The invention concerns a linerless self-adhesive material obtained starting from a self-adhesive material with a liner, by means of a process that comprises the delamination of the liner from a self-adhesive layer, activation of the liner or self-adhesive layer, transferral of the liner over the self-adhesive layer and re-lamination of the two components so as to produce the linerless self-adhesive material. The liner or the self-adhesive layer is coated with a thermo-adhesive that allows for permanent lamination of the liner located on the self-adhesive layer.
