Abstract

La presente invención se refiere a una estructura multicapa coextruida novedosa que posee una relación de halado superior a la relación de halado crítico de cada una de las capas poliméricas, extruidos individualmente. La presente invención también se refiere a un método para obtener la estructura multicapa coextruida. La estructura multicapa coextruida que se puede obtener por el método descrito en la presente permite preparar películas, filamentos o telas no tejidas fundidas por hilado de bajo peso a alta velocidad usando equipos de extrusión convencionales. La estructura multicapa coextruida es especialmente adecuada como hojas de pañales o recubrimientos de empaques flexibles.
