Whether a paper takeout container can be heated in a microwave oven? | KaiLai Packaging
Whether a takeout container can be heated in a microwave oven primarily depends on its material. Generally speaking, most disposable takeout containers are not recommended for microwave heating.Disposable takeout containers are typically made of paper or plastic, with plastic containers having various materials. If the material of the container is polystyrene or polypropylene, among others, these materials may melt, deform, or even release harmful substances under high temperatures, posing potential hazards to food and human health.However, if the takeout container is made of PP5 (polypropylene) material and is marked with "PP" or a triangle arrow with the number "5" on it, then this type of container can be safely heated in a microwave oven. PP5 material has good heat resistance and can withstand the high temperatures in a microwave oven.
