Abstract
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.
Claims12
An adhesive label, comprising:
- a support;
- a pressure-sensitive adhesive agent layer, which forms an adhesive surface formed on one surface of the support;
- a non-adhesive heat-reactive layer which is positioned above the pressure-sensitive adhesive agent layer and in which an opening is formed by heating at a predetermined temperature or higher;
- and
- an intermediate layer which is positioned between the non-adhesive heat-reactive layer and the pressure-sensitive adhesive agent layer, for facilitating the formation of the opening in the non-adhesive heat-reactive layer during the heating.
An apparatus for producing an adhesive label including a support, a pressure-sensitive adhesive agent layer formed on one surface of the support, a non-adhesive heat-reactive layer positioned above the pressure-sensitive adhesive agent layer, and an intermediate layer positioned between the non-adhesive heat-reactive layer and the pressure-sensitive adhesive agent layer,
- the apparatus comprising:
- a storage part for storing the adhesive label in an unheated state;
- and
- heating means for forming an opening in the non-adhesive heat-reactive layer by heating,
- wherein the pressure-sensitive adhesive agent layer is exposed through the opening.
