| Abstract: | The influence of loading rate on the tension properties of the low - density polyethylene film in longitudinal and landscape orientation was studied. It showed that the tension strength and the elongation at break in landscape orientation are larger than those in the longitudinal, and the effect of extension rate on the tension strength and the elongation at break is not significant. |

| Keywords: | low - density polyethylene film loading rate tensile strength elongating rate |
