Elastic composite material comprises a film, which is covered at both sides from a single- or multi-layered non-woven fabric support, and is formed as a co-extruded film (1), whose first surface is formed from a first elastic film layer (2) of a styrene-block copolymer, and its opposite second surface is formed from a second film layer (3). A first adhesive layer (5) is arranged between the first elastic film layer and a first non-woven fabric support. A second adhesive layer (7) is arranged between the second film layer and a second non-woven fabric support. Elastic composite material comprises a film, which is covered at both sides from a single- or multi-layered non-woven fabric support, and is formed as a co-extruded film (1), whose first surface is formed from a first, elastic film layer (2) of a styrene-block copolymer, and its opposite second surface is formed from a second film layer (3), which exhibits a lower elasticity than the first film layer. A first adhesive layer (5) is arranged between the first elastic film layer and a first non-woven fabric support. A second adhesive layer (7) is arranged between the second film layer and a second non-woven fabric support. The adhesion between the second film layer and the second adhesive layer is less than the adhesion between the first film layer and the first adhesive layer. The composite material exhibits regions, in which the second adhesive layer of the second film layer and/or the second film layer of the first film layer are detached.
