Fast pumping speed: External vacuum packaging machines usually have a fast pumping speed, which can quickly evacuate the air inside the packaging bag and improve packaging efficiency.

• Unrestricted by space: Due to the flexible movement of the suction nozzle, the external vacuum packaging machine can be applied to packaging materials of various sizes and shapes without space limitations.

Multiple working modes: Many external vacuum packaging machines have multiple working modes, such as direct sealing, first vacuum and then sealing, first vacuum and then inflation and then sealing, etc., which can meet the needs of different users.

High degree of automation: Modern external vacuum packaging machines usually adopt advanced control technology, achieving full automation of vacuum packaging and reducing manual operation costs.

Scope of application of external vacuum packaging machine

External vacuum packaging machines are widely used in various fields, including but not limited to:

Food industry: Used for vacuum packaging of seafood, fruits, tea, salting, operation and maintenance to prevent oxidation and deterioration, and extend shelf life.

Electronics industry: used for vacuum packaging of products such as semiconductors, circuit boards, and electronic products to prevent moisture, oxidation, and discoloration.

Metal processing industry: used for vacuum packaging of metal parts to prevent rust and corrosion.

Textile industry: Used for vacuum packaging of fabrics, cotton and wool products to compress packaging volume and save logistics costs.

Operation and maintenance of external vacuum packaging machine

• Operation: When using the external vacuum packaging machine, it is necessary to follow the operating instructions for correct operation. Usually includes steps such as turning on the power, setting parameters, placing packaging bags and items, starting vacuuming and sealing.

• Maintenance: Regular maintenance and upkeep of equipment can extend its lifespan and ensure packaging quality. The maintenance includes cleaning equipment, checking the working status of vacuum pumps and solenoid valves, replacing vulnerable parts, etc.
