PROBLEM TO BE SOLVED: To provide a laminate which has biodegradability, and is excellent in processability, and in which the adhesion between the polyester resin layer and a base material layer has been improved, and to provide a bag and a container formed by using the laminate.SOLUTION: A laminate has a base material layer containing a plant-derived component, an outermost layer containing aliphatic polyester, and an intermediate layer that exists between the base material layer and the outermost layer. The intermediate layer contains polyester different from the aliphatic polyester contained in the outermost layer. When the entire structural unit derived from a dicarboxylic acid is 100 mol% in the polyester contained in the intermediate layer, the proportion of a structural unit derived from a terephthalic acid is 20-30 mol%. A bag and a container are formed using the laminate. |
