<p><P>PROBLEM TO BE SOLVED: To provide a laminate metal can which exhibits good foamability in actual use environments when filled with beer without largely increasing a can cost, a manufacturing method of a film for use of the metal can, a manufacturing method of a metallic plate for use of the metal can, and a manufacturing method of the metal can. <P>SOLUTION: The laminate metal can for beer has a laminated resin layer on the metallic plate on the internal side of the can. The laminated resin layer has a groove on its surface. The groove has a width of 5.0μm or less in its cross section. The groove width narrows on the side of a steel plate. A part with a groove width of 1.0μm or less in the groove depth direction has a depth of 0.5μm or more. In addition, a total length of the groove per unit area on the internal surface of the can is at least 10 mm/mm<SP>2</SP>and at most 300 mm/mm<SP>2</SP>. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
