    摘要: A method of making a microporous laminate sheet having a first film layer and a second layer. The first film layer includes a pore initiator and is bonded to the second layer in order to form a laminate sheet. The laminate sheet is then stretched using at least one CD intermeshing stretcher and at least one MDO stretching unit. Methods of making a microporous film is well as a microporous film laminate are also provided, along with an apparatus for stretching a film or laminate.
