The present application relates to a linerless self-adhesive label, method for labelling an item, and to a labelled item.

The invention relates to a label (30) for identifying an object, the label comprising a plurality of layers (L.sub.1, L.sub.2, L.sub.3), wherein each layer comprises a matrix material (15), and each layer comprises a plurality of identifier elements (10, 11); the plurality of identifier elements (10, 11) are dispersed in the matrix material (15), and the plurality of layers (L) are arranged so that at least two layers at least partially overlap each other. Further, the invention relates to a precursor of a label (30) for identifying an object and a method of manufacturing a label (30) for identifying an object.

A printed linerless face laminate includes a release layer including a release agent, a second layer including a thermoplastic polymer, a second adhesive layer, a first layer including a thermoplastic polymer or fiber-based material, and a first adhesive layer including a pressure sensitive adhesive, wherein the print is on one or more printable surface(s) between the first layer and the second layer. A method for producing the printed linerless face laminate is also described.

Disclosed embodiments may relate to a time-dependent color-changing label for a product. The label may include a first layer comprising a plurality of particles, the particles comprising a time dependent color-changing material that changes color after a predetermined time period, the predetermined time period being greater than one month. The label may also include an attachment structure attaching the first layer to the product. In certain embodiments, the first layer may include a polymer, and the particles may include glass microspheres containing the time-dependent color changing material. The particles may be embedded in the polymer.

An adhesive label comprises: a face layer, and an adhesive layer,
wherein the face layer comprises semi-crystalline polymeric film, the adhesive layer consists of one or more adhesive sub-layers, a lowermost adhesive sub-layer of said adhesive sub-layers comprises transparent polymeric adhesive, the thickness of the face layer is in the range of 10 μm to 50 μm, the thickness of the adhesive layer is in the range of 8 μm to 25 μm, the thickness of the adhesive layer is smaller than 95% of the thickness of the face layer, an uppermost sub-layer of said adhesive sub-layers is in contact with the face layer, and the refractive index of the uppermost adhesive sub-layer is in the range of 80% to 98.5% of the refractive index of the semi-crystalline polymeric film.

A freshness label structure includes a label structure and a sealing member. The label structure includes a base material and a phosphor layer. The phosphor layer includes an aggregation-induced phosphor fixed to the base material. The sealing member is impermeable to aqueous liquid, seals the freshness label structure, and includes a porous member impermeable to aqueous liquid and permeable to gas.

The self-adhesive label is produced in relief in order to visually and/or tactilely simulate a decorative molding of a material of a container or a decorative seal or stamp applied to the container. The self-adhesive label comprises, successively: a layer of adhesive, a flexible plastic sheet, an undercoat varnish on the flexible plastic sheet, and an overcoat varnish on the undercoat varnish. The undercoat varnish and the overcoat varnish are configured to repel each other, so that the overcoat varnish is retracted into the shape of a drop.
