High Density Polyethylene Composition and Closure |
摘要 |
Disclosed is a high-density polyethylene (HDPE) composition that comprises at least a first high density polyethylene component having a density of 0.940-0.968 g/cm3 and a melt index I2.16 of 0.5-10.0 dg/min and a melt flow ratio (flow index I21.6 at 190° C. divided by melt index I2.16 at 190° C.) of at least 25. A second HDPE component may be included in the composition with melt index I2.16 of greater than 10 dg/min and melt flow ratio of 30 or less. The disclosed compositions are suitable for use in living hinge closure applications. |
