HAFNOCENE CATALYZED POLYETHYLENE FILMS HAVING RAPID CLING DEVELOPMENT |
摘要 |
Polyethylene films may include a polyethylene copolymer polymerized in the presence of a hafnium-based metallocene catalyst, wherein the polyethylene comprises a solubility distribution breadth index (SDBI) less than or equal to 23°C; a melt index (12) less than 1.5; a flow index (121) of from about 16 to about 28; and a melt flow ratio (121/12) of from about 18 to about 23. The film has a cling value that is at least 60% of a cling value the film has at 48 hours after time zero, and wherein time zero is equal to less than 24 hours. |
