Zusammenfassung:PROBLEM TO BE SOLVED: To provide a biaxially oriented laminated thermoplastic resin film excellent in gas barrier properties, making it possible not only to manufacture a gas barrier film without including a process such as a coating process, a laminating process or the like but also to reduce a film manufacturing cost or a classifying and recovering cost at the time of recycling. SOLUTION: The biaxially oriented laminated thermoplastic resin film is a laminated film comprising at least three layers including a laminated structure which includes at least one layer (layer A) containing a thermoplastic resin and a layered inorganic compound as main components and comprises laminating layers B mainly comprising a thermoplastic resin on both surfaces of the layer A and the thickness (tA) of the layer A is 1-40% of the total thickness of the film.
