【 Sovereignty Items 】 1. Polyamide-based mixed resin laminated film roll, which is a polyamide-based mixed resin laminated laminate of a plurality of polyamide-based resin sheets composed of a mixed resin of a polyamide-based resin and a thermoplastic elastomer The film is wound up to have a width of 0.2 m to 3.0 m and a length of 300 m to 30000 m, and the obtained polyamide-based mixed resin laminated film roll is characterized in that the first film is set within 2 m from the end of the winding of the film. The sample cut-out portion was additionally provided with the final cut-out portion within 2 m from the winding start of the film, and at the same time, when the sample cut-out portion was provided every 100 m from the first sample cut-out portion, the following requirements were satisfied. (1) and (2): (1) When the content of the thermoplastic elastomer component is measured for each sample cut out from each of the cut-out portions and the average value of these contents is calculated as the average content, the thermoplasticity of all the samples is calculated. The rate of change in the content of the elastomer component is within ±10% of the average content; (2) The thickness variation rate in the entire length of the wound roll is within ±2% to ±10% of the average thickness. .

[Abstract] The present invention provides a polyamide-based mixed resin laminated film roll, which can be laminated and processed smoothly with a high yield, and effectively obtains a package without S-curve. The polyamide-based mixed resin laminated film roll of the present invention is obtained by winding a polyamide-based mixed resin laminated film obtained by laminating a plurality of polyamide-based mixed resin sheets, and stopping at a distance of 2 m from the winding of the film. Set the first sample cut-out section within, set the final cut-out within 2m from the start of the winding of the film, and at the same time, set the sample cut-out for every 100m from the cut-out of the first sample. All the specimens cut out from each of the cut-out portions were adjusted in physical properties such as the content of the elastomer, the tensile modulus, or the thickness direction in the longitudinal direction so as to be within a predetermined range of variation.
