Single Chamber Vacuum Packaging Machine Vacuum packaging machine is a new type of vacuum packaging machine. It can automatically seal the packaging bag immediately after it is vacuumized. The vacuum degree in the bag is high, the residual air is small, and the reproduction of bacteria and other microorganisms is inhibited. The oxidation, mildew and corruption of articles are avoided. At the same time, the packaging volume of some soft articles can be reduced after packaging, which is convenient for transportation and storage. DZ-400 series vacuum packaging machine is a novel packaging machine. It automatically seals the bag after it is vacuumed. The vacuum inside the bag is high and the residual air is small.It inhibits the proliferation of microorganisms such as bacteria, avoids the mildew and spoilage of articles, and at the same time, for some soft articles, after packaging, it can reduce the packaging volume and facilitate transportation and storage. This series of vacuum packaging machines use composite film bags to heat seal all kinds of solid, powder, paste and liquid of all kinds of food, medicine, local products,aquatic products, chemical raw materials, hardware and electronic components. It can effectively prevent the spoilage and deterioration caused by lipid oxidation and aerobic bacteria reproduction, and achieve quality, preservation, taste and color preservation, so as to prolong the period Storage time, easy transportation and export of packed goods. There are two colors of the buttons on the control panel of this machine, and the two are shipped randomly. Specification: Minimum absolute pressure of the vacuum chamber
