Patent

CA 2140587

A container bag which comprises a body of flexible material having lifting loops across the corners thereof and baffles to maintain a square configuration is characterised in that a liner is provided sealed to the baffles. The use of baffles in square configuration FIBC's has hitherto prevented the use of a liner since the baffles would prevent the liner fitting properly in each of the corners of the bag. In accordance with the present invention the baffles within the liner and are sealed to it before the latter is affixed to the FIBC. In this manner, an FIBC can be produced which has both baffles giving it a square configuration and a liner to prevent ingress of moisture and air. The liner taking on the 'square' configuration imparts it to the FIBC as a whole. The baffles may protrude from the liner and be attached to the FIBC walls, or they may be wholly within the liner. In either case, the liner will preferably be impervious to air and moisture and may be a polyolefin sheet material.
