Claim 0:
1. A composite comprising:
a. a continuous or a non-continuous first polymer film having a face side and a back side, wherein the first polymer film comprises a first polymer blend comprising a first polymer and a second polymer, wherein the first polymer is immiscible in the second polymer, wherein the first polymer film is stretched in a single stretching direction;
b. a first non-woven fabric having a face side and a back side, wherein the face side of the first non-woven fabric contacts the back side of the first polymer film;
c. a continuous or a non-continuous second polymer film having a face side and a back side, wherein the second polymer film comprises a second polymer blend comprising a third polymer and a fourth polymer, wherein the third polymer is immiscible in the fourth polymer, wherein the face side of the second polymer film contacts the back side of the first non-woven fabric, wherein the second polymer film is stretched in a single stretching direction; and
d. a second non-woven fabric having a face side and a back side, wherein the face side of the second non-woven fabric contacts the back side of the second polymer film,
wherein the composite comprises a machine direction and a cross direction; and
i) wherein the single stretching direction of the first polymer film is arranged in the machine direction of the composite and the single stretching direction of the second polymer film is arranged in the cross direction of the composite; or
ii) wherein the single stretching direction of the second polymer film is arranged in the machine direction of the composite and the single stretching direction of the first polymer film is arranged in the cross direction of the composite.
