Title:
GAS BARRIER LAMINATE
Document Type and Number:
WIPO Patent Application WO/2019/031263
Kind Code:
A1
Abstract:
The problem addressed by the present invention is to provide a gas barrier film with excellent acid resistance, transparency, and gas barrier properties. This gas barrier laminate is formed by laminating an inorganic thin-film layer on at least one surface of a polymer substrate. Said inorganic thin-film layer primarily contains Al and Si, and after treatment involving immersion in a 1 mol/L hydrochloric acid aqueous solution for one hour, the ratio of Al content before and after said treatment satisfies the expression (Al content after treatment)/(Al content before treatment) × 100 ≥ 75.
