MANUFACTURING METHOD OF OUTER PACKING MATERIAL FOR VACUUM HEAT INSULATION MATERIAL, MANUFACTURING METHOD OF VACUUM HEAT INSULATION MATERIAL, AND OUTER PACKING MATERIAL FOR VACUUM HEAT INSULATION MATERIAL AND VACUUM HEAT INSULATION MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a vacuum heat insulation material that does not adversely affect a human body even in, for example, use in a house wall, and to reduce an emission amount of VOC without deteriorating heat insulation performance of the vacuum heat insulation material.;SOLUTION: Provided is a manufacturing method of an outer packing material for a vacuum heat insulation material including a first lamination step of laminating a film for first lamination to one surface of a film-like gas barrier material, and a second lamination step of laminating a film for second lamination to the other surface of the gas barrier material after the first lamination step. The second lamination step is performed by a heat laminate method.;COPYRIGHT: (C)2015,JPO&INPIT
