BIAXIALLY-ORIENTED NYLON FILM, LAMINATE FILM, LAMINATE PACKAGING MATERIAL, AND METHOD FOR PRODUCING BIAXIALLY-ORIENTED NYLON FILM

摘要

PROBLEM TO BE SOLVED: To provide a biaxially-oriented nylon film having excellent deep drawing moldability at the time of cold molding.;SOLUTION: A biaxially-oriented nylon film is characterized in that, in loss tangent tanδ in dynamic viscoelasticity represented by the following mathematical formula (F1), a peak value of tanδ in γ dispersion is 0.036 or more, and a peak value of tanδ in β dispersion is 0.045 or more. (F1) is: tanδ=E"/E', where E' represents dynamic modulus of elasticity and E" represents dynamic modulus of loss.;COPYRIGHT: (C)2014,JPO&INPIT
