What is food grade silicone?

What is food grade silicone?

Sure, plastic is convenient and easy to use, but there’s no question that it’s toxic to the environment and our bodies. Every day, 20 million plastic bags go to landfill in the u.S and it takes over 500 years for each of those bags to break down. There is a solution in stasher, the world’s first and only plastic-free storage bag, which is made out of pure platinum, food grade silicone.

Plastic that doesn’t end up in a landfill often ends up in the ocean and enters the food chain which is a big concern for human health. The harsh chemicals and toxins found in plastic can lead to cancer, infertility, immune disorders and more.

Fortunately, you now have a healthier option: food grade silicone is a more flexible, sustainable, and safer alternative to plastic, so it’s safe for people and the planet. Unique by design, stasher is engineered to get people to rethink the plastic in their lives. No other silicone bag delivers airtight performance and self-sealing convenience.

What is food grade silicone?

Food grade silicone is a non-toxic type of silicone that doesn’t contain any chemical fillers or byproducts, making it safe for use with food. Silicon, the naturally occurring chemical element that makes up silicone, is a metalloid, which means it has properties of both metals and non-metals and is the second most abundant element in the earth’s crust, after oxygen.

The silicone molecule is comprised of silicon, oxygen and quartz, a durable, hard, inflexible “rock”, which is the most common component of sand. Due to its resiliency, non-porous surface and sustainability, food grade silicone is essentially soft glass. While mason jars and other glass containers are great for plastic-free storage, they can break, take up a lot of space, and are inconvenient for taking on the go. Stasher makes it easy to store your food at home or on-the-go while keeping what you’re eating away from plastic.

Benefits of food grade silicone:

  • Highly resistant to damage and degradation from extreme temperatures
  • Resistant to rain, sleet, snow, and the sun’s uv rays
  • Doesn’t harden, crack, peel, crumble, dry out, rot or become brittle over time
  • Lightweight, saves space, easy to transport
  • Made from an abundant natural resource
  • Non-toxic and odorless – contains so bpa, latex, lead, phthalates,
  • May be 100% recycled at select locations; non-hazardous waste

C is for cooking

C is for cooking

We’re back with another installment of #stasheratoz! and this week, we’re showing you all of the different ways you can cook with stasher!

Every Wednesday we’re featuring a different letter of the alphabet, highlighting our favorite food or item to store in our stasher bag that starts with that letter.

Stasher is the ultimate multi-tasking bag! It freezes, it cooks, it serves, it packs, it washes, it saves money, it saves the planet and makes life easy!

Stasher’s innovative pinch-press seal is air-tight and helps keep food fresher longer. The seal combined with stasher’s non-porous surface helps inhibit bacterial growth.

Stasher is made of pure platinum silicone, so it’s a healthy alternative that’s safe for people and the planet. Overtime, plastic bags and containers leak harsh chemicals and toxins into your food, which ultimately end up in your body. With stasher you get all of the ease and convenience of plastic without any of the consequences.

So let’s get cooking! Here are all the ways you can cook with stasher:



Marinate in stasher to add flavor to your meat, fish, or vegetables without having to worry about leaks and spills.

Sous Vide



Sous vide is a method of cooking in which food is sealed in airtight bags then placed in water for longer than normal cooking times (usually 1 to 6 hours) at a regulated temperature much lower than normally used for cooking. The intent is to cook the item evenly, ensuring that the inside is properly cooked without overcooking the outside, and retain moisture. Traditionally, food is cooked in plastic when using the sous vide method. But when plastic is heated it accelerates the release of harmful chemicals that leech into your food. Instead, use our entirely plastic-free stasher bags that are made from food-safe, 100% pure platinum silicone.



Steam fresh or frozen veggies by placing them in stasher with olive oil and any herbs and spices. then place the bag in boiling water for about 10 minutes. Open carefully and enjoy! Using this method, you won’t lose any of the nutrients in the water and you won’t have to worry about your veggies tasting like plastic.


to reheat or steam fresh or frozen food in the microwave, simply leave your stasher bag open and handle with caution.


make meal prep easy and store meal portions in the fridge or freezer for future use or a quick and easy home-cooked meal. store a homemade pasta sauce made from summer tomatoes for a winter meal, or create your own healthy frozen dinner. stasher protects food from freezer burn and helps seal in freshness.


when you’re finished cooking, stasher can go straight into the dishwasher, making cleanup a breeze!
