  • POLYETHYLENE FOR INJECTION STRETCH BLOW MOLDING AND METHODS THEREOF
    Publication number: 20220267488
    Abstract: A polyethylene-based resin composition for injection stretch blow molding may include a copolymer of ethylene and one or more C4-C8 ?-olefins. The composition may have a density, according to ASTM D792, that ranges from about 0.946 to 0.960 g/cm3 and a melt index (15), as measured according to ASTM D 1238 at 190° C. under a 5.0 kg load, ranging from about 5.0 to 50 g/10 min. A method of producing an article may include injection molding the composition to give a preform; and stretch-blowing the preform to provide the article.
