Utjecaj parametara razvlačnog puhanja na svojstva PET boca

The paper deals with the analysis of the influencing factors in the procedure of manufacturing poly(ethylene terephthalate) bottles for packaging of table oil - injection stretch blow moulding. The influence of individual manufacturing parameters on the quality guidelines important in the making of PET bottles for table oil packaging, final volume, and post-shrinkage have been studied. The influencing factors have been determined which affect the volume and shrinkage of PET bottles by using the central composite design.
