A label structure and a method for obtaining the label structure are described. A self-adhesive web of material continuously advances at a predetermined speed along a path between an ultrasonic horn assembly and a rotary anvil, the self-adhesive web of material of a type originally used for the obtaining of labels or other self-adhesive products. The ultrasonic horn assembly is further activated to move along its vertical axis and further transmits ultrasound wave signals when contacting the web of material. The rotary anvil welds predetermined strips onto the web of material, the predetermined strips inhibiting silicone from cross bands and from side longitudinal bands of a silicone layer of the silicone-coated plastic tape of the web of material, which will form back end cross bands, intermediate transversal bands and longitudinal bands, such that the silicone layer of the silicone-coated plastic tape and end cross bands, intermediate cross bands, and longitudinal bands of the self-adhesive tape are permanently coupled, respectively, over the end cross bands, intermediate cross bands, and longitudinal bands of the silicone layer of the silicone-coated plastic tape.
