The packaging is in glass bottles with standard tinplate claw-type openable caps. For other special purposes, please consult the manufacturer.
The achievable function is to suck out the air inside the packaging container to reach the set negative pressure value (i.e., to create a vacuum), and then tighten the lid.
It is a semi-automatic model, where the bottles are manually inserted and removed, the caps are manually placed, and the other processes are automated.
