TRANSPARENT BIAXIALLY ORIENTED NYLON FILM FOR VAPOR DEPOSITION

摘要

PROBLEM TO BE SOLVED: To obtain a biaxially oriented nylon film excellent in gas barrier properties which are important characteristics as a film for packaging foods and suitably used as a substrate for a transparent vapor deposition film in which the vapor of an oxide such as silicon oxide or aluminum oxide is deposited. SOLUTION: The characteristic of this transparent biaxially oriented nylon film for vapor deposition is to have an average peak height SRz (μm) of 10 points of the three-dimensional surface roughness and the number of peaks SPc (peaks/0.1 mm2) based on unit area on the film surface satisfying the following ranges: 0.1<=SRz<=0.5 and 10<=SPc<=50.
