Gas Barrier Performance
Gas Impermeability (Gas Barrier Performance)
GOHSENOL™ as a film formed by itself or on paper or other materials exhibits extremely high impermeability to various gases such as oxygen, nitrogen, hydrogen, carbon dioxide, and helium under low humidity conditions. However, moisture and ammonia can permeate.
