Abstract

An object of the present invention is to provide a multilayer container in which yellowing of a regenerated polyester resin at the time of recycle is suppressed and a method for producing the same as well as a method for producing a single-layer container. Furthermore, another object of the present invention is to provide a method for producing a regenerated polyester resin from the foregoing multilayer container and single-layer container. The multilayer container of the present invention includes at least one polyester resin composition layer containing a polyester resin (X) and an amino group-containing compound (A) having a yellowing-suppressing ability; and at least one polyamide resin layer containing a polyamide resin (Y).
