In busy modern life, plastic bento boxes are first choices for many due to their lightness and practicality. Are plastic bento boxes microwavable? Many people ask such questions. Indeed, besides convenience, there’s health and safety. This article will give detailed answers to help use plastic bento boxes correctly.

Classification of plastic bento boxes

According to the type of material used, most plastic bento boxes cannot be put into a microwave. Here are the common plastic materials used:

  • PP (Polypropylene): Normally marked with the “No. 5” logo, this is one of the common materials for microwave-friendly plastics. High-temperature resistance can go up to 120°C.
  • PE (Polyethylene): PE would most probably be used in freezer boxes, as it generally has very poor heat resistance and is not suitable for heating in a microwave.
  • PET (polyethylene terephthalate):  It’s in common usage for disposable plastic packaging and is unsafe for use in the microwave.

You may check the logo at the bottom of plastic bento boxes, such as “Microwave Safe” or “No. 5 PP” to see if the material is applicable for the microwave.

Safety of plastic lunch boxes in microwave ovens

The main defects of plastics are that they can emit harmful substances such as bisphenol A (BPA) when used in high-temperature environments and may even contaminate food. Therefore, using plastic lunch boxes for heating requires the following attention:

  • Choose material with food uses: Ensure the lunch box does not contain harmful chemicals like BPA.
  • مقاومة درجات الحرارة العالية: Plastic can bear the high temperature in the microwave oven.

Besides, high-sugar and high-oil food can make the microwave oven locally overheated, which quickens the decomposition of plastics. Therefore, such kind of food should be heated in caution.
