Yes.

Microwave lunchboxes are usually made of PP and PS plastics. ?PP is polypropylene with excellent mechanical and thermal properties, and can be used for laminates and packaging materials with a variety of properties.

PS is often referred to as hard rubber, plain hard rubber, hard and brittle. When it is tapped, it makes a metallic "ding-dong" sound and produces a crisp sound. This material can be used for packaging, non-toxic and odorless, safe to use. PP lunch box is relatively soft, while PS lunch box is slightly hard, in other aspects there is no difference.

These two materials are also safe to heat in the microwave, and will not release toxic substances, it should be noted that the general lunch box is labeled whether it is suitable for use in the microwave oven, and some lunch boxes have lids made of materials that are not PP, and therefore can not be put in the microwave oven to heat up the hot meal, it is best to not take the lid.

If there is no labeling material and no "microwaveable" and similar content of the plastic lunch box can not be placed in the microwave oven to heat. Such a lunch box may be poor quality lunch box, it is best not to put into the microwave oven to use.
