Breathable elastic multilayer film laminate and method of making a breathable elastic multilayer film laminate

March 31, 2009

A breathable, elastic film laminate has been patented. At least one layer of an inherently breathable, elastic polymer film includes a thermoplastic polymer grafted to an elastomer, wherein the thermoplastic polymer contains maleic anhydride and the maleic anhydride couples the thermoplastic polymer to the elastomer. At least two film layers of a polyolefin-based plastic polymer have at least one film layer, which is filled with about 50% to about 70% by weight of a non-thermoplastic filler with alternating layers of the elastic polymer film and the plastic polymer. At least one layer of an inherently breathable, elastic polymer film retracts and the at least one filled film layer of the polyolefin-based plastic polymer buckles so the laminate has a lofty structure and the elastic polymer film is partially delaminated from at least one filled film layer of the polyolefin-based plastic polymer.
