The sealing film (6) comprises a layer structure including a first electrical conductive layer (26), a second electrical conductive layer (27) and an electrical insulating layer (28) that is arranged between the first electrical conductive layer and the second electrical conductive layer, where the layer structure forms a capacitor (30). The electrical insulating layer has a property that affects the capacitance of the capacitor, where the property is changed by an energy input into the sealing film. A grip tab is formed in the electrical conductive layers of the layer structure. The sealing film (6) comprises a layer structure including a first electrical conductive layer (26), a second electrical conductive layer (27) and an electrical insulating layer (28) that is arranged between the first electrical conductive layer and the second electrical conductive layer, where the layer structure forms a capacitor (30). The electrical insulating layer has a property that affects the capacitance of the capacitor, where the property is changed by an energy input into the sealing film, and a layer thickness of the electrical insulating layer is changed according to the property of the electrically insulating layer. A grip tab is formed in the electrical conductive layers of the layer structure. Independent claims are included for: (1) a device for checking the sealing of the opening of glass vessels; and (2) a method for checking of the sealing of the opening of glass vessels. |
