The present invention relates to a method of producing a packaging material (10), is carried out at least to the coating steps:
a) providing a substrate (base material) (14), which is the outer side and detached to be packaged products 16 and the packaged goods and the inner side face 18, a substrate 12 having a made of cellulose;
b) it contains at least polyvinyl alcohol and a crosslinking agent, and coating the inner surface 18 of the substrate by at least one layer of an aqueous composition which has a solids content of up to 25% by weight; And
c) drying the layers and cross-linked using a cross-linking agent to polyvinyl alcohol to form a barrier layer (22a, 22b) for the hydrophobic compounds. The present invention relates to a packaging material (10) having at least one barrier layer (22a, 22b) for the hydrophobic compounds further.
