The oxygen barrier based on the modified cellulose fiber

There is provided a use of a material comprising fibers as an oxygen barrier， wherein the fibers comprise native cellulose and dialcohol cellulose. There is also provided a material comprising fibers and having a density of at least 1200 kg/m 3， wherein the fibers comprise native cellulose and dialcohol cellulose and the oxygen permeability of the material according to ASTM D3985 is below 30 ml·??m/(m2·kPa·24 h) at 23 °C and 80% relative humidity.
