The term adhesive compound refers to a product that consists of at least two layers and where at least 1 layer can be removed again. A distinction is made here between the top layer, including the adhesive applied to the reverse side, and the release paper, the so-called release liner. Further distinctions are also made in the classification of the top layer between thermo and non-thermo and the choice of adhesive types.
Non-thermo adhesive compounds, consisting for example of polyolefins such as polypropylene (PP) or polyethylene (PE), coated and partially glossy chromo paper or simpler vellum paper, are used here. These adhesive compounds, in addition to the thermal adhesive compounds already mentioned, are becoming increasingly popular, for example, in the logistics sector. If special requirements are placed on the label, such as increased resistance to environmental influences such as UV radiation, heat, moisture or mechanical resistance such as scratch or tear resistance, these non-thermal adhesive compounds are often used.
