BIAXIALLY STRETCHED NYLON FILM, LAMINATED FILM AND MOLDED BODY

摘要

This biaxially stretched nylon film is a biaxially stretched film that uses a nylon resin as a starting material. This biaxially stretched nylon film is characterized in that: a heat resistant agent is blended into the starting material; the blending amount of the heat resistant agent is from 0.01 part by mass to 0.5 part by mass (inclusive) relative to 100 parts by mass of the nylon resin; and, among the three-dimensional refractive indexes of the biaxially stretched nylon film, if Nx is the maximum in-plane refractive index of the biaxially stretched nylon film, Ny is the minimum in-plane refractive index of the biaxially stretched nylon film and Nz is the refractive index in the thickness direction of the biaxially stretched nylon film, the plane orientation degree (P) defined by mathematical formula (F1) is 0.042 or more. P = (Nx + Ny)/2 - Nz (F1)
