OUTER COVERING MATERIAL FOR VACUUM HEAT INSULATION MATERIALS, VACUUM HEAT INSULATION MATERIAL, AND HEAT INSULATION CONTAINER

摘要

exterior of the vacuum insulation material of the present invention, a barrier film comprising a plastic substrate and an aluminum vapor deposition ethylene stacked on the insulation film-and a vinyl alcohol copolymer film, an aluminum vapor deposition ethylene-vinyl and having a heat seal layer laminated on the alcohol copolymer film. It has at least one side of the plastic base material of the insulation film, formed of a metal or an inorganic oxide, or a mixture containing a metal and an inorganic oxide deposited thin film layer and the aqueous polymer and the (a) at least one alkoxide and one or more alkoxide hydrolyzate of at least one or (b) a coating layer comprising a coating agent to a mixed solution of an aqueous solution, or water and an alcohol containing at least one of tin chloride as a subject are stacked in sequence. ;
