摘要: The invention relates to a self-adhesive label comprising a bilayer comprising at least one layer of paper coupled to at least one polymeric film, wherein the polymeric film is coated, on the surface opposite to the surface of coupling to the at least one paper layer, with a layer of pressure sensitive adhesive (PSA), wherein the adhesive can have "wash-off" properties such as to cause a label to peel off from a surface by washing with a 1.0%-2.0% NaOH solution at 65-75°C according to the FTM26 method, or according to the QT 500 or QT 508 protocols, published by EPBP; or the adhesive has a force lower than the shrink force of the polymeric film. The label also comprises an intermediate layer placed between the polymeric film and the PSA adhesive, capable of promoting the adhesion of the PSA adhesive to the polymeric film, and/or the polymeric film is treated with a corona treatment, a flame treatment or a plasma treatment, on the surface opposite to the surface of coupling to the at least one paper layer.
