Resin coated metal sheet, container, and method of evaluation

A resin coated metal sheet comprising

• a metal sheet, and
• a biaxially stretched polyester resin layer formed on at least one face of the metal sheet,
• wherein
• the resin layer contains at least 95 wt % polyethylene terephthalate (PET) and in the PET, 90 mol % or more of structural units are ethylene terephthalate units,
• a movable amorphous amount of the resin layer measured by a temperature modulated differential scanning calorimeter being 30% or more and 46% or less, and
• an intensity ratio I1,096/I1,119 between intensity (I1,096) of a peak attributable to a trans structure of methylene groups in PET around 1,096 cm−1 determined from laser Raman spectroscopic analysis measured by making a plane of polarization of linearly polarized laser light incident on a thickness direction section of the resin coating layer perpendicularly to a thickness direction and intensity (I1,119) of a peak attributable to a gauche structure of methylene groups in PET around 1,119 cm−1 determined from the laser Raman spectroscopic analysis being 1.1 or more and less than 1.5 at a position with a distance of 1 μm from the metal sheet.
