Abstract
A fitment for a bag includes an integrally formed spike port, the spike port including an aperture, a puncture barrier film and an internal gasket. The fitment can be a fluoropolymer. The puncture barrier can be a fluoropolymer film. The internal gasket is positioned within the aperture and provides an additional puncture barrier to the spike port. The fitment can be incorporated into a bag by joining two sheets such as fluoropolymer sheets to one another and to the fitment around a perimeter of the sheets. The bag can be used in processes including exposure to or holding at cryogenic temperatures.
