1.The external vacuum packaging machine is used for vacuum packaging of various electronic products (semiconductors, circuit boards, electronic products, etc.) and machined metal parts to prevent moisture and oxidation. It is used for vacuum packaging of fabrics, cotton and wool products to reduce the packaging volume and save logistics costs. It is used for vacuum packaging of seafood, fruits, tea, salted goods, soy products, etc. in food to prevent oxidative deterioration and prolong the shelf life. It is filled with protective gas such as nitrogen and carbon dioxide to keep it fresh and preserved, and it can be protected from impact.

2.The packaging materials applicable to this machine are various composite films such as polyester/polyethylene, nylon/polyethylene, polypropylene polyethylene, polyester/aluminum foil/polyethylene, nylon/aluminum foil/polyethylene and other composite materials. The goods packed by this machine have the characteristics of moisture-proof, mildew-proof, insect-proof, pollution-proof, oxidation-proof, volume-saving, freight-saving, prolonging the storage period, and guaranteeing the quality of the goods.

The biggest feature of this machine is that it is not limited by the size and volume of the packages, and it can be packed in vacuum or nitrogen arbitrarily with a wide range of applicability, high economic efficiency, and very convenient to use.

The machine has the advantages of compact structure, small volume, light weight, power consumption, high sensitivity, easy operation and maintenance.
