Lifting external vacuum packaging machine is vacuum or nitrogen-filled sealing packaging for electronic components, hardware, meat, dry goods, cloth wool products, whole grains, vegetables and fruits, pharmaceuticals, plastic raw materials, food, chemical raw materials, etc. It can achieve anti-oxidation, anti-corrosion, anti-mildew, moisture-proof and other fresh-keeping and quality-preserving effects. Lifting external vacuum packaging machine adopts no vacuum chamber, and the air nozzle directly vacuums or fills the packaging bag with nitrogen. The size of the packaging is limited, and it occupies a small space.This machine adopts long air nozzle design, and the air nozzle length can be adjusted freely from 0--200MM. In addition to the automatic lift transmission design, just press the lift switch. Automatically raise or lower to the appropriate vacuum position, so that the pumping and inflation speed is fast, the work efficiency is high, and the operation is simple and convenient.
