Adhesive label and apparatus for producing the same

摘要

An adhesive agent label includes an adhesive agent layer which is made of an adhesive agent and is formed on one surface of a support. A non-adhesive heat-reactive layer is positioned above the adhesive agent layer and has openings formed by heating at a predetermined temperature or higher. An intermediate layer is positioned between the heat-reactive layer and the adhesive agent layer. The intermediate layer and the heat-reactive layer are formed thinner than the adhesive agent layer. The intermediate layer facilitates the formation of the openings in the heat-reactive layer with good heat energy efficiency and allows the intermediate layer or adhesive agent layer to be exposed through the openings.
