The DZ-350 MD vacuum sealing machine is a single seal bar unit designed for sealing contents in vacuum pouches. It is equipped with an electronic pressure sensor to assure steady control of the vacuum function. The DZ-350 MD vacuum sealing machine is available with a digital control panel that is user programable for vacuum cycle timing, seal bar temperature and cool down (evacuation duration) for very easy operation. The DZ-350 MD Vacuum Sealing Machine has a wide, long, 5 inch deep vacuum chamber that will accomodate very large packages or several small packages in one sealing cycle. With a 13.7 inch by .31 inch seal bar, it is possible to seal as many as four small pouches in one operation greatly increasing productivity. Additionally, a letter and number kit is included which will allow date and text message identification to be embedded in the seal of each package. A great way to set "freshness" markings.
