Abstract: A package and a method of manufacturing the package. The package is the type of sack known as a bulk bag comprising an outer cover provided with a liquid-tight liner. Through the interior of the bag extends a string-shaped member in the form of a rope which is tied by means of a knot to the welded-together bottom portion of the bag. The upper portion of the bag is gathered about the rope to form a package-handling member in the shape of a loop. The cover is welded together also at its upper end in order to prevent penetration of liquid into the bag interior. The bag is provided with a filler valve.
