Resin coated metal sheet for container
Abstract:
A resin coated metal sheet for container includes a polyester resin coating layer in which 90 mol % or more of structural units are ethylene terephthalate units. A half-value width of a peak attributable to C═O stretching vibration around 1,730 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 polyester resin coating layer perpendicularly to a thickness direction is 18.5 cm−1 to 22.0 cm−1 at a position with a thickness of 1.0 μm from a metal sheet side of the polyester resin coating layer and is greater than 17.0 cm−1 and 18.5 cm−1 or less at a position with a thickness of 1.0 μm from a surface side of the polyester resin coating layer.
