The Firawer Silicone Storage Bags offer a middle-tier solution that combines the benefits of 100% food-grade silicone with a secure rigid slider closure. The platinum-cured silicone body provides excellent thermal stability, making these bags safe for everything from freezer storage to boiling water for sous-vide. With a wall thickness of approximately 1.5mm, the bags are robust enough to resist punctures while remaining flexible enough to "burp" out excess air before sealing.
The sealing interface uses a plastic slider bar that creates a hermetic, leak-resistant seal. This mechanism is highly effective for containing liquids, though it does require a specific technique to operate smoothly. If the slider becomes difficult to move, especially when wet, a very light coating of food-grade oil on the bag's top track can reduce friction. It is important to note that while the silicone bags can handle high heat, the plastic slider bars should be kept away from stovetops and high-heat dishwasher settings to avoid melting or warping.
Practical Usage Notes
Because the corners of these bags can be prone to lipid or residue buildup, using a bottle brush during cleaning is recommended to ensure thorough sanitation. Like most silicone products, these can be stained by high-pigment foods like turmeric or tomato sauce, though this is an aesthetic change and does not impact the bag's safety or function. The set includes three useful sizes: 32oz, 18oz, and 8oz.
- Platinum-cured silicone ensures no chemical leaching even during high-heat use.
- The rigid slider mechanism provides a superior seal compared to basic pinch-locks.
- Versatile temperature range from -50°C to 230°C for the silicone vessel.
If you prefer an integrated seal that doesn't use separate plastic sliders, you may like the Stasher 4-pack.
