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.

Abstract: The invention concerns a foil, in particular for food packaging, said foil consisting of a polymer P1 or a mixture containing: P1: 0.1 to 100 wt %. of a rubber-elastic block copolymer P1 comprising at least one block S, which comprises vinylaromatic monomer units, incorporated by polymerization, and which forms a hard phase, and at least one elastomer block B/S, which comprises units, incorporated by polymerization, both of a vinylaromatic monomer (S) and of (B), and which forms a soft phase, the glass transition temperature Tg of the block S being more than 25 DEG C and that of the block B/S being less than 25 DEG C, and the phase-volume ratio of block S to block B/S being such that the hard phase portion in the total block copolymer is 1 to 40 vol % and the portion of the diene is less than 50 wt %; P2: 0 to 99.9 wt % of a thermoplastically formable and/or duroplastic polymer P2; P3: 0 to 70 wt % of further additives and forming auxiliary agents, the total of the weight percentages of constituents P1 to P3 being 100 %.
