Abstract

In this study, we report on the influence of lamellar morphology and orientation on the dart impact strength of linear low-density polyethylene (LLDPE) blown films. Evidence confirming the importance of lamellar anisotropy on the impact strength performance of such films is presented. Specifically, lower degree of lamellar orientation (more random orientation) is shown to favor higher impact strengths. We also note that the films stretch considerably during the measurement of dart impact strength with the initial morphology influencing the stretching process.
