Polypropylene film was used to examine the effect of different extension temperature, extension speed and extension rate during polymer film extension process. This study use a lab developed extension device that can change the extension temperature, extension speed and extension rate, and observed the super-structure in polymer film using polarizing optical microscope and scanning electron microscope. The experiment shows that polypropylene film exhibits similar kite-shaped and damaged structure during extension process, and the extension temperature and extension rate impact the uniformity of kite-shaped and damaged structure, the structure of polymer film is more uniform under increasing extension temperature .The shape of kite-shaped structures are larger, longer and thinner under high extension rate; on the other hand, the effect of extension speed on polymer structure is not obvious during polymer film extension.
