摘要： A method for forming sealed partially-filled packages filled with a pourable product comprises at least forming a tube from a web of packaging material, filling the pourable product into the tube for forming a product column within the tube, directing a sterile gas into the product column for forming and/or maintaining a gas cushion within the product column, and forming and transversally sealing the tube, for obtaining the packages containing the pourable product and a gas space formed from a defined volume of the sterile gas originating from the gas cushion.
