Abstract: A process for reducing the water-vapor permeability of films or coatings made from polymer compositions (Q) comprising beeswax or comprising montan ester wax or comprising mixtures of these, by preparing a composition (Z) comprising Z1) from 40 to 98.5% by weight of at least one polymer compatible with the polymer (Q1) which is the basis of Q, Z2) from 0.5 to 20% by weight of starch or cellulose or a mixture of these as compatibilizer, Z3) from 1 to 20% by weight of beeswax or montan ester wax or a mixture of these, and Z4) from 0 to 20% by weight of at least one additive, where the percentages by weight are based on the total weight of Z, and in a second step combining the composition Z with the polymer (Q1) which is the basis of Q.
