People's understanding of vacuum packaging machines is rather simplistic. They only know that vacuum packaging machines can seal plastic bags and also perform vacuuming. And both of these functions are carried out automatically. Therefore, some people think that all vacuum packaging machines can be called [automatic vacuum packaging machines]. Of course, this statement makes some sense. In fact, the [automatic vacuum packaging machines] mentioned in the industry are not like this. The true meaning of automatic vacuum packaging specifically refers to the following three types:
1. Automatic lid-lifting vacuum packaging machine
