Multilayer Container And Method For Producing Regenerated Polyester |
| abstract |
An object of the present invention is to provide a multilayer container in which yellowing of a regenerated polyester at the time of recycle is suppressed. Furthermore, another object of the present invention is to provide a method for producing a regenerated polyester from the aforementioned multilayer container. The multilayer container of the present invention includes a polyester resin composition layer containing a polyester resin (X) and an antioxidant; and a polyamide resin composition layer containing a polyamide resin (Y) and a cobalt salt, wherein the polyamide resin (Y) has a structural unit derived from a diamine and a structural unit derived from a dicarboxylic acid; 50 mol % or more of the structural unit derived from a diamine is a structural unit derived from xylylenediamine; the content of the antioxidant in the polyester resin composition layer is 0.01 to 1% by mass; and the content of the cobalt salt in the polyamide resin composition layer is 100 to 1,000 ppm as expressed in terms of cobalt. |
