OUTER BAG FOR VACUUM INSULATION STRUCTURE AND VACUUM INSULATION STRUCTURE USING SAME

摘要

The purpose of the present invention is to obtain a vacuum insulation structure, which exhibits excellent insulation performance and with which the decrease in insulation performance is very small even when used for long periods. Provided is an outer bag for a vacuum insulation structure obtained by using a laminate [I] comprising a vapor deposition film (A) for which, when light is irradiated on the vapor deposition film (A) from the side opposite to the vapor deposition surface and the number of the permeating light is measured as the number of bright spots, the number of bright spots is 200 per 4 mm × 3 mm film size or less.
