Why does the popcorn machine contain lead?

The popcorn machine is absolutely closed when working and baked at high temperature. So where does lead come from? It comes from the seal of the popcorn machine, not the body of the popcorn machine, because the cover must be resistant to high temperature and can seal the popcorn machine. Of course, lead, a soft and high-temperature resistant heavy metal, should be chosen. If you have any questions, send me a message with Baidu.
