Abstract: A method, comprising: providing a combination of a package and a label attached to the package, wherein the label comprises a fluorescent substance, illuminating the label with excitation light so as to cause the label to emit fluorescence light, capturing an image of the label by using an imaging unit, and detecting the position of the label by analyzing the captured image and/or detecting a degree of adhesion of the label by analyzing the captured image.

Abstract: The invention relates to a multipart label laminate for labelling of single-use sterilization packs, the multipart label laminate comprising a face layer, a first adhesive layer of acrylic based pressure sensitive adhesive, a carrier, a second adhesive layer of acrylic based pressure sensitive adhesive, a liner, and a printing ink layer between the carrier and the second adhesive layer. The invention further relates to a method for application of a multipart label.

Abstract: 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.

Abstract: A sealing label suitable for sealing a package made of varnished cardboard comprises: a carrier layer, and an adhesive layer, wherein the thickness of the carrier layer, the material of the carrier layer, and the composition of the adhesive layer have been selected such that: a minimum deformation force of the label is smaller than a first breaking force needed to break the cardboard material of the varnished cardboard, a minimum detaching force of the label is greater than the first breaking force, and the minimum detaching force is smaller than a second breaking force needed to break the label, wherein the first breaking force is a first pulling force which causes breaking of the cardboard material in a situation where the label is separated from the varnished cardboard by pulling the label with said first pulling force, and the minimum detaching force is a second pulling force which is needed to separate the adhesive layer of the label from the surface of the varnished cardboard in a situation where
