MB7581 is a type of high-density polyethylene (HDPE) resin that is designed for making caps and closures, especially for food and beverage containers. It is characterized by its multi-modal properties, which provide a good balance of stiffness, high-speed processability (both injection and compression molding), and excellent environmental stress crack resistance (ESCR). This grade also has superior organoleptic properties, meaning it does not impart any taste or odor to the products it contains, making it suitable for taste-sensitive drinks like water, tea, and juice.
