The bag is made from a polyethylene sheet and has a mouth with at least one sheath along its edge, the sheath containing an inextensible ribbon which is graspable from outside through a hole cut in the sheath, in order to close the bag after filling. An elastically extensible ribbon is fastened at its opposite ends to the material of the bag. When the bag is received in a rigid bin with its upper margin overturned over the bin rim, the elastic ribbon is pulled radially, looped and released around the overturn of the bag to clamp it around the bin.

1. A garbage bag made from a sheet of a synthetic material, having a mouth with at least one sheath along its edge, the sheath containing an inextensible ribbon which is graspable from outside through a hole cut in the sheath, further comprising at least one elastically extensible ribbon, which is fastened with its opposite ends to the material of the bag, substantially transversely to the bag near its mouth. 2. The garbage bag of claim 1, the bag being made from a folded polyethylene sheet in which both upper edges are folded over and welded to build two of said sheaths, an inextensible ribbon being received in each of said sheaths, wherein said elastically extensible ribbon is also received in one of said sheaths and is also graspable through said hole. 3. The garbage bag of claim 1, wherein the inextensible ribbons and the elastic ribbon are colored in contrasting, coded colors. 4. The garbage bag of claim 1, wherein the elastic ribbon is applied along said sheath externally to the bag. 5. The garbage bag of claim 1, wherein the bag as well as the inextensible ribbons and the elastic ribbon are of a polyethylene material, the material of the elastic ribbon having a high elastic deformability. 6. The garbage bag of claim 1, wherein the bag is made from a folded polyethylene sheet, its side edges adjacent to the fold being bonded by respective welds, wherein the opposite ends of the inextensible ribbons and of the elastic ribbon are bonded to the bag material by the same welds bonding said edges. 7. The garbage bag of claim 1, wherein the elastically extensible ribbon has an elastic stretch greater than 200%. 8. The garbage bag of claim 7, wherein the elastically extensible ribbon has an elastic stretch larger of about 250%.
