Stainless steel does not absorb bacteria and filter chemicals, so when it comes to your health, storing your food in a stainless steel container can make you feel at ease. Stainless steel is non-stained and porous. These containers are safe for refrigerators, making them an excellent choice for leftovers or lunch.
No, stainless steel lunch boxes are not safe in the microwave. This is true of all metals, including stainless steel and tin foil. Metal functions like a mirror in a microwave oven, reflecting the light waves of the microwave oven, generating sparks and flames. If the electrical appliances are not turned off immediately, the microwave oven may even explode.
