Zusammenfassung:	The invention concerns a covering and/or sealing film for a pack, in particular a blister pack, configured to seal at least one filling product chamber and allow opening access to the filling product chamber by separation and/or tearing, wherein the film, in particular in the area of the filling product chamber, has a predetermined electrical conductance property (C14) which can be contacted for electronic analysis and as a reaction to separation or tearing undergoes an evaluatable change, wherein the film, at least in sections, has a capacitatively active, contactable layer structure, the electrical capacitance of which undergoes a change by the tearing or separation.
