Abstract

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, 107 A). 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 ).

(2) a sealing surface ( 151 ) around said access passage ( 148 ); and

(D) a liner ( 100 , 100 A) disposed at said container opening ( 108 ) between said closure ( 106 ) and said container ( 104 ), said liner ( 100 ) having
(1) a through hole ( 252 ) to accommodate communication through said access passage ( 148 ) between said interior and exterior of said container ( 104 ),
(2) a metallic substrate layer ( 200 ) having
(a) top and bottom surfaces,
(b) a laterally inward edge surface ( 210 ) that extends between said metallic substrate layer top and bottom surfaces and that is exposed at said liner through hole ( 252 ),
(c) a composition comprising an aluminum alloy wherein said aluminum alloy to the naked eye exhibits substantially no visible corrosion on said top surface after exposure of said laterally inward edge surface ( 210 ) for five months to ketchup initially having a pH of about 4 and a sodium concentration of about 1% by weight at a temperature of 36.7 degrees Celsius,

(3) a first heat-sealable layer ( 212 ) that
(a) is attached to said top surface of said metallic substrate layer ( 200 ), and
(b) has a closure sealing surface heat-sealed to said sealing surface ( 151 ) of said closure ( 106 ),
