[Problem] To provide a laminated film that has, when being formed as a gas-barrier laminated film provided with an inorganic thin film layer, excellent oxygen gas barrier properties and adhesion between respective layers under normal conditions and even after being subjected to a moist heat treatment, has good adhesion even when subjected to processing such as printing or lamination, and is easy to manufacture at low cost. [Solution] A laminated film characterized by having: a covering layer on at least one surface of a substrate film, the covering layer containing a covering layer resin composition which contains a resin having an oxazoline group as a constituent component; an inorganic thin film layer on the covering layer; and a protective layer that has a urethane resin and is on the inorganic thin film layer, the laminated film having a surface hardness of 350-700 N/mm2, and the protective layer having an arithmetic mean roughness of 0.5-2.0 nm in a 2-µm square. |
