Abstract
A liquid-permeable laminate includes at least one layer of spunbond material and at least one layer of spunblown material. The laminate is apertured. The inclusion of the spunblown material results in hole uniformity in the apertured laminate. The invention also includes a method of forming the liquid-permeable laminate.

A liquid-permeable laminate comprising:
- a layer of spunbond material;
- and
- a layer of spunblown material bonded to the spunbond material, wherein the laminate is apertured.
A liquid-permeable laminate comprising:
- two layers of spunbond material;
- and
