    摘要: The problem to be solved by the present invention is to provide a biaxially oriented polyamide based mixed resin film roll with which bag forming processing by lamination is able to be performed smoothly and with high yield ratio and at the same time with which packages free of S-shaped curls can be obtained efficiently. A solution for the problem concerns the polyamide based mixed resin film roll of the present invention which includes a first sample cutout portion within 2 m from the winding end of film and a final cutout portion within 2 m from the winding start of film, and when a sample cutout portion is set up in approximately every 100 m from the first sample cutout portion, in all samples cut out from each of the cutout portions, physical properties such as elastomer content, elastic modulus in tension, boiling water shrinkage percentage and refraction index in the thickness direction are adjusted to be within a predetermined range of variation range.
