Abstract

A process is provided for making a blow-molded PET container comprising a wall having a density of between about 1.370 g/cc and 1.385 g/cc, a heat-induced crystallinity of from about 18% to about 25%, and a strain-induced crystallinity of from about 55% to about 75%, wherein the PET container, when filled with a liquid having a temperature of from about 100° C. to about 132° C. or when subjected to a pasteurization or retort process, will not experience a change in volume of greater than 3%.
