An apparatus for sealing a foil liner to a container. The apparatus comprises a seal head that includes a body having a first end, a second end, and an axis extending through the first and second ends. The body further includes a sealing surface at the second end thereof facing away from the first end. The seal head further includes fluid path(s) for passing fluid through and out of the seal head and onto the foil liner. A method for sealing a foil liner to a container is also provided wherein a sealing surface of a seal head is aligned with a sealing surface of the container, wherein a peripheral edge of the foil liner is disposed between the sealing surfaces of the seal head and the container. Fluid is then passed through fluid path(s) in the seal head and out of the seal head and onto the foil liner.
