The tableware labeled \ "No. 5 \" or PP is microwave oven tableware, which can be used in microwave oven and generally has no harm. When you put it in the microwave oven, you need to remove the cover. The only plastic box that can be put into the microwave oven can be reused after careful cleaning. It should be noted that for some microwave oven lunch boxes, the box body is indeed made of No. 5 PP, but the box cover is made of No. 1 PE. Because PE can not withstand high temperature, it can not be put into the microwave oven together with the box body. To be on the safe side, remove the lid before putting the container into the microwave oven.
