About Stasher

Stasher manufactures their products using platinum silicone sourced from responsible suppliers who meet strict environmental and labor standards. The company is certified as a B Corporation, demonstrating their commitment to balancing purpose and profit, and they donate a portion of sales to environmental nonprofits.

Key Features and Benefits
The Stasher Reusable Silicone Food Storage Bags stand out with several noteworthy features that contribute to both their environmental benefits and practical functionality:
100% Platinum Silicone Construction: Unlike some competitors that use plastic components or lower-grade silicone, Stasher bags are made from 100% food-grade platinum silicone. This material contains no BPA, BPS, phthalates, or other potentially harmful chemicals found in plastic alternatives. The silicone is non-porous, preventing bacterial growth and making it inherently more hygienic than plastic bags that can harbor bacteria in microscopic scratches and crevices.
Innovative Sealing Mechanism: The bags feature a pinch-lock seal system that creates an airtight, leakproof closure. This design improves upon the traditional zip-top mechanism by eliminating the common failure point of plastic zippers. In my testing, the seal remained completely watertight even when bags were filled with liquid and turned upside down or laid on their side in the refrigerator.
Temperature Versatility: One of the most impressive features is the wide temperature range these bags can withstand. They remain flexible and functional from -58°F to 425°F, making them suitable for freezer storage, refrigeration, sous vide cooking, and even oven use (without the sealing mechanism in the oven). This versatility eliminates the need for multiple specialized storage solutions.
Thoughtful Design Elements: The bags stand upright when filled, making them easier to fill than traditional plastic bags. The wide opening allows for easy access to contents, and the transparent material makes it simple to identify what’s stored inside. A writable label area on each bag allows for dating and content identification using a dry-erase marker.
Multiple Sizes and Bundle Options: The Stasher system includes multiple sizes: snack, sandwich, quart, and gallon. This range covers virtually all common food storage needs, from small portions of nuts or cut vegetables to large batch meals or marinating meats.
Compared to disposable plastic bags, the environmental impact reduction is substantial. The company estimates that each Stasher bag can replace up to 300+ disposable plastic bags over its lifetime. Given that Americans use approximately 100 billion plastic bags annually, with only about 1% being recycled, the potential for waste reduction is significant.
