PROBLEM TO BE SOLVED: To provide a laminate for vacuum heat insulation material in which laminate strength and seal strength do not deteriorate even when foamed plastic is used as a thermal fusion layer of the laminate, in the laminate for vacuum heat insulation material, and a vacuum heat insulation material using the same.SOLUTION: A laminate for vacuum heat insulation material is used for a vacuum heat insulation material in which a heat insulation core material is coated by the laminate for vacuum heat insulation material, and in which the inside is brought into a vacuum state by degassing. In the laminate for vacuum heat insulation material, the laminate is constituted at least by a gas barrier layer and a thermal fusion layer, and the thermal fusion layer is constituted by an extrusion resin layer, a foamed plastic sheet and a thermal fusion film.SELECTED DRAWING: Figure 1 |
