The present invention relates generally to the field of multi-layer flexible packaging material. In particularly, the present invention relates to a multi-layer flexible packaging material comprising a paper layer, an aluminium layer, a nanoclay barrier coating layer, and a sealing layer applied to the surface of the nanoclay barrier coating layer representing the inner surface of the multi-layer flexible packaging material, said multilayer flexible barrier material being deprived of a polyolefin layer, such as a polyethylene (PE), polyethylene terepthalate (PET) or a polypropylene (PP) layer. The present invention further relates to the use of the multi-layer flexible packaging material in accordance with the present invention to package dry food.
