    摘要： To provide 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. To provide a biaxially stretched polyamide film roll having decreased variability in a degree of biomass in the mechanical (longitudinal) direction. A biaxially stretched polyamide film roll comprising a biaxially stretched polyamide film containing 70% by mass to 99% by mass of polyamide 6 resin and 1% by mass to 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 14 C 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.

    摘要： The feed hopper is, according to the invention, characterised in that the mixing arms (4) have a triangular cross-section and have a rake surface inclined with respect to the horizontal plane by an angle from the range of from 10° to 30°, and further, the shaft (2) of the mixer is terminated from below with a brush (5) whose bristles are directed downwards and are arranged in the outlet port (6) of the feed container (1), wherein the bristle tips of the brush (5) protrude from this outlet port (6).
