Disclosed herein is a breathable film and a breathable, cloth-like film/nonwoven composite made from the breathable film which is stretch-thinned and bonded to a fibrous polyolefin nonwoven web. Certain thermoplastic films such as, for example, linear low density polyethylene films are difficult to thermally bond to, for example, polypropylene nonwoven webs due to the incompatibility of the two polymers. The present invention incorporates a bonding agent into one or both of the two layers thereby making it easier to thermally bond the two layers together. Processes for forming the various composite are also disclosed.
