    摘要: A laminate film which exhibits excellent gas barrier properties and lamination strength even after a severe retort treatment or which is small deterioration of gas barrier properties and hardly cause interlayer peeling can be provided. The laminate film comprises a coating layer, a metal oxide layer and a protective layer, with another intervening layer or without any intervening layer, laminated in this order on at least one surface of a polyester substrate film, wherein the coating layer comprises an oxazoline group-containing resin (A) and a polyurethane resin (B), wherein the metal oxide layer comprises a composite oxide composed of silicon oxide and aluminum oxide, and wherein the protective layer comprises a polyurethane resin (D), the polyurethane resin (D) contains a metaxylylene group in an amount of 20 to 33% by mass and a silanol group in an amount of 700 to 1700 mg per kg of a resin constituting the polyurethane resin (D), as a Si element amount contained in the silanol group.
