A form-fill-seal machine and a method for manufacturing and filling a bag () having a drawstring tape or cord. The form-fill-seal machine includes a device to guide a film on the machine. A conveying device positions at least one drawstring tape or cord on the film. A folding device folds the film to form a first sheet and a second sheet of the bag. First and second welding jaws weld the first sheet and the second sheet to close two sides of the bag and leave a third side of the bag open. A filling chute fills the bag by the third side of the bag. Third welding jaws close the bag by sealing the third side.

Form fill and seal machine for a bag including a drawstring tape or cord and method for manufacturing such a bag

The invention relates to a method for manufacturing (S) a bag () by means of blown film extrusion, including the following steps: extruding (S) plastic such as to form an annular film () including closing assemblies (), said annular film being intended to form the walls of the bag; and blowing (S) the annular film such as to form a sheath, the complementary profile sections () of each of the closing assemblies () being integrally formed with a base () connected to the annular film () via a connection rod () that extends parallel to the longitudinal axis (X) between the annular film () and the base () and is designed to keep the base () separated from the annular film ().
