Compare Food Storage Containers
Stasher Platinum Silicone Reusable Storage Bag (Sandwich, Clear) 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.
Platinum-cured silicone is FDA and LFGB certified for food contact — no chemicals leach into food at any normal temperature. The material doesn't fit the rubric's standard glass/plastic categories, which affects the score.
BPA-free polypropylene lids are FDA-approved and safe at normal storage temperatures — a reliable plastic choice for food-contact lids.
The seal is integral platinum silicone — the same clean material as the bag body. No separate plastic lid component.
Confirmed BPA-free for both the glass containers and polypropylene lids.
Inherently BPA-free — platinum silicone contains no bisphenol compounds by material nature.
Pyrex has not published PFAS-free testing for the lid material — common across most brands in this category.
Stasher has not published a formal PFAS-free claim, though platinum silicone contains no fluoropolymers by material composition.
Oven-safe to 425°F in a preheated oven — suitable for reheating and light baking, but avoid broiling or rapid temperature changes.
Oven-safe to 425°F — versatile enough for most reheating and light cooking directly in the bag.
Snap-on lids push on without locking — adequate for refrigerator storage but will not prevent leaks during transport.
The patented Pinch-Loc seal provides positive snap engagement — leak-resistant for most uses, though Consumer Reports found silicone bag seals can leak under firm pressure.
Both glass containers and PP lids are dishwasher safe — containers on any rack, lids on the top rack.
The entire bag goes in the dishwasher as one piece — no disassembly, no separate lid to clean.
Simple one-handed snap lids lift on and off effortlessly — the easiest daily use in this comparison.
The Pinch-Loc seal requires a deliberate two-finger pinch — easy once you learn the technique but not as intuitive as snapping a rigid lid.
Containers stack flat when lidded — efficient for both fridge organization and cabinet storage.
Flexible silicone bags cannot stack rigidly like glass or plastic containers — they collapse when empty and don't hold shape when stored.
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 to eliminate single-use plastic bags and need a reusable silicone alternative
You care about having zero plastic contact with your food — platinum silicone is FDA and LFGB certified
You want a container that goes from freezer to oven to dishwasher in one piece
You value the lifetime warranty that covers the entire unibody bag
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.
This is a flexible silicone bag, not a rigid container — it cannot stack, is awkward to fill with liquids, and the Pinch-Loc seal takes practice to master. If you expect traditional container functionality, this is a different product category.
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 need rigid, stackable containers for organized meal prep
You want to store liquids — the flexible walls and Pinch-Loc seal can be awkward to fill and may leak under pressure
You prefer traditional container shapes for refrigerator organization
Neither of these quite what you're looking for?
