The lami- nate (30) comprises a web (10) of plastic film, to one side of which are fixed two mutually spaced, longitudinal strips (14, 16) of non-woven material, while to the other side of the plastic film web (10) - in an area between the two strips (14, 16) on the opposite side of the plastic film web - there is fixed a longitudinal intermediate strip (26) of non-woven material. When used on an absorbent product, the laminate has perforations (42) at least within a portion of the area of the intermediate non-woven strip (26). The invention also relates to a process for manufacture of the sheathing laminate.
