An elastic film laminate includes a first film and at least one second film. The first film is elastomeric in at least one direction and can be reversibly stretched by a length &Dgr;l during a deformation without demonstrating substantial residual deformation &Dgr;l . The second film is made of a deformable plastic connected with the first film in localized connection regions less than the entire length of the first film. The second film has received a permanent deformation &Dgr;l significantly greater than the residual deformation &Dgr;l , by means of a common deformation by a length &Dgr;l , so that the second film is permanently deformed between the localized connection regions. In a renewed deformation of the film laminate above a limit range of deformation, where &Dgr;l>&Dgr;l applies, the second film exhibits a reaction force that causes the tensile force required for further stretching of the laminate to increase suddenly. The tear resistance of the second film is adjusted so that if the tensile force is increased further, stretching of the second film layer by at least 10% of its length is still possible beyond &Dgr;l before tear.
