ABSTRACT:
A method for operating a package emptying station having a work station, in which an emptying step is performed, an inlet via which the package to be emptied is inserted into the work station, an outlet via which the emptied package is ejected, and a product outlet through which the emptied contents of the package is discharged. Continuous tubular film packs are provided both at the inlet and also at the package outlet which seal off the inlet and the outlet and encase the package to be emptied or the emptied package during the insertion or corresponding ejection of the package. The film is sealed off and severed between individual packages such that the interior and the exterior do not come into contact. In this manner, both contamination of the package contents by environmental substances and also any contamination of the environment by the package contents can be avoided.
