1. A laminate comprising at least one support element in the form of a non-woven fabric comprising at least a Spunbond layer having a lower face and an upper face, and at least one non-woven fabric with loops made of a material comprising synthetic thermoplastic polymers, having a lower face and an upper face, wherein said upper face of the at least one support element in the form of a non-woven fabric is secured to said lower face of the non-woven fabric with loops, said at least one non-woven fabric with loops is a product obtained at the end of the formation of a strip of fibers and/or filaments which have been consolidated, said non-woven fabrics with loops comprising fibers and/or filaments and connections between the fibers and/or the filaments made directly by welding or indirectly by means of a layer of adhesive or a layer of binder, wherein the curve representing the force required to stretch the laminate along a given axis of the laminate, as a function of elongation, comprises a segment in which, starting from a zero elongation value, the force increases from zero up to a maximum force, wherein said maximum force corresponds to the rupture of the laminate, and the curve comprises an inflection point (Pi) on said segment, wherein a top of a zone forming loops or a middle(S) of a top part, wherein the top part is a flattened top, is offset in a machine direction, with respect to a central point (P0) equidistant from the two successive connection zones between which the zone forming loops extends.
