Vacuum packaging machines can be divided into the following three categories according to their basic uses:
1. Food vacuum packaging machine. Such vacuum packaging machines should have a temperature control before vacuum packaging, and the equipment has its own cooling system, so it has high requirements for preservation.
2. Medical vacuum packaging machine.

(4) PLC control + liquid crystal display + high quality vacuum pump
These four kinds of matching are very wide in the market, but (4) PLC control + liquid crystal display + high quality vacuum pump is the most convenient operation, the degree of visualization is higher, and the maintenance rate is the lowest. This machine is most suitable for large or special items.
