Outer packaging material for vacuum heat insulating material, vacuum heat insulating material, and articles with vacuum heat insulating material

摘要

PROBLEM TO BE SOLVED: To provide an outer packing material for a vacuum heat insulation material by which the vacuum heat insulation material capable of maintaining a good heat insulation performance can be manufactured, and a vacuum heat insulation material or an article with a vacuum heat insulation material capable of maintaining the good heat insulation performance.SOLUTION: A thermally weldable film 1, and a gas barrier film 2 are sequentially arranged in an outer packing material 10 for a vacuum heat insulation material. Thickness of the outer packing material of the vacuum heat insulation material is 90 μm or less, and a sticking strength of a side of the thermally weldable film of the outer packing material for the vacuum heat insulation material is 15N or more.SELECTED DRAWING: Figure 1
