Chamber Vacuum Machine Purchase Skills:
When purchasing a chamber vacuum machine, aluminum alloy materials can be selected for packaging solids, granules and other dry and non-corrosive materials.
For packaging with soup, materials with high salt and acid content, a chamber vacuum machine made of stainless steel or aluminum-magnesium alloy can be used.
The sealing ring of the chamber vacuum machine is generally made of silicone rubber, black rubber, and a few low-grade products use foamed rubber.
