<p><P>PROBLEM TO BE SOLVED: To provide a laminated body with indicator for heat treatment and packaging body using the same, which are excellent in the visibility of presence or non-presence of boiling and retort sterilization treatments, in heat resistance, in solvent resistance, and in water resistance, and whose indication after printing is difficult to be revised by scratching, etc., of the outer surface thereof, while alleviating an economical loss such as the disposal, etc., of left-over ink, thereby realizing excellence in the aspect of cost- and environment-saving, and which allows shortening of switching work hours and reducing of work load, while capable of being adapted to a flexible production system. <P>SOLUTION: The laminated body is so constituted that a base material film layer and a heat-sealing layer are laminated in sequence through the medium of an adhesive layer, while an indicator ink composite for heat treatment, including a binder composed of pigment and a synthetic resin, whose color changes irreversibly by heating, is formed at the laminated face side of the base material layer, by means of the print head of an inject-printer. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
