Can food grade packaging bags be heated in microwave oven

source:other news release time:2022-10-12 Hits:

　　1. The sealed bag is heated in the microwave oven. If the air pressure in the bag is too high, it will explode! The instructions of the microwave oven are all available (as well as eggs, which need to be poked). The microwave food I often eat can also be packed in plastic bags, but there is always a place to vent

　　2. Material problem of packaging bag

　　Generally, the bags in contact with food should be made of polyethylene (non-toxic, burning with the smell of candle oil), and generally resistant to 130 ℃. This kind of bag is OK (including the fresh-keeping bags and films bought in regular supermarkets)

　　However, many cheap bags (such as the vest bag in the vegetable market and the plastic bag given at the cash register in the supermarket) are made of PVC and cannot contact with food; Not to mention the ones made of recycled plastics (features: cheap, strong taste, burning with a foul smell)

　　Also, even if it is made of polyethylene, do not heat it with high oil food
