Abstract
The application relates to a coated paper comprising a base paper and at least one coating applied directly or indirectly onto the base paper, wherein the coating comprises a) at least one natural wax and/or at least one carboxylic acid component; and b) at least one natural resin; wherein the permeability of the coated paper for at least one gas is reduced compared to the base paper. Furthermore, the application relates to the coating used for producing the coated paper, the production method, and the packaging produced therefrom.
