The modern urban lifestyle is busy with work schedules and limited time, which makes it crucial for families like ours to carefully pack lunch boxes in order to have more time to rest during the noon break. When these meals cool down, they need to be reheated using a microwave. Are microwave-heated bento boxes safe?

In 1988, the American Plastics Industry Association came up with a bunch of recycling symbols for plastics. You know, those little triangles with numbers and letters on them that you see on plastic stuff like lunch boxes. Well, there are seven main types of plastic we use every day, but only one can handle the heat from a microwave. That's PP polypropylene plastic bento box! It's also known as No. 5 environmentally friendly plastic PP and it's super stable chemically. It can even take temperatures up to 200°C without breaking a sweat! This is what our daily plastic lunch boxes and cups are made of - they're colorless, non-toxic, and perfect for heating food in the microwave.

This material is also known as No. 5 eco-friendly plastic PP, which has more stable chemical properties and can even withstand high temperatures up to 200°C. It's colorless, non-toxic, and commonly used in our everyday plastic lunch boxes, cups, and other disposable or non-disposable tableware. It's the only type of plastic that can safely handle hot food and be heated in the microwave oven.
