ABSTRACT:
A method for manufacturing a liner for a waste container is provided, comprising the steps of extruding a flexible envelope, the envelope having ends; flattening the envelope so as to form a top side and a bottom side; cutting a lengthwise slit in the top side of the envelope substantially along the centerline of the envelope; sealing the ends of the envelope; folding the envelope along the centerline; and rolling one end toward the other to form a rolled bundle. A waste container liner may be formed by this process, comprising a flexible envelope including a top side; a bottom side; first and second ends; gusseted side panels connecting the top side and the bottom side; a lengthwise slit in the top side between the first and second ends substantially along the centerline of the envelope; and wherein the top and bottom sides are sealed together at the first and second ends.
