<p>A container bag (10) is disclosed which comprises a body of flexible material and lifting loops (18), in which both the body and the loops contain conductive yarns, characterised in that a patch (26) of conductive fabric is placed between the legs (20) of the lifting loop (18) and the bag body before the lifting loops are secured in place. The lifting loops are normally stitched to the bag body, often using a 'box and cross' stitch pattern (24), to give the necessary mechanical strength. The patch can be manufactured of conductive tape, conductive extruded film, non-woven conductive material, for example, felt or needle punched fabric, or conductive ribbon. A particularly preferred form is conductive tape, especially that available as 'Statex' tape. In a preferred embodiment of the invention, a conductive tape or ribbon (26) is employed which is trapped between the loop and the bag body and extends to the top seam (28) of the bag body where it is sewn into the seam. This gives a particularly good electrical contact.</p> |
