A liner (100) and closure (106) are provided for being initially assembled and subsequently installed on a container (104) of a product to create a package (107, 107A). The liner (100) is provided for being disposed between, and sealed to, the container (104) and the closure (106) mounted thereon. The liner (100) includes a metallic substrate layer (200) that is an aluminum alloy and that is located between first and second heat-sealable layers (212, 200), respectively. The liner (100) has a through hole (252), and the metallic substrate layer (200) has a laterally inward edge surface (210) that is exposed at the through hole (252).
