ABSTRACT:
A method for the contamination-preventing transferring bulk material between a container having a flexible opening and a connecting tube using a tubular film is placed around the connecting tube; the tubular film is tied beyond the connecting tube leaving a free end of the tubular film beyond the tying point; the flexible opening and the tubular film are connected; the tying points of the outlet and the tubular film are untied, and the bulk material transferred; the free end of the tubular film, is constricted and additional tubular film is pulled from a tubular film supply until clean tubular film is available beyond the connecting tube; the tubular film is closed at two points in the clean section and cut in two between them; additional tubular film is pulled from the tubular film supply, and tied at a tying point located at a distance from the cutting point.
