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.

A bulk transport bag comprising a main materials-containing body having a side wall, a top wall with a closable inlet and a bottom wall with a closable outlet for the material to be carried, the body comprising a fabric coated with a plastic material, lifting means attached to said body, the lifting means comprising a plurality of fabric webs coated and/or impregnated with a plastic material compatible with the plastic coating of the body, said plastic treated lifting webs each having, on both sides of a lifting loop, linear end portions through which the weight of the load is transferred to the lifting loops from the body of the bag, said linear end portions being secured to the side wall of the plastic coated body by the bonding together of said compatible plastic materials by a weld, and each of said linear end portions, where it separates from the side wall of the bag to start the lifting loop, being retained close to the body by an anti-peel device of fabric coated with a compatible plastic material which is bonded to the plastic coating of the body whereby said load transfer occurs without detachment of the lifting webs.
