Abstract

La invención se refiere a bolsas de papel provistas de varias paredes y destinadas a contener productos en polvo, en particular yeso. Estas bolsas comprenden una pared interna de papel poroso envuelta por una pared externa de papel y una barrera de vapor distinta de la pared interna de papel. Esta barrera puede ser un revestimiento aplicado sobre la cara interna de la pared externa de papel. Las perforaciones dispuestas en dicha barrera están sensiblemente limitadas a uno y/o dos lados anchos de la bolsa. A lo largo del llenado de las bolsas, el aire puede circular a través de la pared interna y a continuación a través de las perforaciones dispuestas en la barrera de vapor, lo que permite un llenado mecánico de gran velocidad. El deterioro del producto que resulta de las perforaciones que dejan pasar la humedad es inesperadamente igual, y a veces mas pequeño, que la encontrada en otras bolsa. Por consiguiente, la mejora del llenado no va acompañada de una reducción de la duración útil del producto.
