Title: RESIN-COATED METAL PLATE FOR CONTAINER AND PRODUCTION METHOD THEREFOR
Abstract:
Provided is a resin-coated metal plate that is for a container, that maintains excellent extraction properties, and that stably satisfies various characteristics. The resin-coated metal plate for a container comprises a resin layer (A) that has a multilayer structure and that comprises a polyester as a main component thereof on a side that serves as a container inner surface when forming the metal plate on a container. 1) The resin layer (A) contains 85 mol% or more of terephthalic acid. 2) The resin layer (A) is configured from at least two layers, and the uppermost resin layer (a1) that comes into contact with the container contents contains 0.10-2.0 mass% of a wax compound with respect to the uppermost resin layer (a1). 3) The maximum value of the Raman band intensity ratio (I1720/I1615) when a cross-section of the uppermost resin layer (a1) is measured using a laser polarization plane that is parallel to the surface of the resin layer (a1) is in the range of 0.45-0.80. 4) The thickness of the uppermost resin layer (a1) is 0.5-10 µm. 5) The thickness of the resin layer (A) excluding the thickness of the uppermost resin layer (a1) is 5-20 µm.
