Does the cover film of the heating tray in a microwave oven crack during heating?
Thread Content
As people’s living standards improve, microwave ovens have become common in households. The coating film used on the heating chamber of microwave ovens is usually made of polyethylene. There has been concern that, under the high temperatures generated by microwave heating, this polyethylene film might crack. This raises the question of whether consuming food that has been heated in such microwaves could have an impact on human health I would like to ask everyone if this problem exists Thank you!
The thermal decomposition temperature of polyethylene is above 340 degrees, so the likelihood of it decomposing in a microwave oven is low. In comparison, PVC is far inferior.
Don’t worry; as far as I know, its membrane is not polyethylene either
This is not a matter of unnecessary worry. I often buy products like plastic wrap at supermarkets, and the sales staff frequently recommend certain items to customers; I’ve experienced situations where I made the wrong purchase myself. Therefore, it is still recommended to choose carefully (buy branded products) and read the instructions carefully before use.
Never use PVC; PE is more reliable
May I ask, if a microwave keeps heating, can the temperature keep rising continuously?
Do not use a microwave to heat bucket noodles; I’ve tried doing that before and it gave off a plastic smell
