Abstract: Provided are a film for a vacuum heat insulating material which has better gas barrier property as compared with conventional films for a vacuum heat insulating material and which is capable of retaining the excellent gas barrier property even after having been subjected to a folding or deforming process, and a vacuum heat insulating material having a core material hermetically packaged with the film. The film includes a protective layer that is a coextruded and stretched film in which a nylon-based resin, an ethylene-vinyl alcohol copolymer and a nylon-based resin are laminated in this order, a gas barrier layer, and a heat seal layer.
