Please pay attention to the following points when using plastic wrap:

1. First, choose the kind that can be heated in a microwave oven (usually there will be instructions on the box).

2. If it is a plastic wrap that can be used in a microwave oven, try not to touch the food when sealing it on the bowl. Before heating, open a gap in the plastic wrap or poke a few holes in the plastic wrap. A small hole.

3. Even if you use plastic wrap in a microwave oven, do not heat it for too long, preferably no more than 4 minutes, otherwise it will partially melt (wrinkles and holes in the plastic wrap). If you need to heat for a longer time, please use a special microwave oven cover.
