Abstract

In laminating resin layers on both surfaces of a metal foil layer by adhering a heat-resistant resin layer to a first surface of the metal foil layer and adhering a heat-sealable resin layer to a second surface thereof, as an adhering method, by employing an adhesive agent unapplied portion forming and adhering process in which the resin layer and the metal foil layer are adhered together by applying an adhesive agent to a region of a joining face of both the layers excluding a part of the region so that an adhesive agent unapplied section is formed, a laminated body having the adhesive agent unapplied section is manufactured. A resin layer removal process for removing a resin layer corresponding to the adhesive agent unapplied section of the laminated body to expose the metal foil layer is performed.

Claims (13)

1. A laminated body comprising:

a metal foil layer including a first surface and a second surface on an opposite side of the metal foil layer from the first surface;

a heat-resistant resin layer including a stretched film;

a heat-sealable resin layer including an unstretched film having chemical resistance; and

a first adhesive agent layer interposed between the first surface of the metal foil layer and the heat-resistant resin layer, and a second adhesive agent layer interposed between the second surface of the metal foil layer and the heat-sealable resin layer; wherein

the first adhesive agent layer includes an adhesive agent section that adheres the metal foil layer to the heat-resistant resin layer, and an adhesive agent unapplied section, adjacent to the adhesive agent section, at which no adhesive agent is interposed between the metal foil layer and a corresponding portion of the heat-resistant resin layer such that the metal foil layer is exposed and not joined to the heat-resistant resin layer at the adhesive agent unapplied section;

the heat-resistant resin layer covers the first surface of the metal foil layer where the adhesive agent section is disposed, and nothing is disposed between the heat-resistant resin layer and the first surface of the metal foil layer at the adhesive agent unapplied section; and

the first surface of the metal foil layer is entirely covered by the heat-resistant resin layer, and the second surface of the metal foil layer is entirely covered by the heat-sealable resin layer.

2. The laminated body according to claim 1 , wherein

the second adhesive agent layer includes a second adhesive agent section that adheres the metal foil layer to the heat-sealable resin layer, and a second adhesive agent unapplied section, adjacent to the second adhesive agent section, at which no adhesive agent is interposed between the metal foil layer and a corresponding portion of the heat-sealable resin layer such that the metal foil layer is exposed and not joined to the heat-sealable layer at the second adhesive agent unapplied section; and

the second adhesive agent unapplied section is interposed between the second surface of the metal foil layer and the heat-sealable resin layer.

3. The laminated body according to claim 2 , wherein

the heat-sealable resin layer covers the second surface of the metal foil layer where the second adhesive agent section is disposed, and nothing is disposed between the heat-sealable resin layer and the second surface of the metal foil layer at the second adhesive agent unapplied section.
