The Semi-Automatic Bag Welding Machines are used in situations, where bags have to be sealed tight after the filling process. The semi-automatic bag welding machine allows the operator to carry out an easy closing of the bag with impulse sealing or ATEX aproved heat-sealing. With the fact that the process can be started with a foot switch, the operator has both hands free to hold and stretch the bag flat. So we can avoid critical folds. Those Semi-Automatic Bag Welding Machines are commonly used in combination with conveying systems.
