ABSTRACT:
An intermediate bulk container comprises an outer envelope (1 to 6) formed of flexible woven material and having seams (11 to 14). An impervious liner (20) of flexible material is contained within the outer envelope. The liner has tab means (27) lying outside the volume defined within the liner and secured, for example by stitching into a respective seam of the outer envelope. By appropriate location of the tab means on the liner the liner may be securely located within the outer envelope and prevented from distortion relative to the outer envelope.
