Abstract

In this paper, eleven (11) blown and compression molded polyethylene films (2 HDPE and 9 LLDPE films) were prepared and tested by tensile tests and Elmendorf tear tests. In the case of compression molded polyethylene films, there is no preferred orientation so that the samples were prepared with no orientation and with constant thickness. In the case of blown films, two sampling angles, i.e. MD (0° in MD) and CD (90° in MD), were selected. Tear values were analyzed statistically and the variation of the tear data was investigated based on the observation of the tear samples. The effect of tensile properties in a given direction on tear properties in the opposite direction was investigated. The relationship between tear properties obtained from the compression molded film and the blown film were compared and modeled using the geometric mean of the tear values.
