A container bag (10) comprises a body of flexible material and one or more lifting loops (18) characterised in that the body is provided with one or more removable sleeves (20), e.g. four. In addition to the body, the base (14), and optionally the top, may be provided with one or more removable covers which may or may not be attached to or integral with the removable body sleeve (20). A new multi-trip FIBC complete with, say, four sleeves (20) is filled with its first load and transported to its eventual destination. At that point the load is discharged and the FIBC is returned for re-use. Before filling with its second load, the outer sleeve (20) is inspected and, if soiled, is removed exposing the sleeve (20) beneath it. The latter will be in pristine condition, having been protected by the outer sleeve (20). The process is repeated until all the sleeves (20) have been removed when the normal body of the FIBC is exposed and it can be used for what may perhaps be its last trip. In this way, with four sleeves (20), a minimum of five trips can be obtained from the FIBC without the soiling problems previously experienced.
