RESIN-COATED METAL SHEET FOR CONTAINER AND PROCESS FOR MANUFACTURING SAME

WIPO Patent Application WO/2015/125461

A1

Provided is a resin-coated metal sheet which is for use in a container and which can ensure excellent take-out properties and fulfill various characteristics stably. This resin-coated metal sheet has a resin layer (A) which has a polyester -based multilayer structure and which lies on a side such that the metal sheet is formed into a container with the side as the inner surface of the container. The resin-coated metal sheet satisfies the following requirements: (1) the resin layer (A) contains at least 85mol% of terephthalic acid; (2) the resin layer (A) is composed of at least two layers, and the uppermost resin layer (a1), which is to come into contact with contents, contains a wax compound in an amount of 0.10 to 2.0mass% relative to the uppermost resin layer (a1); (3) concerning the Raman band at 1615cm-1 in Raman spectroscopic analysis of the uppermost resin layer (a1), the maximum value of ratio (IMD/IND) of the peak intensity in the machine direction to the peak intensity in the normal direction is 1.0 to 4.0; (4) the thickness of the uppermost resin layer (a1) is 0.5 to 10μm; and (5) the thickness of the resin layer (A) exclusive of that of the uppermost resin layer (a1) is 5 to 20μm.
