A fitment has walls with a spout aperture therebetween. Reduced wall thickness results in a reduced amount of plastic in the fitment. An alternative embodiment uses radially extending meltable fins. During installation in a sealing apparatus, a heated mandrel engages the inner diameter of the spout aperture thereby pre-heating and physically supporting the fitment during the installation process. The heated mandrel typically engages the fitment at least one cycle prior to be installed. The fitment may be canoe-shaped.
