Abstract: Disclosed herein is a breathable film (12) and a breathable, cloth-like film/nonwoven composite (10) made from the breathable film which is stretch-thinned and bonded to a fibrous polyolefin nonwoven web (14). Certain thermoplastic films such as, for example, linear low density polyethyelene 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 composites are also disclosed.

Abstract translation: 本文公开了一种透气膜（12）和由透气膜制成的透气的布状膜/非织造复合材料（10），其被拉伸变薄并粘合到纤维聚烯烃非织造纤维网（14）上。 某些热塑性膜，例如线性低密度聚乙烯膜由于两种聚合物的不相容性而难以热粘合到例如聚丙烯非织造纤维网上。 本发明将粘合剂结合到两层中的一层或两层中，从而使得两层热粘合更容易。 还公开了用于形成各种复合材料的方法。
