<P>PROBLEM TO BE SOLVED: To provide a laminated metal sheet for a can used for main material of beverage cans and food cans, free from causing molding failure such as pinholes, cracks, fracture, etc., when performing deep-draw manufacture of cans accompanied by large deformation, and excellent in impact resistance. <P>SOLUTION: In an OPBT film, tensile fracture strengths of all the four directions (0° (MD), 45°, 90° (TD), 135°) are equal to or larger than 170 MPa, and tensile fracture elongation is not less than 50% and not more than 200%. One layer or not less than two layers of the OPBT films are laminated on one surface or both surfaces of the metal sheet. <P>COPYRIGHT: (C)2013,JPO&INPIT |
