Multipart label laminate, labels and labelling

Sealing a package with a visually transparent sealing label is described. The visually transparent sealing label contains an ultraviolet blocking component to prevent transmission of ultraviolet radiation through the label to the surface of the package. The package comprises an activatable component that upon excitation with ultraviolet radiation emits luminescence. The presence of the sealing label on the package may be verified by illuminating the sealing label with ultraviolet radiation and by observing whether the level of luminescence from the package material under the sealing label is lower than a limit value.
