Abstract: A liner for lining a generally rectangular-bottomed container. First and second outer faces of the liner are connected together along opposed first and second edges and are separable from one another along a top edge extending between the first and second edges. An inwardly gusseted bottom face of the liner extends between opposed bottom portions of the first and second edges. First and second lines of weakness are spaced inwardly from the first and second edges and extend from the top edge, across the outer faces, into the inwardly gusseted bottom face.
