Only PP material can be heated
Plastic lunch box standard has 1 (PET), 5 (PP), 6 (PS) these 3 kinds - PET heat resistance degree is only 70℃, PS heat resistance degree is only 90℃, and PP material heat resistance degree is 130℃, melting point is as high as 200℃.
So generally only No.5 PP material plastic can be put into the microwave oven to heat.
2. Precautions for the use of plastic lunch boxes
① Take off the lid of the lunch box when heating
Some microwave lunch boxes, the box body is made of No.5 PP, but the lid is made of No.4 PE, and PE is not able to withstand high temperature. So take the lid off before you put it in the microwave.

Due to cost control and other reasons, usually disposable lunch boxes do not have very high safety standards. The purpose of their production is to contain once, high temperature, and possibly oil food. It is safe to use under this condition.

PE material is a very broad concept, in order to suit different use scenarios, will use different ingredients and production processes. There are sealed bags with logo. This will lead to their residues, tolerance temperature, strength, hardness and other aspects have a big gap, so can not see the PE label can be used to store food.
