Zusammenfassung:PROBLEM TO BE SOLVED: To provide a biaxially-oriented nylon coating film which is excellent in chemical resistance, such as acid resistance, and has excellent deep drawing molding property in cool molding, and to provide a laminated packaging material and a molding.SOLUTION: A biaxially-oriented nylon coating film has a coating layer provided on a biaxially-oriented nylon film that uses a nylon resin as a raw material. For the biaxially-oriented nylon film, out of intensity of fluorescence polarization in a film plane, a ratio (maximum value/minimum value) between the maximum value and the minimum value of the intensity of fluorescence polarization parallel to an incident surface is 1.55 or less. The coating layer is formed of at least one selected from a group consisting of polyvinylidene chloride, a vinylidene chloride-vinyl chloride copolymer, maleic anhydride-modified polypropylene, a polyester resin, an epoxy resin, a phenol resin, a fluorine resin, cellulose ester, an urethane resin, and an acrylic resin.
