Abstract
Una bolsa con un cierre reutilizable que se forma de las paredes que definen un sistema de cierre con una abertura o entrada. El sistema de cierre incluye un contorno en forma de macho que se extiende a lo largo de la superficie interna de una de las paredes y un contorno en forma de hembra que se adapta para interconectarse con el contorno en forma de macho y que se extiende a lo largo de la superficie interna de la otra pared. Los contornos en forma de macho y hembra se extruyen a partir de una resina polimérica. Al menos uno de los contornos en forma de macho y de hembra incluye al menos una costilla de otro material polimérico coextruido del mismo y que se extiende longitudinalmente a lo largo del mismo. El material polimérico de la costilla tiene un punto de fusion más bajo que el material polimérico de los contornos, de manera que se fundirá cuando el sello lateral se haga transversalmente a través del sistema de cierre y fluira en y calafateará cualquiera de las aberturas que aun permanezcan después de que se aplanen los contornos de interconexion.
