Can plastic lunch boxes be microwaved?

Microwave lunch boxes are usually made of PP and PS plastics. PP refers to polypropylene, which has good mechanical and thermal properties and is used in various performance laminates and packaging materials. PS is commonly known as hard glue, ordinary hard glue, which is hard and brittle. When beating, it emits a metal-like "ding" sound, and the sound is crisp, commonly known as "sound glue", non-toxic and tasteless. This kind of material can be used for packaging, and it is non-toxic and tasteless, and it is also very good to use. The lunch box made of PP is softer, while the lunch box added with PS is slightly harder, and there is no difference in other aspects.

These two materials can also be heated in a microwave oven without releasing toxic substances. It should be noted that the general lunch box is marked whether it is suitable for microwave oven use. The lid material of some lunch boxes is not PP, so it cannot be heated in a microwave oven. Do not take the lid off when the rice is hot.

If it is a plastic lunch box with neither marked material nor "Microwave Suitable" or similar content, it cannot be heated in the microwave oven. Such a lunch box may be of inferior quality, so do not use it in a microwave oven.
