Abstract
The present invention provides a polyamide based mixed resin laminated film roll formed by winding up a polyamide based mixed resin laminated film comprising a plurality of polyamide mixed resin sheets stacked on top of each other. A first sample cutout portion is provided within 2 m from the winding end of film, and a final sample cutout portion is provided within 2 m from the winding start of film. The roll is regulated so that, when sample cutout portions are provided at intervals of about 100 m from the first sample cutout portion, for all samples cutout from the cutout portions, the elastomer content, tensile modulus of elasticity, thickness unevenness in the longitudinal direction and other properties fall within a predetermined variation range.
