MICROPOROUS BREATHABLE ELASTIC FILM LAMINATES

A breathable, elastic film/support layer laminate includes a thermoplastic elastomer film sheet of a thermoplastic elastomer and a filled semi crystalline predominantly linear polymer. The film includes between about 25 and 70 weight percent filler, between about 5 and 30 by weight percent semi-crys...

More Information
Summary:A breathable, elastic film/support layer laminate includes a thermoplastic elastomer film sheet of a thermoplastic elastomer and a filled semi crystalline predominantly linear polymer. The film includes between about 25 and 70 weight percent filler, between about 5 and 30 by weight percent semi-crystalline linear polymer, and between about 15 and 60 by weight percent elastomeric polymer. The filler is closely associated with the semi-crystalline linear polymer. The film demonstrates a load loss value at a 50 percent elongation of less than 50 percent, and a breathability of greater than 100 g/m¿2</24 hours and is laminated to a nonwoven layer.
