A method for reducing or eliminating plate-out during the process used to produce stretch blow molded containers from polyester preforms by crystallizing the low molecular weight polyester molecules in or on the preform exterior surface before stretch blow molding the preform into a container. The molecules are crystallized using a crystallization process selected from (1) treating the outer surface of the preform with a solvent that is capable of crystallizing low molecular weight polyester molecules in polyester or (2) heating the outer surface of the preform to a temperature and for a time suitable for crystallizing low molecular weight polyester molecules in polyester. Plate-out is reduced because the crystallized molecules do not migrate out of the preform and form plate-out deposits on the mold.
