THE INVENTION RELATES TO A MATERIAL LAMINATE (1) WITH A PLANAR DIMENSION AND A THICKNESS DIRECTION PERPENDICULAR TO THE PLANAR DIMENSION, INCLUDING A FIRST LIQUID-PERMEABLE FIBROUS MATERIAL LAYER (2) AND A SECOND LIQUID-PERMEABLE, POROUS AND RESILIENT MATERIAL LAYER (3), WITH AT LEAST ONE OF THE MATERIAL LAYERS (2, 3) INCLUDING THERMOPLASTIC MATERIAL AND THE TWO MATERIAL LAYERS (2, 3) BEING MUTUAL1Y CONNECTED BY THE MATERIAL LAMINATE (1) EXHIBITING BONDING SITES (4) WITHIN WHICH THE THERMOPLASTIC MATERIAL HAS BEEN CAUSED TO AT LEAST PARTIALLY SOFTEN OR MELT AND THEREBY BOND TOGETHER THE TWO MATERIAL LAYERS (2, 3). THE BONDING AREAS ARE ARRANGED IN TWO OR MORE GROUPS (5) WITH AT LEAST TWO BONDING SITES (4) IN EACH GROUP (5), WITH THE GREATEST RELATIVE DISTANCE BETWEEN TWO BONDING SITES (4), WHICH ARE SITUATED ADJACENT TO EACH OTHER, IN A PARTICULAR GROUP (5) BEING LESS THAN THE SHORTEST DISTANCE BETWEEN THE GROUP (5) AND ITS CLOSEST ADJACENT GROUP (5), AS A RESULT OF WHICH THE MATERIAL LAMINATE (1) EXHIBITS BOND-FREE AREAS (6) BETWEEN THE BONDING SITES (4) WITHIN EACH BONDING GROUP (5) WHICH HAVE A HIGHER DENSITY THAN BOND-FREE AREAS (9) OF THE MATERIAL LAMINATE WHICH ARE SITUATED BETWEEN THE BONDING GROUPS (5).
