OXYGEN AND WATER VAPOUR BARRIER FILMS WITH LOW MOISTURE SENSITIVITY FABRICATED FROM SELF-CROSS-LINKING FIBRILLATED CELLULOSE Russian patent published in 2018 - IPC B65D81/24 

FIELD: laminated products or materials.

SUBSTANCE: disclosed is a packaging material comprising an oxygen barrier polymer film, wherein the film comprises a polymer obtained by a process comprising steps of: a) oxidising cellulose fibres to ultimately obtain crosslinked cellulose; and b) homogenising the product of step a) to produce fibrils of a width in the range of 1 to 150 nm. Corresponding application is also provided.

EFFECT: providing ways of reducing the affinity of cellulose to water and the water diffusivity.
