Abstract: A disposal bag (1) is disclosed of generally rectangular two-layer construction, with the layers sealed together at their edges on three sides of the rectangle (2, 3, 4). The side walls of the bag are overlaid on the openable side of the bag with extensions (5) which taper inwardly from the edges of the bag and extend outwardly to overlie the outer walls of the bag. The narrower end of each extension (5) is securely fastened to the exterior side wall of the bag at a position (6) so as to form a tunnel (7) each side of the bag into which the thumb and at least one finger may be inserted. At least one of the inside walls of the bag, at the open end of the bag or slightly inset from the open end of the bag, carries a continuous stripe of adhesive material, overlaid by a peel-off strip (9) of release-coated material.
