<P>PROBLEM TO BE SOLVED: To provide a laminate that does not leach a foreign substance or residual solvent without using an adhesive, and has superior gas barrier properties, light blocking effect, and strength. <P>SOLUTION: In the laminate, a thermoplastic resin film, a thin film layer including oxidized aluminum or oxidized silicon provided on at least one side surface of the thermoplastic resin film, a barrier film including a gas barrier protective layer provided on the thin film layer, and a polyester nonwoven are laminated so that the gas barrier protective layer of the barrier film and the polyester nonwoven face to, each other. The gas barrier protective layer is made of a film obtained by coating solution including water-soluble polymer having at least hydroxyl and alkoxysilane. The laminate is bonded by forming a bond between an atom in the gas barrier protective layer and an atom in the polyester nonwoven on at least part of an interfacial surface of the gas barrier protective layer and the polyester nonwoven. <P>COPYRIGHT: (C)2013,JPO&INPIT |
