakproof lids for transporting lunches and soups
You need an affordable 9-container glass set under $40 for meal prep
You regularly move containers from fridge to oven — these handle 450°F
You prefer everything to go in the dishwasher without exception
You need a large 6-cup leakproof container for meal prep and transport
You value the Snapware lifetime warranty against thermal shock breakage
You want a single container rather than committing to a full set
You are comfortable with BPA-free claims without specific polymer disclosure
The main thing to know
The polypropylene lids are the weakest link — Glasslock has not disclosed PFAS-free status for the lid gasket material, and the specific plastic formulation beyond "BPA-free" is not detailed.
Snapware does not disclose the specific plastic type used in the locking lid. While it is BPA-free, buyers who want full material transparency should consider Glasslock or Pyrex with known PP lids.
Skip this if you...
You want to eliminate all plastic from your food storage — the PP lids are direct food-contact surfaces
You need one-handed lid operation — the 4-tab locking system requires two hands
You specifically need PFAS-free verification on lid gaskets
You want full material transparency on lid composition — Snapware does not disclose the specific plastic type
You want borosilicate glass for better thermal shock resistance — this uses soda-lime glass
You prefer one-handed convenience — the 4-latch mechanism requires two hands
Neither of these quite what you're looking for?
