Silicone is an environmentally friendly material that is resistant to high temperatures, corrosion, and wear. Therefore, silicone lunch boxes can be reused and are not easily deformed or broken. Compared with traditional plastic lunch boxes, silicone lunch boxes are more durable and can be used multiple times, reducing environmental pollution. In addition, silicone lunch boxes also have the advantages of good sealing and easy cleaning, making them very suitable for use as lunch boxes.
