Abstract

Tear is a key physical property of polyethylene (PE) blown films. There are many variables which affect the overall tear property such as tear path, plastic deformation wake, and so on. In this study, five blown PE films were prepared and tested by the Elmendorf tear test at five sampling angles, i.e. 0 (MD), 30, 45, 60, 90 (CD) degrees. Tear values were analyzed statistically and the variation of the tear data was investigated based on the observation of the tear samples. The mechanism of severely curved crack, i.e. J-tear, was also studied to understand the tear property variation of blown PE films.
