ABSTRACT:
A container bag having a base, side walls and lifting loops, the base having a reclosable bottom opening, characterised in that a liner is provided attached to the bag, the liner having a cone shaped lower portion. Preferably the liner is made from a lighter, and less expensive, material than the outer bag. Conveniently the liner is attached to the outer bag by means such as clips, adhesive or sewing, and may advantageously be sewn to the outer bag along the top thereof. Preferably the cone-shaped lower portion of the liner terminates in an opening which may be tied off, as is known in the FIBC art. The bottom closure of the outer bag may be a "petal" or "pyjama" closure, but advantageously is larger than may have been common hitherto. The cone-shaped lower portion of the liner will depend through the opening in the outer bag when the latter is untied.
