Abstract
A container liner comprises at least one sheet bounded along portions thereof to form at least one peripheral seam, with the at least one sheet including a first fluoropolymer layer, a barrier film layer, and a third layer bonded along at least peripheral portions thereof. Any of such layers may be peripherally bonded to form a gap or pocket therebetween, or bonded along substantially entire major surfaces thereof. Surface modification may be employed to facilitate bonding of materials having otherwise dissimilar surface energies. The resulting liner is adapted for storing and dispensing high purity chemical reagents, e.g., by placing the liner in an overpack, and applying pressurizing gas to a space between the liner and the overpack for progressive compaction of the liner to dispense its contents.
