How to use it

1. Fill the bag with your preferred food items, ensuring you do not exceed the max fill line for liquids.

3. Place in the microwave or oven (up to 200°C) for cooking or reheating purposes.
4. Store in the fridge or freezer; the airtight seal prevents freezer burn effectively.
5. To clean, place the bag on the top rack of your dishwasher or wash with warm soapy water.

FAQ

Is it safe to cook in a Stasher bag?

Yes, Stasher bags are made from platinum silicone which does not leach chemicals when heated. You can safely use them in boiling water for sous-vide, in the microwave, and even in a conventional oven up to 200 degrees Celsius without worrying about toxic emissions or melting.

Can the bags be recycled at the end of their life?

Yes, while silicone isn't accepted in standard UK kerbside recycling, Stasher runs a 'repurpose' programme. You can return damaged bags to the company where they are converted into playground pebbles or other industrial materials, ensuring they never end up in a landfill or the ocean.

Are Stasher bags leakproof for liquids like soup?

It depends on how they are stored. While the Pinch-Loc seal is highly water-tight and airtight, the bag can leak if it is squeezed under heavy pressure while filled with liquid. For transporting soups, it is best to keep the bag upright in your bag or container.
