    Abstract: 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.

    Abstract: self-adhesive linerless label for labelling containers, preferably made of PET, the label being particularly adapted to be removed from the container during recycling operations. The label derives from a linerless self-adhesive material that includes a liner made of plastic material having a density greater than 0.8 g/cm3, preferably between 0.9 g/cm3 and 1.5 g/cm3, more preferably between 1 and 1.4 g/cm3 at 25° C. The material is preferably PET or PP, The linerless self-adhesive material also includes a self-adhesive film having a polymeric material with a density of less than 0.9 g/cm3 at 25° C., preferably between 0.6 g/cm3 and 0.9 g/cm3, more preferably between 0.7 and 0.8 g/cm3 at 25° C. The liner and the self-adhesive material are in permanent contact by a thermo-adhesive.
