The purpose of the present invention is to provide a multi-layer container and a production method therefor, and a single-layer container production method in which yellowing of a recycled polyester resin is suppressed during recycling, and further, to provide a method for producing the recycled polyester resin from the multi-layer container and the single-layer container. This multi-layer container has at least one layer each of: a polyester resin composition layer including a polyester resin (X) and an amino group-containing compound (A) having the ability to suppress yellowing; and a polyamide resin layer including a polyamide resin (Y). |
