【Sovereignty Items】 1. A polyamide-based hybrid resin film roll formed by mixing a resin made of a polyamide-based resin and a thermoplastic elastomer and having a width of 0.2 m to 3.0 m and a length of 300 m to 30000 m. The film is wound to form a roll of film. The first sample cut-out portion is disposed within 2 m from the winding end, and the final sample cut-out portion is disposed within 2 m from the winding start point. 1 Sample cut-out portion A test piece cut-out portion is provided every about 100 m, and is characterized by satisfying the following conditions (1) and (2): (1) For each cut out from each of the cut-out portions In the sample, the content of the thermoplastic elastomer component is measured. When the average value of these contents is calculated, the change rate of the content of the thermoplastic elastomer component of all the samples is within ±10% of the average content. (2 ) The rate of change in thickness over the entire length along the length of the wound roll is within ±2% to ±10% of the average thickness.

【Abstract】 To provide a biaxially oriented polyamide-based hybrid resin film roll that can be processed smoothly in high-throughput lamination bags and efficiently obtains S-shaped crimped packages. In the polyamide-based hybrid resin film roll of the present invention, the first sample cut-out portion is disposed within 2 m from the winding end, and the final sample cut-out portion is disposed within 2 m from the winding start point. In addition, a sample cut-out portion is provided at intervals of about 100 m from the first sample cut-out portion, and the content of the elastomer and the tensile modulus of elasticity are applied to all samples cut out from the respective cut-out portions. The physical properties such as boiling water shrinkage and refractive index in the thickness direction were adjusted within the range of change within the prescribed range.
