Abstract: The present invention relates to an adhesive security tape and to a method for its production. The adhesive security tape comprises first and second substrate layers that are connected to each other by means of a second adhesive layer and which can be attached by means of a first adhesive layer to an adhesive surface. The first substrate layer 2 has severing lines that completely penetrate at least part of the first substrate layer along the severing lines. The severing lines are preferably created with a laser beam, and the profile of the severing lines is designed so that the severing lines constitute an identifier.

Abstract: The invention relates to an adhesive safety strap 1 and a method for its production, wherein a given length is separated from an adhesive packaging band with a carrier layer 2 made from a material that can be processed with a laser and an adhesive layer 3, in order to form an adhesive strap; and a slot geometry, which cuts completely through the carrier layer 2, is formed in this adhesive strap by means of a laser after being attached to a package, wherein this slot geometry is defined by one or more slots 5 of a given profile and a width defined by the material removal, and also optionally by their relative arrangement.
