Some embodiments of the present invention include elastomeric films with a basis weight of about 40 gsm or less or about 25 gsm or less. Other embodiments include elastomeric laminates comprising the elastomeric film bonded to one or more substrates (such as nonwoven fabrics). Methods of the making the elastomeric films and elastomeric laminates are also provided.
This application claims the benefit of U.S. Provisional Application No. 61/023,107, filed Jan. 24, 2008, which is herein incorporated by reference in its entirety.
Some embodiments of the invention include a laminate comprising a film that can be a monolayer elastomeric film or a multilayer elastomeric film and at least one substrate. The film and the substrate are laminated together to form the laminate.
Further embodiments include a method for making an elastomeric film comprising extruding a mixture into a layer of a film. The mixture comprises at least one olefin-based elastomeric polymer and at least one draw down polymer.
Two SMMS nonwoven (spunbond-meltblown-meltblown-spunbond) layers made by Fibertex Nonwovens A/S of Aalborg, Denmark with a basis weight of 10 gsm each were extrusion laminated to a monolayer elastomeric film on both surfaces. The elastomeric film comprised 78% VISTAMAXX™ 6102 from ExxonMobil Company, 15% linear low density polyethylene (LLDPE) (ELITE 5800 from Dow Chemical Company), 5% white master batch (Schulman 8500), and 2% processing aid (LUVOFILM 9679 from Lehmann & Voss & Co. of Hamburg Germany) to make a white elastic film. The film was drawn down to 20 gsm to make the extrusion laminated composite of total basis weight of 40 gsm (i.e., 10 gsm nonwoven+20 gsm film+10 gsm nonwoven).
