PVB Constant Heat Vacuum Sealer

The PVB Constant Heat Vacuum Sealer has all the available features of our PB constant heat sealer, with the added capability of vacuum and gas flush for applications requiring modified atmosphere packaging (MAP). Unlike our other vacuum sealers that use a heat and cool cycle during sealing (impulse), the PVB is constantly heated seal jaws. Like the PB, the PVB is designed to vacuum seal MIL spec barrier bags, coated paper, film and foil laminates.
