LyondellBasell produces polypropylene and polyethylene resins selected by customers for use in injection blow molding (IBM) applications. The IBM process involves a two-step conversion - the first step is an injection molding process, followed by a blow molding step - utilizing wheel machinery. Compared to extrusion blow molding, IBM provides lower shrinkage and warpage in the thread section, resulting in improved tightness. Typical customer applications include pharmaceutical packaging for medications and food packaging for yogurt drinks.
