Abstract : This study presents the development in 1.8L eagle® shape of an edible oil bottle made of polyethylene terephthalat (PET) virgin resin. The study is depending on increasing the stretch ratio between the bottle and preform. The new preform design offers several advantages including light-weight, reduce electrical consumption, maintaining good quality level and improve some mechanical properties (ductility and toughness) in many bottle areas. Mainly the study was divided to two main parts which are the experimental work and finite element method. In the experimental work big modification is made in to the injection unit to make the new preform fit to the new stretch ratio. The modification was on the pair of injection cores, cavity, guide ring and two pairs of split insert. Also in the experimental work performed 126 tension tests for it is standard samples from bottles before and after the modification, the tension tests were conducted in seven areas in the bottle for two directions (axial and hoop). Finally the experimental work checked the new bottle quality level by load test, stacking test and center closure leak. For finite element work used to make solid modeling of the complex bottle shape by SolidWorks then Abaqus was to used get the stress and displacement in the bottle areas, also compare the new bottle is compared to the old one for the thickness in both bottles. As a result of this study, too many positive points were got and the major one was 16.2 % reduction in the bottle weight which will reduce the material cost.
