A method of sealing a foil liner to a hot-filled container includes the steps of aligning a liner engagement surface of a seal head with a liner sealing surface of the container when the container is in a first position, wherein at least a peripheral margin of the foil liner is disposed between the liner engagement and sealing surfaces of the seal head and the container, respectively; applying heat between the seal head and the container to heat and attach the foil liner and the sealing surface of the container, resulting in a sealed package; rotating the sealed package from the first position to a second position; and applying fluid onto at least a portion of the sealed package to cool a head space of the sealed package. The head space is disposed between an inner surface of the container and a product packaged in the sealed package.
