"Can you microwave silicone?" "Can you put silicone in the microwave?" "Is silicone microwave safe?" We receive these questions a lot! Many people are understandably cautious when reheating food, especially with widespread recommendations to limit the use of certain plastics.
The good news is that high-quality food-grade silicone, such as moonmoon's, is completely microwave safe. Made from platinum-cured, BPA-free silicone, it can withstand temperatures up to 230°C without melting, releasing odours, or leaching unwanted substances into food. In this guide, we'll cover everything you need to know, including safe microwave use, how silicone compares with other materials, common misconceptions, and practical tips for everyday use.
What makes moonmoon's silicone bags microwave safe?
Moonmoon's silicone food bags are made from food-grade platinum silicone. The material remains stable and non-reactive when heated, and the bags can be left slightly open to allow steam to vent safely during reheating. They're also completely PFAS-free.
How to microwave silicone bags: simple steps
Portion leftovers like soup, rice, or veg into a moonmoon bag.
Loosen the opening slightly for steam.
Microwave and stir half way/add water if needed.
Rest 1 min before opening. No plate splashes or warping.
Silicone beats plastic hands down
Plastic heats unevenly, sheds microplastics, and leaches BPA. Silicone remains stable, protecting meals. You can use one bag thousands of times instead of using disposables. Unlike many plastics, which can warp, degrade or release unwanted chemicals when exposed to heat, food-grade silicone remains stable across a wide temperature range. Some plastic containers may also shed microplastics over time, particularly when repeatedly heated, scratched or worn. While BPA-free plastics are now common, concerns remain about other additives that can migrate into food under certain conditions.
Food-grade platinum silicone is non-reactive, durable, and designed to withstand repeated heating and cooling without breaking down. This helps protect the taste and quality of your food while providing a safer, longer-lasting alternative for everyday use.
There's also an environmental benefit: a reusable silicone food bag can replace hundreds or even thousands of disposable plastic bags over its lifetime, helping to reduce household waste and single-use plastic consumption.
Heat uses beyond the microwave
Silicone food bags are incredibly versatile and can be used throughout the kitchen, not just for reheating leftovers. They are oven-safe up to 220°C, making them ideal for roasting vegetables, baking portions, or gently cooking proteins. They can also go straight into the freezer, where they lay flat for space-saving meal prep, batch cooking, and ingredient storage.
Food-grade silicone is also suitable for boiling and steaming, making it a convenient option for cooking fish, chicken, vegetables, and other delicate foods while retaining moisture and flavour.
Smaller bags are perfect for storing and reheating dips, sauces, dressings, baby food, snacks, and portioned ingredients. Because silicone is flexible, durable, and resistant to temperature extremes, the same bag can move seamlessly from freezer to microwave, oven, or dishwasher without needing to transfer food between containers.
