Abstract:
A laminated metal sheet for a metal container lid includes a polyester resin layer formed on a metal sheet. The polyester resin layer is composed of an A and a B layer, wherein the melting point of the A layer is lower than the melting point of the B layer by 20° C. or more, the A layer includes a molten layer where the value of the ratio of a peak intensity I0° to a peak intensity I90° is 1.5 or less, the B layer includes an orientation layer where the value of the ratio of the peak intensity I0° to the peak intensity I90° is 3.0 or more, the thickness of the A layer is within the range from 5 μm or more to less than 30 μm, and the thickness of the B layer is within the range from 0.5 μm or more to less than 6.0 μm.
