Abstract
The invention provides a carbon-neutral biaxially stretched polyamide film containing a raw material derived from biomass and having high heat-resistance, impact resistance, and folding pinhole resistance, as well as decreased variability in a degree of biomass in the mechanical (longitudinal) direction. The biaxially stretched polyamide film roll contains biaxially stretched polyamide film containing 70-99% by mass of polyamide 6 resin and 1-30% by mass of a polyamide resin in which at least a part of a raw material is derived from biomass, wherein the film roll has a winding length of from 1,000 m to 60,000 m, a width of from 400 mm to 3,000 mm, and variability in a degree of biomass of 15% or less based on radiocarbon 14C measurement of a biaxially stretched polyamide film sample taken from a surface to a core of the film roll at an interval of 1000 m in an MD direction.
