Abstract
A laminate material for an elastic diaper closure consists of an elastic carrier film that has a preferred elongation direction, and at least one cover layer that is laminated on the carrier film. The cover layer consists of a fiber non-woven fabric, which contains fibers of an elastic polymer and fiber components of a non-elastic thermoplastic polymer, which have been stretched in the preferred elongation direction by means of an elongation of the fiber non-woven fabric. There is also a method for making the laminate material.
