The invention refers to a container precursor (100), comprising a wall of glass (101) which at least partially encloses an interior volume (102) of the container precursor (100)； wherein, on a side of the wall of glass (101) which faces away from the interior volume (102), the wall of glass (101) is at least partially superimposed by a plurality of particles (1201). Further, the invention refers to an arrangement (200), comprising a packaging and a multitude of the container precursors (100)； to a process (400) for preparing a functionalised container precursor； to a functionalised container precursor, obtainable by that process (400)； to a container (500)； to a process (600) for preparing a functionalised container； to a functionalised container, obtainable by that process (600)； to a closed container (700)； to a process (800) for packaging a pharmaceutical composition (701)； to a closed container obtainable by this process (800)； and to uses of a container precursor (100) for making a packaging container, of a container (500) for packaging a pharmaceutical composition (701), and of a plurality of particles (1201).
