The reinforced sheet is adhesively secured to the two-ply tube, and the lower end of the two-ply tube is folded and adhesively secured together to form a folded satchel bottom for the receptacle. The upper end of the two-ply tube is gathered and clamped to provide structure for lifting the receptacle.
