Summary: | PROBLEM TO BE SOLVED: To provide a multilayer or monolayer plastic container having a barrier layer prepared by blending (i) a polyester resin, preferably an aromatic polyester resin such as a polyethylene terephthalate, (ii) a polyamide material, preferably an aromatic polyamide material, and (iii) an oxygen scavenging material, preferably a transition metal, and to provide a method of manufacturing the same.SOLUTION: In the preparation of the barrier layer, a preform first is prepared by an injection molding process, wherein a preblend containing a diluent polyester, polyamide material and the oxygen scavenging material is added to a base polyester during the injection molding process. The preform is expanded to form a container. |
