Tearable biaxially oriented nylon film, tearable laminate film, method of manufacturing tearable laminate packaging material and tearable biaxially oriented nylon film

摘要

tearable biaxially oriented nylon film of the present invention include nylon 6 (hereinafter, also referred to as Ny6) and meta-xylylene adipamide (hereinafter, also referred to as MXD6) and the tearable biaxially oriented, including as a raw material a nylon film, among the three-dimensional refractive index of the film, a maximum refractive index value of the film plane and Nx, the minimum refractive index value of the film plane and Ny, the refractive index in the thickness direction of the film in the case where the value and Nz, is to satisfy the condition that the surface orientation degree (P) is represented by the following formula (F1). P = (Nx + Ny) / 2-Nz 0.040 (F1)
