Abstract
A breathable laminate produced without the use of a needle punch has been disclosed comprising a breathable film, a tie layer bonding material and a flexible woven substrate. The breathable film is one of commercially available breathable films, for example an apertured polyolefin film, that has a high moisture vapor transmission rate (MVTR). The woven substrate provides strength and flexibility, and in preferred embodiments is woven from polyolefin tapes. The tie layer bonding material comprises a polyolefin material that is non-breathable but formed into a porous discontinuous web by the methods and processes disclosed herein. The three layers are joined through a laminating process.
