An inert gas is a gas which does not undergo chemical reactions under a set of given conditions. The noble gases often do not react with many substances. Inert gases are used generally to avoid unwanted chemical reactions degrading a sample. These undesirable chemical reactions are often oxidation and hydrolysis reactions with the oxygen and moisture in air. The term inert gas is context-dependent because several of the noble gases can be made to react under certain conditions.
For a packaging machine a process and apparatus are provided whereby simultaneous with product discharged into the interior of the bag during the filling segment of the form, fill and seal cycle, a gas is also discharged into the interior of the bag to purge the interior of the bag and further, a low pressure area is created within the interior of the bag to remove excess purging gas and/or condensing fluids from the interior of the bag prior to sealing the bag. While considering the current packing trend and huge demand for sealing machine with gas flushing (gas flashing) system. EEWA developed and introduced these systems in the machine with latest technology.
