SHEATH BAG FOR VACUUM HEAT INSULATION STRUCTURE AND VACUUM HEAT INSULATION STRUCTURE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a sheath bag for a vacuum heat insulation structure that indicates excellent heat insulation performance and can obtain a vacuum heat insulation structure in which deterioration of heat insulation performance is extremely less even in long use, and to provide a vacuum heat insulation structure using the same.SOLUTION: A sheath bag for a vacuum heat insulation structure uses a laminate I containing a deposition film A in which when lights are radiated from the opposite side of the deposition surface of the deposition film A, and the number of transmitted lights is measured as the number of bright points, the number of bright points is 200 or less per a film size of 4 mm×3 mm.
