Abstract: The present invention relates to a complex packing, especially adapted for the transport and storage of liquid and pasty products in large quantities, for example of the order of a thousand litres or more, this packing having a large safety factor during handling while full, while enabling a small volume to be obtained when empty. The complex packing is composed firstly of a plastic bag of parallelepiped shape capable of being folded flat when empty, and secondly of a pallet of corresponding parallelepiped shape which constitutes a rigid outer casing for the plastic bag, the pallet comprising a base platform and four dismantlable sides, of which at least two have handles for handling by slings. The platform is furthermore arranged so as to receive a cross-member which may be engaged in the handles of the pallet located immediately below, so as to couple the two pallets together for handling in series.
