FIELD: chemistry.

SUBSTANCE: invention relates to the technology of obtaining elastomeric materials and particularly to processing surfaces of elastomer films in order to prevent creating in a roll. The method involves forming a film layer from an elastomeric polymer from a block-copolymer of vinyl arylene and conjugated diene monomers, which can be stretched by at least 150% of the initial size and then shrink to not more than 120% of the initial size. An anti-crease coating layer is applied on the first surface of the film. The coating consists of a solvent and an anti-crease coating component selected from lacquer and a surfactant. The film is rolled into a roll, the anti-crease coating component being in contact with the second surface of the film.

EFFECT: efficient method of processing surfaces of elastomer films to prevent creasing in a roll.
