b) Whether the packaged items need to be filled with other protective gases. A multi-functional food vacuum packaging machine with an inflator can be selected.
c) Requirements for the vacuum of the packaged item. If the packaged items need to be stored under high vacuum conditions, you need to choose a cavity vacuum packaging machine.

When purchasing, the packaging of solid and granules is relatively dry and non-corrosive. It can be made of aluminum alloy, and the package is filled with soup. For materials with high salt and acid content, stainless steel or aluminum-magnesium alloy can be used. . The sealing ring is generally made of silicone rubber and black rubber. A few low-grade products use foam rubber. The silicone rubber has high temperature resistance, corrosion resistance, good sealing performance and long service life. The foam rubber has poor sealing performance, easy to fall off and short service life.
