Barrier Film And Laminate

Abstract: A barrier film comprising a base material film that contains a polyolefin, wherein when both surfaces of the barrier film are analyzed by means of an x-ray fluorescence spectrometer, the value obtained by dividing the sum of the x-ray fluorescence intensities from chlorine detected on both surfaces by the thickness of the base material film ([the sum of the x-ray fluorescence intensities from chlorine]/[the thickness of the base material film]) is 0.015 kcps/µm or lower.
