description A process of producing an article by an extrusion blow molding manufacturing process is provided comprising: melting a copolyester in an extruder to produce a molten copolyester; extruding the molten copolyester through a die to form a tube of molten copolyester parison; clamping a mold having the desired finished shape around the parison; blowing air into the parison causing the parison to stretch and expand to fill the mold to produce a molded article; cooling the molded article; ejecting the article from the mold; and removing excess plastic from the article; wherein the copolyester comprises: at least one terephthalate monomer residue; ethylene glycol residues; a combination of diethylene glycol and at least one glycol residue selected from the group consisting of 1,4-cyclohexanedimethanol residues, monopropylene glycol residues, and 2,2,4,4-tetramethyl-1,3-cyclobutane diol residues; and a germanium catalyst present in the copolyester at a concentration of about 5 to about 500 ppm based on elemental germanium.
