PROBLEM TO BE SOLVED: To provide a biaxially oriented polyamide resin film roll smoothly susceptible to bag making processing due to lamination in a good yield and capable of efficiently obtaining a package extremely high in peel strength and hot water peel strength and having no S-shaped curl. SOLUTION: This polyamide resin laminated film roll is constituted so that an adhesion modifying layer comprising a copolyester is laminated, the first sample cutting part is provided within a range of 2 m from the winding end of a film and the final cutting part is provided within a range of 2 m from the winding start of the film. In a case that a sample cutting part is provided at every about 100 m from the first sample cutting part, all of samples cut from the respective cutting parts are adjusted so that physical properties such as a boiling water shrinkage factor, a refractive index or the like in a thickness direction become fluctuation width within a predetermined range.
