An object of the present invention is to provide a multilayer film and a package body of which the thickness can be reduced than that of a conventional multilayer film, by having a good impact resistance, flex resistance, and anti-pinhole property. A multilayer film 100 according to the present invention includes a repeatedly laminated part 130. The repeatedly laminated part 130 is formed by alternately and repeatedly laminating a first layer 131 and a second layer 132. The first layer 131 consists mainly of a polyamide resin (excluding elastomers). The second layer 132 consists mainly of a copolymer of an olefin-based hydrocarbon having carbon number of 2 to 4 and a vinyl group-containing monomer.
