Abstract
The invention relates to a method for providing a surface of a fiber based substrate with a barrier layer wherein the barrier layer is formed by depositing nanofibers on the surface by the use of electrospinning or meltspinning and wherein the film is formed by post treatment of the substrate. The invention further relates to a substrate comprising such a carrier layer.
