<P>PROBLEM TO BE SOLVED: To provide a laminate having high air permeability and liquid impermeability, wherein as raw materials of an "air permeability" film, more economical and largely available raw materials which do not need special chemical, although comparatively expensive compared with conventionally used polyolefin such as polyethylene, polypropylenes, and those copolymers, can be used. <P>SOLUTION: The breathable laminate has a liquid-resistant backing film layer having varied vapor permeability that includes breathable thinned localized regions and thicker non-breathable regions, wherein the film layer is co-extensively directly joined with a liquid-and vapor-permeable nonwoven fabric. The breathable laminate can have unidirectional air permeability. The present invention also relates to disposable apparel and absorbent products which incorporate the breathable laminate, and methods of making the breathable laminate. <P>COPYRIGHT: (C)2012,JPO&INPIT |
