FIELD: molded preforms and ready containers.
SUBSTANCE: container is made of injection molded preform. The preform has opened part defining container neck, intermediate part creating container body and sealed part defining container base. Preform comprises polyethyleneterephthalate copolymer including diol-formed component having repeated ethylene glycol units and diol-formed ethylene glycol-free component, as well as dibasic-formed component including periodic terephthalic acid units and terephthalic acid-free dibasic-formed component. Summary content of ethylene glycol-free diol-formed component and terephthalic acid-free dibasic-formed component is from 0.2 mol fraction to value, which is not greater than 2.2 mol fraction.
EFFECT: decreased container weight, increased strength and reduced power inputs for container production.
