Beschreibung
Zusammenfassung:	An elastomeric laminate that includes at least one facing layer laminated to an elastomeric layer. The facing layer or layers may be nonwoven web(s) made up of thermoplastic filaments formed from a random copolymer or a random copolymer blend. The invention further includes an ultrasonically bonded seam formed by ultrasonically bonding the elastomeric laminate to a substrate, and the method therefor. Un laminado elastomerico que incluye por lo menos una capa de recubrimiento laminada a una capa elastomerica. La capa o capas de recubrimiento pueden ser una tela o telas no tejidas hechas de filamentos termoplasticos formados de un copolimero al azar o de una mezcla de copolimero al azar. La invencion ademas incluye una costura unida ultrasonicamente formada mediante el unir ultrasonicamente el laminado elastomerico a un sustrato, y el metodo para el mismo.
