The takeaway lunch box can be heated directly in the microwave, but it depends on the material.

Takeaway lunch boxes with pp5 on the bottom can be heated directly in the microwave, but those made of other materials cannot. Generally speaking, most takeout boxes are made of plastic or paper boxes. The plastic must have pp5 printed on the bottom to be considered a safe and heatable material. Microwave heating of other materials is not recommended.

It is safe to store food, but it does not mean it is safe to heat. Among these plastic packaging boxes, only No. 5 plastic polypropylene (PP) can go into the microwave oven. Polypropylene is relatively heat-resistant and can withstand temperatures of around 200 degrees.

So it can be heated in the microwave and repeated heating will not cause any big problems. The heat resistance of other plastics is much worse. It is best not to heat it directly or hold food that is too hot. Of course, it cannot be used repeatedly.

The role of take-out lunch boxes

The material of take-out lunch boxes is very important. Generally speaking, takeout lunch boxes are made of environmentally friendly materials, such as paper lunch boxes, corn starch lunch boxes, etc. These materials not only ensure the safety of food, but also effectively prevent the lunch box from deforming and leaking.

The sealing of takeaway lunch boxes is also very important. Generally speaking, takeout lunch boxes will adopt a sealed design, such as lock type, pressure cover type, etc. These designs can effectively prevent food leakage and contamination, while also maintaining the freshness and taste of food.

The heat preservation of takeaway lunch boxes is also very important. In order to ensure the temperature of the food, insulation materials, such as foam, air cushion, etc., are usually added to the take-out lunch boxes. These materials can effectively maintain the temperature of food, allowing consumers to enjoy hot meals when receiving takeaway food.
