FIELD: chemistry.

SUBSTANCE: claimed invention relates to technical field of obtaining processed products of mineral fillers, containing calcium carbonate, their application in materials of plastics, in film materials, as well as for aromatising products. In the process of obtaining processed product of mineral product (a) at least, one mineral calcium carbonate containing filler, milled in dry state or in wet state, is obtained. Mineral filler is dried. After that (b) at least, one saturated aliphatic carboxylic acid in liquid or melted state is obtained. Mineral filler from stage (a) is brought in contact at one or several stages, with saturated aliphatic carboxylic acid from stage (b). Processing layer is formed. Processed product of mineral filler is applied for plastics, in particular, for applications for breathing or extrusion films of coatings based on polypropylene (PP), polyethylene (PE), polyurethane and/or polyvinylchloride.

EFFECT: obtaining processed products of mineral fillers, containing calcium carbonate.
