ABSTRACT:
A bulk transport bag comprises a bag body made of a flexible fabric coated with a plastic material such as PVC, and lifting webs defining lifting loops, which lifting webs are made of a fabric web impregnated and/or coated with a plastic material such as PVC compatible with that coated on the body fabric, the lifting webs and bag body being bonded together by a weld through the compatible plastics materials effectively to form an integral structure. Anti-peel devices are preferably provided at the upper periphery of the side wall of the bag body, where the bonded regions of the lifting webs separate from the bag body to form the lifting loops.
