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.
Pyrex-branded soda-lime glass is chemically inert and FDA-approved β the same proven glass used in Pyrex Simply Store containers.
Platinum-cured silicone is FDA and LFGB certified for food contact β 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.
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.
The seal is integral platinum silicone β the same clean material as the bag body. No separate plastic lid component.
Confirmed BPA-free for both the glass container and plastic lid components.
Inherently BPA-free β platinum silicone contains no bisphenol compounds by material nature.
Snapware has not published PFAS-free testing for the lid seal β 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 425Β°F β handles reheating, baking, and roasting with the lid removed. Avoid sudden temperature changes.
Oven-safe to 425Β°F β versatile enough for most reheating and light cooking directly in the bag.
Four-latch locking system with silicone seal creates a fully leakproof, airtight closure β safe for soups and liquids during transport.
The patented Pinch-Loc seal provides positive snap engagement β leak-resistant for most uses, though Consumer Reports found silicone bag seals can leak under firm pressure.
Both glass container and lid are fully dishwasher safe.
The entire bag goes in the dishwasher as one piece β no disassembly, no separate lid to clean.
Four locking tabs require two hands to open and close β slightly frustrating for quick refrigerator access but necessary for the leakproof seal.
The Pinch-Loc seal requires a deliberate two-finger pinch β easy once you learn the technique but not as intuitive as snapping a rigid lid.
Rectangular containers stack neatly in the fridge and cabinet.
Flexible silicone bags cannot stack rigidly like glass or plastic containers β 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 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
You want to eliminate single-use plastic bags and need a reusable silicone alternative
You care about having zero plastic contact with your food β 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
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.
This is a flexible silicone bag, not a rigid container β 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 want full material transparency on lid composition β Snapware does not disclose the specific plastic type
You want borosilicate glass for better thermal shock resistance β this uses soda-lime glass
You prefer one-handed convenience β the 4-latch mechanism requires two hands
You need rigid, stackable containers for organized meal prep
You want to store liquids β 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
