The Role Of Vacuum Packing Machine

In addition to the oxygen and quality preservation functions of vacuum packing machine, it mainly has the functions of anti-stress, gas barrier and freshness. In addition, many foods are not suitable for and must be vacuum inflatable packaging. The vacuum packaging machine can effectively prevent the food from being crushed and deformed under pressure and does not affect the appearance and printing decoration of the packaging bag. Its nitrogen gas can inhibit the growth and reproduction of anaerobic bacteria, keep the freshness and color of fruits and vegetables, and high concentration of oxygen can keep fresh meat.

Most vacuum packing machine are externally pumped. As we all know, there are two modes of vacuum packaging. One is vacuum packaging and the other is inflatable packaging. Inflatable packaging will cause the packaging material to expand too much, so this function is not suitable On the machine with a built-in vacuum chamber, the external-extraction vacuum packaging machine has more advantages. Because there is no vacuum chamber in the external pumping vacuum packaging machine, a vacuum nozzle is extended on the side of the machine and placed in a vacuum container to complete the inflation process.

After the vacuum packing machine reaches the preset inflation value, the machine performs heat sealing. It is necessary to set the heat sealing time on the computer board. Take care not to take too long to avoid damage to the packaging materials. When the preset time is reached, the indicator light is off, then the vacuum chamber is connected to the atmosphere, the cover is lifted, and the inflatable packaging of the vacuum packaging machine is completed.
