摘要: A deep stretch forming process for producing low distortion, biaxially oriented, heat set, hermetically sealable hollow containers of high molecular weight saturated linear polyesters comprised stretching an injection molded heated contoured preform into a die by means plunger, annealing or setting and then cooling the formed container prior to said removal from die.
