Patent attributes
A sealing label suitable for sealing a package made of varnished cardboard comprises:a carrier layer, andan 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, andthe 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 the label is pulled with said second pulling force.
