LAMINATED METAL SHEET FOR CONTAINER, METHOD FOR PRODUCING METAL CAN, AND METHOD FOR EVALUATING METAL SHEET MOLDABILITY

摘要

Provided are a laminated metal sheet for containers that has excellent formability after heat treatment performed after coating, printing, etc. and is suitable for DR cans, a method for producing a metal can using the above metal sheet and a method for evaluating the formability of a metal sheet.The crystal structure of a top layer of a laminate layer of the laminated metal sheet for containers and the crystal structure inside the laminate layer are controlled in a sophisticated manner. Specifically, the intensity ratio I 2968 /I 3085 of the Raman band intensity (I 2968 ) at a peak position around 2,968 cm -1 to the Raman band intensity (I 3085 ) at a peak position around 3,085 cm -1 that are obtained by laser Raman spectroscopy is used. This intensity ratio is controlled within a specific range.
