Title:
RESIN-COATED METAL PLATE FOR CONTAINER, AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2024/053203
Kind Code:
A1
Abstract:
Provided is a resin-coated metal plate for a container, in which breakage of a resin coating layer in can making, and planing of the resin coating layer due to insufficient ability to slide during can making can be suppressed, and the plate has excellent adhesion to printing paint after can making. A resin-coated metal plate 1 for a container comprises a polyester resin coating layer 3 on at least one surface of a metal plate 2, the polyester resin coating layer 3 containing 0.010-1.0 mass% of an organic lubricant in which the half-value width of a peak due to C=O stretching vibration in the vicinity of 1730 cm-1 is 24 cm-1 to 28 cm -1, determined by laser Raman spectroscopy analysis from measurement with linearly polarized laser light having a wavelength of 532 nm incident on the surface of the polyester resin coating layer 3 with the plane of polarization of the laser light parallel to the rolling direction of the metal plate, and the contact angle of diiodomethane on the surface of the polyester resin coating layer after heat treatment for two minutes from room temperature to 240°C being 23-40°.
