SIBUR has developed a new bimodal high-density polyethylene grade, HD21550 CC, for the production of 38-mm caps used to seal juices, dairy products, tea, and other beverages. The new grade was developed in response to the requirements of closure manufacturers, for which processing stability on high-performance lines, retention of product geometry, sealing performance, and compliance with the hygienic and organoleptic standards of the beverage industry are critical.
