About The Stasher Brand

Stasher is a mission-led brand aiming to prevent single-use plastic bags from polluting the environment. Founded in 2005, Stasher’s website states they have sold millions of bags and prevented over 1 billion single-use plastic bags from entering oceans and landfills. The company also has a repurposing program in partnership with TerraCycle. They turn the used silicone bags into useful products, such as track surfaces and playgrounds. 

Founder of the Stasher brand, Kat Nouri, decided to create this line of reusable products to reduce her family’s single-use plastic waste. Her experience designing and developing silicone textiles allowed her to produce the first patented, self-sealing storage bag made from platinum silicone. The bags are designed in California but manufactured in China. 

Customer Feedback

Overall, customers are satisfied after purchasing a Stasher reusable silicone bag. They like the eco-friendly aspect of the bags and report they are easy to clean, compact, and easy to reuse. The bags also stay sealed and are durable. 

Common review complaints include:

  • The bags can take a long time to dry after washing 
  • They purchased the wrong size and not all bags can fit sandwiches
  • It can be hard to keep sandwiches together  
  • They are expensive compared to disposable plastic bags

When purchasing Stasher bags, Amazon and the Stasher Bag website are two popular vendors. Looking at 19 products on Amazon for a total of 29,492 ratings and 582 reviews, Stasher has an average rating of 4.6 out of 5.


Stasher bags have an easy seal you pinch close to keep food and leftovers airtight and fresh. The design ensures no leaking or spillage even when filling it with water. Their website features 9 different size bags, ranging from pocket-sized to stand-up mega bags. They also come in various colors, including lavender, red, orange, blue, and green. 

Since they are bags, it can be easier to clean with certain foods than others. For example, dry foods or liquids are easier to clean, including nuts or cereal. However, sticky foods, such as peanut butter or raw cookie dough, can be difficult to clean. You’ll also want to avoid storing smelly foods, such as garlic or marinades, as it can linger on the bag even after washing. 


Stasher regularly tests their material sourcing and comply with EU and FDA food-grade standards. When it comes to durability and safety, the platinum silicone material they use is high-quality. You can heat the bags in the oven, microwave, or boiling water without any toxic chemicals leaking into the bag’s contents. Even their material colors are made from food-safe colorants. 

The company claims their bags can be used for years. However, the thin construction can sometimes lead to accidentally poking holes in them. It’s still silicone material and not as durable as glass containers. 


While the Stasher website doesn’t indicate a warranty program, they do have a return policy. If you received a damaged product or simply want to return it, they will provide you with a prepaid return label for orders placed within 30 days. During the holiday season of November to December, free returns are available up to 60 days after purchase. 

Although not a warranty, you can send your used Stasher bags for recycling through their repurpose program with TerraCycle. This ensures you can give new life to the bags once they have reached the end of their life cycle. 

Notable Features

Here are some of the features you can expect to find when you purchase a Stasher bag.

Platinum-Grade Silicone

All Stasher bags are made from platinum-grade silicone, considered the highest quality of silicone. The bags also meet EU and FDA’s food contact and safety requirements since they are free of BPS, BPA, and other phthalates. 


While different sizes hold different amounts of food, the bag itself weighs hardly anything. This makes them very lightweight for carrying around compared to glass or plastic Tupperware. 

Waterproof seal 

All Stasher bags feature an airtight, waterproof seal that uses a push press system. This feature is Stasher’s patented Pinch-Loc seal. They are easy to open and close compared to Ziploc bags and reduce any leakage or spillage. 


Another result of the food-grade silicone used in Stasher bags is there is no lingering plastic odor. No weird taste from the material will leak onto your food when you store it in the bag.
