In the present invention, there is disclosed a composition consisting of natural and/or chemically modified starches, glycerol-based plasticizer and a natural filling agent being present in an amount of up to 20 percent by weight. The filing agent is based on mineral natural raw materials, whereby the filing agent is represented by at least one mineral and/or industrial rock being selected from the group consisting of alumosilicates, silicon dioxide, diatomaceous earth and calcium carbonate. Further, the filing agent can also be represented by cellulose. In order to increase resistance to moisture it further consists of a hydrophobizing agent being selected from the group consisting of drying natural oils and/or boiled linseed oil. The hydrophobizing agent is either on the composition surface or it is homogeneously dispersed in the entire volume of the composition. |
