FIELD: technological processes.

SUBSTANCE: invention relates to a method of forming a multilayer elastomeric laminate for clothes and a hygienic product, to a multilayer elastomeric laminate and an article made therefrom. The method involves the following: a) laminating an elastomeric film onto a first substrate to form a laminate web having an elastomeric film surface, where the elastomeric film contains an elastomeric polymer selected from a group consisting of block copolymers of vinyl arylene and conjugated diene monomers, natural rubber, polyurethane rubber, polyester rubber, elastomeric polyolefins, elastomeric polyamides and mixtures thereof, and the first substrate is made from a polymer film, non-woven fabric, a paper article, woven fabric, knitted fabric, scrim, netting or a combination thereof; b) slitting the laminate web to form laminate strips; and c) bonding the surface of the elastomeric film of at least one laminate strip with a second substrate having a width greater than the width of the laminate strip to form a multilayer elastomeric laminate, where the second substrate is made from a polymer film, non-woven fabric, a paper article, woven fabric, knitted fabric, scrim, netting or a combination thereof.

EFFECT: efficient manufacturing of an elastomeric film having good elastomeric properties and good-looking surface structure after activation, which can be rolled and stored without monitoring.
