PROBLEM TO BE SOLVED: To provide a polylactic acid-based resin coated metal sheet for a container in which hydrolysis resistance under the retort treatment environment is excellent, and a number of characteristics that are required for a food product canned raw material are satisfied.SOLUTION: A polylactic acid-based resin coated metal sheet for a container includes a resin layer of at least two layers structure on one surface or on both surfaces, and the polylactic acid-based resin coated metal sheet for a container is that the resin layer of a two layers structure satisfies the following (A) and (B). (A) A resin layer a that becomes an upper layer is a resin layer that contains a polyester in which a coating weight is at least 0.1 g/mand at most 5.0 g/mas a main component, and includes 1.0-50 mass% of at least one selected from the group consisting of (a) a polyamine resin, a polyamidoamine resin, and a polyamide resin. (B) A resin layer b that becomes a lower layer is a resin layer that contains a polylactic acid in which a remaining degree of orientation is at least 5% and at most 30% as a main component, and the polylactic acid includes 0.01-10 mass% of a polycarbodiimide compound. |
