    • A composition for coating a cellulosic packaging material, according to the invention containing the biodegradable materials such as starch, glycerol, which is characterized by being a two-component mixture, wherein the first component comprises a mixture of starch, gelatine and glycerol or a mixture of glycerol and sorbitol, while the second component comprises a mixture of protein ingredients, the porophors and optionally starch. The amount of particular ingredients in the components is such that after the dissolution of both components in water, it permits to obtain a composition with the concentration of starch in the range of 10-17 wt%, gelatine concentration in the range of 10-12 wt% glycerol or a mixture of glycerol and sorbitol in the range of 5-11 wt%, the protein components concentration in the range of 5-10 wt% and the porophors concentration in the range of 3-5.5 wt%. A method for preparing a composition for coating a cellulosic packaging material according to the invention, comprising a mixing of the biodegradable materials such as starch, glycerol, subjecting thereof to the thermal treatment, which is characterized in that, gelatine, glycerol or a mixture of glycerol and sorbitol and starch are dispersed in water using a mechanical stirrer, then said mixture is heated to a temperature in the range of 50-100° C until a uniform consistency is achieved. Subsequently, the mixture is cooled down to a temperature in the range from 35 to 40°C with continuous stirring followed by adding the protein components and the porophors. A heat-insulating packaging material, in particular for the food products according to the invention, containing a cellulosic material coated by a layer of foamable coating which is characterized by that said material has a least one layer of a foamable coating obtained from aforementioned composition coated on the cellulosic material. A method for preparing a heat insulating packaging material, according to the invention, containing a layer of foamable coating which comprises a coating of cellulosic material by a coating from the biodegradable materials, drying and foaming, which is characterized by that, the cellulosic material is a one-side coated by at least one layer of the composition obtained by the aforementioned method. The material is then preliminary dried and subjected to foaming with the application of known heating methods ensuring a uniform heating.
