There is provided a liner (14) for a container (10) that provides a gas and moisture barrier. The liner (14) includes a first sealant web (30) of polyethylene that defines a self-supporting layer of the liner. An adhesive layer (31) is applied to an outer surface of the first sealant web (30), and a metal foil layer (32) is adhered to the adhesive layer (31). A second sealant layer (33) is attached to the metal foil layer (32). The second sealant layer (33) may be heat-sealed to the first sealant web (30) so that when the liner (14) is adhered to the inside surface of a container (10) the liner (14) may be sealed to itself with a lap seal. The first sealant web (30) defines a self-supporting layer because it provides structural support to the liner (14). Accordingly, the first sealant web (30) advantageously serves as a carrier web for the liner (14) while the liner is being manufactured. <IMAGE>
