    摘要: The laminated metallic sheet for can is composed of a polyester resin film containing about 50% by mole or more of polyethylene terephthalate on at least one side of a metallic sheet, and shows about 22 to about 25 cm−1 of half value width of shift peak caused by the C═O stretching vibration at 1730±20 cm−1 in the Raman spectra, using a linear polarization laser light, on the film of the laminated metallic sheet for can after heat treatment. The metallic sheet does not generate cracks in the film on the metallic sheet and has excellent workability after heat treatment even to the working after heat treatment such as baking finish and baking print.
