An insert, having a non-heat sealable surface, is affixed to a first thin film wall. The first wall is aligned with a second thin film wall, with the non-heat sealable surface of the insert facing the interior surface of the second wall. The walls are welded along their periphery to form the contour of the pouch. An adhesive-backed label is then welded to the exterior of the second wall. The insert prevents the interior surfaces of the walls from being sealed together as the adhesive-backed label is welded, simplifying the manufacturing process. The non-heat sealable surface of the insert may be composed of a low friction material to facilitate movement of solid waste within the pouch.
