What is Food Grade Silicone and Why is it Better Than Single-Use Plastic?

Single-use plastics were made for convenience, but there’s no question that single-use plastic is harmful to the environment and our bodies. Americans use 100 Billion plastic bags per year with only 1% of those being recycled. The rest? They end up in landfills where it takes over 500 years for each of those bags to break down. The good news is, we here at Stasher are committed to eliminating the need for single-use plastics around the world and it's the reason why we created the world’s first endlessly reusable silicone bag with a patented Pinch-Loc seal.

Never heard of platinum, food grade silicone or wondering what the difference is between it and single-use plastics? We break it down for you below. 

Benefits of food grade silicone:

  • Highly resistant to damage and degradation from extreme temperatures
  • If cared for properly, it won’t harden, crack, peel, crumble, dry out, rot or become brittle over time
  • Lightweight, saves space, easy to transport
  • Non-toxic and odorless – contains no BPA, latex, lead, or phthalates
  • Stasher bags are recyclable through our partnership with TerraCycle

What is plastic made of? 

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 better alternative. Food grade silicone, which is what Stasher bags are made entirely of, is a more versatile, durable, and safer alternative to single-use plastic. Unique by design, Stasher was created as an easy-to-use and endlessly reusable alternative to single-use plastic.

    What is food grade silicone?

    Our Stasher bags are made from platinum-grade silicone that meets FDA and EU requirements for food contact and safety. Silicone is made from alternating silica and oxygen molecules. The silicone that makes up our Stasher bags is made from these foundational elements and combined with carbon to create a raw silicone product. This material is then cured under heat and pressure to create the silicone parts that are sturdy, inert and versatile.

    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 bags make it easy to store your food at home or on-the-go while keeping what you’re eating away from plastic.

    Is silicone recyclable? 

    Yes. Check your local recycling center for information on silicone recycling options. Better yet, if your Stasher bag is damaged or has reached the end of its life you can recycle it by sending it back to us! We’ve partnered with TerraCycle to recycle our damaged Stasher bags into an entirely new and useful product such as playground or track surfaces.

    Is silicone safe for food? 

    Our silicone Stasher bags are as pure as glass. It’s safe to store food, put in the microwave, freezer, oven, and dishwasher. You can even cook right in your Stasher bag, sous vide style. It won’t leak, break down, or degrade over time.

    Is silicone BPA free? 

    Food grade silicone, the material we use to make Stasher bags, is free of chemicals like BPA, BPS, and other phthalates. 

    Is silicone better than single-use plastic? 

    We think so, and the FDA even stated that raw materials which go into making silicone are safe for food grade applications. But let’s be honest: while silicone replacements alone won’t fix our global single-use plastic problems, swapping single-use items for reusables is a step in the right direction. 

    To date, our Stasher Squad has prevented more than one billion (and counting) single-use plastic bags from entering our waste stream.

    Is silicone safe to cook with? 

    Yes. Stasher bag’s food grade silicone can be used throughout your kitchen: microwaved, baked in the oven up to 425 degrees, even thrown in your dishwasher for easy cleaning with the rest of your dishes. You can freeze them, and hey — Stasher bags can be safely used to sous vide!
