The Trudeau Stand Up Silicone Bags provide you with a more sustainable solution for packing up lunches or storing leftovers. Made in BPA-free, food-safe silicone, these have a solid stand-up base to give them maximum storage capacity. They're easy to clean, carry, and are space-saving too! Our silicone bags also have a double zip closure for serious security, holding in freshness and preventing any leaks or spillage. We've designed them in 6.5 oz, 12 oz, or 17 oz sizes so they can fit plenty of different foods, from nuts, sandwiches, fruits, veggies, and more. Want to heat up meals quickly? You won't have to transfer food to another plate as these are microwave and oven-safe, too, capable of withstanding up to 428F/220C temperatures. And for when you're ready to clean, simply place them in the dishwasher.
