Abstract:
1. A process for aseptic packaging a sterile liquid into packages, the packages being made of a strip of flexible material, folded and flattened, to form a sequence of chambers or compartments, which will finally form the packages, the process comprising: pressuring a pre-chamber, which is arranged upstream with respect to a chamber to be filled with the sterile liquid, with a sterilized inert fluid by injecting the sterilized inert fluid through an auxiliary line, which reaches only into the pre-chamber, for activating a sterile barrier allowing complete asepsis of the packaging process; compressing the flexible material between the pre-chamber and the chamber by a pressing device to form a seal against an outer surface of a tube for feeding the sterile liquid into the chamber; introducing the sterile liquid into the chamber via the tube; and transverse sealing a lower part of the chamber by a transverse sealing device.
