Abstract: A waste container liner and method of manufacture thereof are provided. The method involves the steps of flattening a continuous tubular web of pliable material to form two adjoining layers of material and then slitting one of the longitudinal edges of the flattened web. The adjoining layers are then sealed at regular intervals across their width and perforations are formed across the seals. The web is twice folded longitudinally prior to rolling and detachment of individual liners along the perforations. The waste container liner is made of a unitary piece of pliable material and includes two adjoining layers joined at a longitudinal edge. Each of the adjoining layers has a free longitudinal edge and is sealed at its lateral edge with the other adjoining layer.
