A multilayer film for a deep draw forming, the multilayer film comprising a vinylidene chloride copolymer resin layer as a middle layer; a crosslinked olefin resin layer as a first surface layer; and an ethylene/vinyl acetate copolymer resin layer as a second surface layer;an ethylene/vinyl acetate copolymer resin layer being further provided at least either between the vinylidene chloride copolymer resin layer as the middle layer and crosslinked olefin resin layer as the first surface layer, or between the vinylidene chloride copolymer resin layer as the middle layer and ethylene/vinyl acetate copolymer resin layer as the second surface layer; wherein the multilayer film is obtained by performing a 10 to 40% relaxation treatment in a longitudinal direction and lateral direction (i) on a multilayer biaxially stretched film prepared by irradiating an energy beam from the olefin resin layer side onto a multilayer unstretched film including a vinylidene chloride copolymer resin layer as a middle layer, a olefin resin layer as a first surface layer, and an ethylene/vinyl acetate copolymer resin layer as a second surface layer, an ethylene/vinyl acetate copolymer resin layer being further provided at least either between the vinylidene chloride copolymer resin layer as the middle layer and olefin resin layer as the first surface layer, or between the vinylidene chloride copolymer resin layer as the middle layer and ethylene/vinyl acetate copolymer resin layer as the second surface layer, so as to crosslink the olefin resin, and then biaxially stretching 2.5 to 4 times in the longitudinal direction and lateral direction; or (ii) on a multilayer biaxially stretched film prepared by biaxially stretching 2.5 to 4 times in the longitudinal direction and lateral direction the multilayer unstretched film, including a vinylidene chloride copolymer resin layer as a middle layer, a olefin resin layer as a first surface layer, and an ethylene/vinyl acetate copolymer resin layer as a second surface layer, an ethylene/vinyl acetate copolymer resin layer being further provided at least either between the vinylidene chloride copolymer resin layer as the middle layer and olefin resin layer as the first surface layer, or between the vinylidene chloride copolymer resin layer as the middle layer and ethylene/vinyl acetate copolymer resin layer as the second surface layer, and then irradiating an energy beam from the olefin resin layer side to crosslink the olefin resin. (i) on a multilayer biaxially stretched film prepared by irradiating an energy beam from the olefin resin layer side onto a multilayer unstretched film including a vinylidene chloride copolymer resin layer as a middle layer, a olefin resin layer as a first surface layer, and an ethylene/vinyl acetate copolymer resin layer as a second surface layer, an ethylene/vinyl acetate copolymer resin layer being further provided at least either between the vinylidene chloride copolymer resin layer as the middle layer and olefin resin layer as the first surface layer, or between the vinylidene chloride copolymer resin layer as the middle layer and ethylene/vinyl acetate copolymer resin layer as the second surface layer, so as to crosslink the olefin resin, and then biaxially stretching 2.5 to 4 times in the longitudinal direction and lateral direction; or (ii) on a multilayer biaxially stretched film prepared by biaxially stretching 2.5 to 4 times in the longitudinal direction and lateral direction the multilayer unstretched film, <EOS>
