Abstract: A method for attaching a label to a surface of an item. The label includes a carrier layer and a bonding layer. The method includes heating the bonding layer using infrared light such that the infrared light has a maximum spectral irradiance at a peak wavelength. The bonding layer has an absorbing spectral region that spectrally matches with the peak wavelength.

Abstract: A washable label may include a heat-shrinkable layer and a heat-activatable layer. The label may be attached to an item by a method including: heating a portion of the heat-activatable layer by intense visible or infrared light so as to transform the surface of the heat-activatable layer from a non-tacky state to a tacky state, and attaching the label to the item when the surface of the heat-activatable layer is in the tacky state, wherein the intensity of the light is selected such that spatially averaged temperature of the heat-shrinkable layer remains lower than the threshold shrinking temperature of the heat-shrinkable layer. The label may be easily separated from the item by heating the label such that shrinking of the heat-shrinkable layer peels at least a portion of the label away from the item.

Abstract: The invention relates to a removable labels having a multilayer adhesive structure, wherein the first adhesive layer comprises a hot-melt adhesive or tackifier and the second adhesive layer comprises an acrylic pressure-sensitive adhesive. The invention also relates to a method for manufacturing such labels and to use of the labels for labelling of reusable containers.

Abstract: A label having a laminated composite structure and including an adhesive layer, a polypropylene film and a lactic acid based polymer film. The adhesive layer is on a first side of the polypropylene film and a lactic acid based polymer film is on a second side of the polypropylene film. The lactic acid based polymer film induces curling so that the label is removable during washing process from a surface of an item attached.
