biaxially oriented nylon film, laminated film, the production method of laminate packaging material and biaxially oriented nylon film

摘要

Biaxially oriented nylon film of The present invention, biaxially to the nylon resin as a raw material A stretched film of the fluorescence polarization intensity in the film plane, when the I parallel to the maximum value of the parallel fluorescence polarization intensity to the incident surface, the maximum value of the vertical fluorescence polarization intensity to the incident plane is I vertical, P which is defined by the following formula (A) ( ) is characterized in that at least 0. P ( ) = (I parallel -I vertical) / (I + I parallel vertical) ... (A)
